Various methods are available for debugging in ABAP

Here's a breakdown of the most common ones:

Ø  1. /h (Traditional Debugger):

This is the classic and most common way to start the ABAP debugger. You can enter /h in the command field of any SAP screen, and the next time you execute a transaction or program, the debugger will start. This method is widely used and provides a comprehensive set of debugging features.

Ø  2. Setting Breakpoints:

BREAK-POINT Statement: You can insert the BREAK-POINT statement directly into your ABAP code. When the program execution reaches this line, the debugger will be triggered. This is useful for targeted debugging of specific parts of your code. You can set breakpoints for specific users as well.

External Breakpoints: You can set external breakpoints for specific user IDs. This is useful when debugging code that is executed by other users. Use transaction SAAB to maintain external breakpoints (also accessible from Utilities->Settings->ABAP Editor->Debugging).

Breakpoint at Statement: While in the ABAP Editor (SE38, SE80), you can set a breakpoint directly in the code by double-clicking in the left-hand margin next to the line number. This is a convenient way to debug during development.

Watchpoints: These allow you to stop the debugger when the value of a specific variable changes.

Ø  3. Transaction SE38 / SA38 (ABAP Editor):

When executing a program from the ABAP Editor (SE38 or SA38), you have options to start the debugger:

With Variant: This allows you to specify input values for your program before it starts and enter debugging mode.

Debugging: Starts debugging immediately when you execute your program.

Ø  4. Transaction SM50 (Work Process Overview):

This transaction shows you the currently active work processes. You can select a process and choose "Debug" to attach the debugger to a running program. This is useful for debugging programs that are already in execution.

Ø  5. Transaction ST05 (Performance Trace):

While primarily used for performance analysis, the SQL trace within ST05 can indirectly help with debugging by showing you the exact SQL statements being executed by your program. This can help pinpoint issues with database access.

Ø  6. Transaction SAT (Runtime Analysis):

SAT is used for performance analysis but can also be valuable during debugging to analyze the program flow and identify potential bottlenecks or unexpected behavior.

 

Ø  Choosing the Right Debugging Method:

Ø  The method you choose depends on the situation:

v /h: Quick and easy for general debugging.

v Breakpoints: Targeted debugging of specific code sections.

v SE38/SA38: Convenient for debugging during development.

v SM50: For debugging running processes.

v ST05 and SAT: Useful for performance-related debugging and analyzing program flow.

 

Ø  Remember to deactivate debugging mode (/hx) when you're finished to avoid performance issues on the system.

 

Ø  This overview provides the most commonly used methods. More specialized debugging techniques exist for specific scenarios, but this should cover most everyday debugging tasks in ABAP.

Simple explanation about SAP BRF+/BRFplus

 

                           SAP Business Rules Framework plus (BRF+) is a powerful tool within the SAP ecosystem for defining and managing business rules, providing a centralized, transparent, and agile way to handle the complex logic driving various business processes.

Let's explore it with examples:

What is SAP BRF+ ?

Ø  BRF+ is essentially a rule engine, a separate "brain" that makes decisions based on provided information. This "brain" is decoupled from the specific application, allowing the same rules to be used across different SAP modules (like Finance, Logistics, HR, etc.) and even non-SAP systems.

Ø  This replaces hardcoding logic directly into applications, which can be difficult to maintain. BRF+ lets you define these rules in a user-friendly environment, ranging from simple calculations and validations to complex decision trees.

Ø  It enables you to define business rules without the need of writing ABAP code.

Ø  The generated Business Rules can be incorporated into other SAP programs or Substitution/Validation rules.

Ø  BRF+ is not new and even not directly related to SAP S/4HANA, but with the release of SAP S/4HANA 1610, BRF+ gained more attention since it is launched as the go-to solution for some business processes. The most important ones are the changes in output management for Billing and Purchasing.

Ø  It is a part of SAP NetWeaver ABAP stack.

Ø  The t-code used is BRF+ or BRFplus.

 Key Features and Benefits, Illustrated with Examples:

Centralized Rule Management: Imagine a company with different discount rules for various customer groups scattered across multiple sales systems. BRF+ consolidates these rules into one central repository, simplifying maintenance and ensuring consistency.

Transparency and Auditability: If a discount is applied incorrectly, BRF+ allows you to trace back exactly which rule was applied, when, and by whom, providing full transparency and aiding in issue resolution.

