• What is the cause and solution for SAP error message MD758 - No data was changed ?

  The SAP error message MD758 ("No data was changed") typically occurs in the context of Material Requirements Planning (MRP) or when trying to update or change data in the system, such as during the execution of a transaction that involves changing material master data, production planning, or similar activities.
  Cause:
  
  No Changes Made: The most straightforward cause of this error is that the system detected no changes to the data you were trying to update. This can happen if you attempt to save data that is already in the same state as it was before.
  Data Locking: Another potential cause could be that the data you are trying to change is locked by another user or process, preventing any modifications.
  Validation Errors: Sometimes, the system may have validation rules that prevent changes if certain conditions are not met, leading to the perception that no data was changed.
  Authorization Issues: If the user does not have the necessary authorizations to make changes to the data, the system may not allow the update, resulting in this message.
  
  Solution:
  
  Check for Changes: Ensure that you are actually making changes to the data. Review the fields you are trying to update and confirm that they differ from the existing values.
  Review Data Locking: Check if the data is locked by another user. You can use transaction codes like SM12 to view and manage locks.
  Validation Rules: Review any validation rules or conditions that might be preventing the changes. Ensure that all required fields are filled out correctly and that the data meets any necessary criteria.
  Authorization Check: Verify that you have the necessary authorizations to make changes to the data. If not, contact your SAP security administrator to request the appropriate permissions.
  Transaction Logs: Check transaction logs or system messages for additional details that might provide insight into why the data was not changed.
