• What is the cause and solution for SAP error message RSDMD128 - Not all master data could be deleted ?

  The SAP error message RSDMD128, which states "Not all master data could be deleted," typically occurs when there are dependencies or references to the master data that you are trying to delete. This can happen in various scenarios, such as when the master data is still being used in reports, queries, or other data models.
  Causes:
  
  Active References: The master data you are trying to delete is still being referenced by other objects, such as InfoObjects, queries, or data models.
  Data Integrity Constraints: There may be data integrity constraints that prevent the deletion of certain master data.
  Authorization Issues: The user may not have the necessary authorizations to delete the master data.
  Data Locking: The master data might be locked by another process or user, preventing deletion.
  Hierarchy Dependencies: If the master data is part of a hierarchy, it may not be possible to delete it without first removing it from the hierarchy.
  
  Solutions:
  
  
  Check Dependencies: Use transaction codes like RSD1 (for InfoObjects) or RSA1 (for Data Warehousing Workbench) to check if there are any active references to the master data you are trying to delete. Remove or deactivate these references before attempting to delete the master data again.
  
  
  Review Authorizations: Ensure that the user attempting to delete the master data has the necessary authorizations. You may need to consult with your SAP security team to verify this.
  
  
  Unlock Data: If the master data is locked, identify the user or process that is holding the lock and resolve the issue. You can use transaction SM12 to check for locks.
  
  
  Remove from Hierarchies: If the master data is part of a hierarchy, you will need to remove it from the hierarchy before deletion. This can typically be done in the hierarchy maintenance transaction.
  
  
  Use the Correct Deletion Method: Ensure that you are using the correct method for deletion. For example, if you are using a mass deletion tool, ensure that it is configured correctly.
  
  
  Check for Data Integrity Issues: If there are data integrity issues, you may need to resolve these before you can delete the master data. This could involve cleaning up related data or correcting inconsistencies.