Improved Agility and Flexibility: Let's say a new customer group requires a special discount. With BRF+, a business user can quickly create and deploy this new rule without needing a developer to change code, enabling faster responses to market demands.

Reduced Development Costs and Time: A validation rule for customer credit limits can be defined once in BRF+ and used across sales, finance, and delivery processes, avoiding redundant development effort and saving time and resources.

Simplified Governance and Control: For regulatory compliance (e.g., SOX), BRF+ ensures that all financial calculations follow approved rules and provides a clear audit trail for demonstrating compliance.

 Examples of BRF+ Applications:

Calculating Discounts: A retail company uses BRF+ to determine discounts based on customer segment, purchase volume, and promotional offers.

Validating Data: A bank uses BRF+ to validate customer data during account opening, ensuring all required information is provided and accurate.

Determining Eligibility: A government agency uses BRF+ to determine eligibility for social benefits based on applicant income and other criteria.

Routing Workflows: An insurance company uses BRF+ to route claims to the appropriate department based on claim type and severity.

Managing Pricing: A manufacturing company uses BRF+ to manage complex pricing rules based on product configuration, raw material costs, and market conditions.

 

Why is it so Popular in the SAP World?

                      BRF+'s popularity stems from its ability to streamline complex business logic, enhance agility, cut development costs, and boost transparency. It empowers businesses to be more adaptable, improve decision-making, and ultimately achieve better results.

                     In essence, BRF+ offers a more modern, efficient, and flexible way to manage business rules in SAP, moving away from hardcoded logic towards a centralized, transparent, and business-user-friendly approach. This is why it has gained so much traction within the SAP community.

Simple explanation about IDOC with definition , structures & message types

What is IDOC?

IDOC is simply a data container used to exchange information between any two processes that can understand the syntax and semantics of the data.

In other words, an IDOC is like a data file with a specified format which is exchanged between 2 systems which know how to interpret that data.

IDOC stands for ” Intermediate Document”

IDOC Basics

We can view an IDOC using transaction WE02 or WE05

IDOC Consists of 3 Parts mainly

Control Record:

The administration part (Control Record)- which has the type of idoc , message type, the current status, the sender, receiver etc. This is referred to as the Control record.

Ø  All control record data is stored in EDIDC table. The key to this table is the IDOC Number

Ø  It contains information like IDOC number, the direction(inbound/outbound), sender, recipient information, channel it is using, which port it is using etc.

Ø  Direction ‘1’ indicates outbound, ‘2’ indicates inbound.

Data Record:

The application data (Data Record) – Which contains the data. These are called the data records/segments.

Ø  Data record contains application data like employee header info, weekly details, client details etc

Ø  All data record data is stored in EDID2 to EDID4 tables and EDIDD is a structure where you can see its components.

Ø  It contains data like the idoc number, name and number of the segment in the idoc, the hierarchy and the data

Ø  The actual data is stored as a string in a field called SDATA, which is a 1000 char long field.

Status Record :

The Status information (Status Record)- These give you information about the various stages the idoc has passed through.

Ø  Status record is attached to an I-DOC at every milestone or when it encounter errors.

Ø  All status record data is stored in EDIDS table.

Direction : ‘1’ indicates outbound, ‘2’ indicates inbound.

 

Ø  Outbound :Statuses 1-42 are for outbound

Ø  Inbound: statuses 50-75 are for inbound

 

IDOC Types

Ø  Basic type

                The basic type defines the core structure and content of an IDoc. It represents the standard definition of a specific business document, like a purchase order, invoice, or sales order. The basic type determines the segments (data fields grouped together) that are included in the IDoc, the sequence of those segments, and the data types within each segment. Think of it as the blueprint or template for a particular kind of IDoc. It's identified by a name, for example, ORDERS01 (for purchase orders).

 

Key Characteristics of Basic Types:

Fixed Structure: The structure of a basic type is predefined and cannot be easily modified.

Reusable: They are designed to be used across various applications and business processes.

Standard Segments: They typically include standard segments common to many IDoc types, like control information, partner information, and status information.

Basis for Extensions: Basic types serve as the foundation for creating extension types, allowing for customization without altering the original standard.

 

Ø  Extension

             An extension type builds upon a basic type by adding custom segments or fields to accommodate specific business requirements. It allows you to enhance the standard IDoc structure without modifying the underlying basic type. This ensures compatibility with standard processes while incorporating company-specific data. For example, you might want to add a field for a customer loyalty number to the standard purchase order IDoc. You would create an extension type based on ORDERS01 to incorporate this additional field.

