• What is the cause and solution for SAP error message AH428 - To-date must not be changed ?

  The SAP error message AH428 ("To-date must not be changed") typically occurs in the context of date management within SAP applications, particularly when dealing with time-dependent data such as validity periods for master data or transaction records. This error indicates that the "To-date" field is being modified in a way that is not allowed by the system's rules or logic.
  Cause:
  
  Invalid Date Change: The user is attempting to change the "To-date" of a record that is already in use or has dependencies that prevent modification.
  Data Integrity Rules: SAP enforces certain data integrity rules that prevent changes to dates that would lead to inconsistencies in related records or transactions.
  Locked Records: The record may be locked by another user or process, preventing changes to the date fields.
  Configuration Settings: Certain configurations in the system may restrict changes to date fields based on business rules.

  Check Dependencies: Review any dependencies or related records that may be affected by the change. Ensure that changing the "To-date" will not violate any business rules.
  Unlock Records: If the record is locked, check with your system administrator or the user who has locked the record to unlock it.
  Use Valid Date Ranges: Ensure that the "To-date" you are trying to set is valid and does not conflict with existing records. The "To-date" should be greater than or equal to the "From-date" and should not overlap with other existing records.
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific guidelines related to the transaction or module you are working with.
  Transaction Codes: If applicable, use transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) to check the underlying tables and data integrity.
