Purchase Order Fields Relevant to Printouts of Changes

Understanding Purchase Order Fields for Change Printouts

In SAP Materials Management (MM), it's crucial to track and manage changes to purchase orders efficiently. One key aspect is determining which fields in purchasing documents are relevant to printouts of changes and how these are reflected in change notices. This ensures transparent communication with vendors and compliance with internal processes.

How Change Relevance Is Controlled in SAP

SAP provides configuration settings to define the relevance of fields in purchasing documents for change outputs. This setup governs whether a field change is included in the printout of purchase order modifications.

Key Configuration Transactions

1. Transaction SM30 – Table T166C

Use transaction SM30 to access table T166C, where you can configure the change relevance of specific fields. This is the primary table for customizing which fields should trigger a change message in printouts.

2. Transaction OMF6 – Define Text Numbers

Transaction OMF6 is used to define text numbers that control how text outputs are generated in change notices. These can be assigned directly or indirectly using routines.

Steps to Define Fields Relevant to Change Notices

To include additional fields in the change printout process, follow these steps:
  1. Enter the Table and Field Names

  2. Identify the exact table and field whose change you want to track.
  3. Select Document Categories

  4. Choose the relevant purchasing document types (e.g., purchase orders, contracts) for which the field should be monitored.
  5. Assign a Text Number or Routine
    • Direct Assignment: Use a predefined text number.
    • Indirect Assignment: Use a custom routine.

Implementing Custom Logic Using User Exits

If standard routines do not meet your requirements, implement custom logic using the user exit:

User Exit: EXIT_SAPLMEDRUCK_001

This user exit allows advanced evaluations and custom behaviors during the printout process of purchasing document changes.

Why This Matters for Your SAP System

  • Better Vendor Communication: Ensures suppliers are updated on relevant changes.
  • Regulatory Compliance: Maintains a clear audit trail for procurement processes.
  • Improved Accuracy: Reduces manual intervention and errors in change documentation.

Conclusion

Configuring purchase order fields relevant to printouts of changes is a critical task for maintaining accuracy and consistency in SAP MM. By using tools like SM30, OMF6, and user exits such as EXIT_SAPLMEDRUCK_001, businesses can efficiently manage change outputs and maintain operational clarity.

Frequently Asked Questions (FAQs)

Q1. What is table T166C used for in SAP?

Table T166C is used to configure which fields in purchasing documents are relevant for change printouts.

Q2. How do I assign a text number for change notices?

Use transaction OMF6 to define and assign text numbers to control how text appears in change notices.

Q3. What is the purpose of EXIT_SAPLMEDRUCK_001?

This user exit enables custom logic to be executed during the printout of purchasing document changes.

Q4. Can I use custom routines instead of text numbers?

Yes, you can use a routine for indirect text assignment to control the printout behavior.

Q5. Are these configurations client-dependent?

Yes, typically these configurations are client-specific and must be repeated across clients if needed.