 

Key Characteristics of Extension Types:

 

Customization: They enable tailoring IDocs to meet unique business needs without disrupting standard functionality.

Inheritance: They inherit all the segments and fields from the underlying basic type.

Flexibility: You can add, delete, or modify segments and fields within the extension type.

Version Control: Extensions are managed with versions, allowing for controlled updates and modifications.

List of IDOC Message Types

Ø  ORDERS - Purchase Order

Ø  ORDCHG - Purchase order Changes

Ø  DESADV - Shipping Notifications

Ø  INBDLV - Inbound Delivery

Ø  REMADV- Payment Advice Processing

Ø  MATMAS - Material Master

Ø  ARTMAS - Article Master

Ø  CREMAS - Supplier Master

Ø  DELINS - Forecast Delivery schedule

Ø  MBGMCR- Post goods movement

Ø  ORDRSP - PO Confirm

Ø  SHPCON - Ship Confirmation/PGI

         

Purchasing:

Ø  ORDERS (Purchase Order): This is the core IDoc for transmitting purchase orders to vendors. It contains all the necessary details about an order, such as materials ordered, quantities, prices, delivery dates, and other conditions. Think of it as the electronic equivalent of a paper purchase order.

 

Ø  ORDCHG (Purchase Order Change): Used to communicate changes to an existing purchase order. This could include modifications to quantities, delivery dates, prices, or other order details. It ensures that both the buyer and vendor are working with the latest version of the order.

 

Ø  ORDRSP (Purchase Order Confirmation/Response): Sent by the vendor back to the buyer as a confirmation or rejection of a purchase order, or to suggest changes. It might contain updated delivery dates, confirmed quantities, or explanations for rejected items.

 

Ø  INBDLV (Inbound Delivery): Represents a delivery of goods from a vendor. It contains information about the expected delivery date, shipping details, and the materials included in the delivery. This allows the buyer to prepare for receiving the goods.

 

Ø  REMADV (Remittance Advice): Used in payment processing to provide details about which invoices are being paid. It links payments to specific invoices and helps with reconciliation. (You listed "Payment Advice Processing" which is the function this IDoc supports, not the IDoc type name itself).

 

Ø  MBGMCR (Post Goods Movement): Documents the movement of goods within the company after they are received. This allows for updating inventory levels and tracking the movement of materials through the warehouse.

 

Logistics and Supply Chain:

Ø  DESADV (Despatch Advice/Shipping Notification): Sent by the vendor to notify the buyer that goods have been shipped. It contains details about the shipment, including tracking information, carrier details, and the shipped quantities. This allows the buyer to track the shipment and plan for its arrival.

 

Ø  DELINS (Forecast Delivery Schedule): Used to communicate planned future deliveries from a vendor. This helps the buyer anticipate upcoming shipments and adjust their planning accordingly. It's essentially a forecast of deliveries.

 

Master Data:

Ø  MATMAS (Material Master): Used to exchange information about materials, including descriptions, units of measure, weights, and other attributes. This ensures that both systems have consistent information about the materials being traded. Crucial for data synchronization between systems.

Ø  ARTMAS (Article Master - often industry-specific): Similar to MATMAS but often used in specific industries like retail or fashion, for managing articles or finished goods. It contains information specific to the industry, such as sizes, colors, or styles.

Ø  CREMAS (Customer Master/Supplier Master): You listed this as "Supplier Master," but CREMAS typically refers to Customer Master. For vendors/suppliers, the IDoc type LIFNR is associated with the Vendor Master. These IDocs are used to exchange information about business partners, including addresses, contact details, payment terms, and other relevant information.

Shipping and Delivery:

Ø  SHPCON - (Shipping Confirmation/Post Goods Issue - PGI): Confirms the shipment of goods and updates the delivery status. This is often linked to the creation of a goods issue document in the shipping system.

 

Key Considerations:

Ø  Versions: These IDoc types can have different versions (e.g., ORDERS01, ORDERS02, etc.), each with slight variations in structure.

Ø  Segments: Each IDoc type is composed of segments, which contain the specific data fields.

Ø  Customization: Companies often customize these standard IDocs by adding custom segments to accommodate specific business needs.

 

IDOC Message Status

Inbound IDOC:

51 - Application Document Not Posted

52 - Application Document Not fully Posted

53 - Application Document Posted

Outbound IDOC:

01- IDOC Generated

02 - Error Passing data to Port

03- Data Passed to port OK

IDOC Reprocessing Method

WE19 - With help of Existing IDOC no we can make the field changes then new IDOC no will be   generated

BD87 - Pass new IDOC no and process it

IDOC Partner Profiles - WE20

Ø  BP - Benefits Provider

Ø  GP - Business Partner

Ø  KU - Customer

Ø  LI - Vendor

Ø  LS - Logical System

Ø  US – User

The Outbound Process

Steps Involved –

  1. Create segments(WE31)
  2. Create an idoc type(WE30)
  3. Create a message type (WE81)
  4. Associate a message type to idoc type(WE82)
  5. Create a port(WE21)
  6. If you are going to use the message control method to trigger idocs then create the function module for creating the idoc and associate the function module to an outbound process code
  7. Otherwise, create the function module or stand-alone program which will create the idoc
  8. Create a partner profile(WE20) with the necessary information in the outbound parameters for the partner you want to exchange the idoc with. Trigger the idoc.

The Inbound Process

Steps Involved-

  1. Creation of basic Idoc type (Transaction WE30)
  2. Creating message type (Transaction WE81)
  3. Associating the Message type to basic Idoc type (Transaction WE82)
  4. Create the function module for processing the idoc
  5. Define the function module characteristics (BD51)
  6. Allocate the inbound function module to the message type(WE57)
  7. Defining process code (Transaction WE42)
  8. Creation of partner profile (Transaction WE20)

What is CDS view in SAP with simple explanation

 CDS views in SAP are a way to define and consume data models in a standardized way. Think of them like well-organized blueprints of your data that are easy for different parts of the system to understand and use.

Here's a simplified explanation:

Imagine we  have a big library with thousands of books (your data). Finding a specific book can be difficult if there's no organized system.

**That's where CDS views come in. They're like creating a library catalog (the view) that organizes the books based on different criteria (author, genre, publication year). **

Instead of searching through every single book (data table),we can use the catalog (CDS view) to quickly find the books (data) we need based on the defined criteria.

Example:

Let's say we're working with sales data in SAP. We have different tables for customers, orders, and products.

Without CDS: We would  have to write complex queries joining these tables every time we need information like "total sales for a specific customer."

With CDS: We can define a CDS view called "SalesAnalysis" that combines relevant data from those tables. The view would include fields like:

Customer Name (from the Customer table)

Order Date (from the Order table)

Product Name (from the Product table)

Total Sales Amount (calculated from relevant fields)

Now, we can use this "SalesAnalysis" view to quickly get the information we need without writing complex SQL queries each time.

Key Advantages of CDS Views:

Simplicity: Easier to read and write than traditional database queries.

Reusability: Defined once and can be reused by multiple applications and reports.

Performance: Optimized for efficient data retrieval.

Semantic Richness: Can include annotations and metadata for better understanding.

Remember: This is a simplified explanation. CDS views can be much more complex and powerful, involving different types of joins, associations, and calculations.

To get specific technical details, we might find it helpful to check the official SAP documentation or online resources dedicated to SAP development.

1860315 - Error in P101 price when creating STO / valuation type not used




Issue:



  1. Create a stock transport order in transaction ME21N for a split valuated material.
  2. Check condition tab at item level, condition type P101.
  3. System takes the price from material for supplying plant on plant level instead of the valuation type(NEW) level.

 Cause

When a stock transport order is created, the system displays the valuation price of the material that is specified for the supplying plant in Accounting 1 view in the material master. The system does not check the entered valuation type for the price determination.

As per the sap standard behavior , derive the plant-specific price from the material master of the supplying plant from accounting view.

Note: We can refer OSS Note 1860315 - Error in P101 price when creating STO / valuation type not used.

 
Solution: System design, no solution in the standard system. We have to implement a enhancement in the LV61AA46 / XKOMV_KBETR_ERMITTELN, where the price for the P101 condition is determined.
We have to add below condition in that if a specific calculation schema need to apply  calculation schema name and valuation type field otherwise only valuation type field is enough.


               IF komk-kalsm = 'ZXXXXX'. "Calculation Schema Name

          mtcom-bwtar = komp-bwtar.

        ENDIF.
