CF199 - Details

• The SAP error message CF199 "No PRT data was changed" typically occurs in the context of Production Resource Tools (PRT) when you are trying to change or update PRT data in a production order or related transaction, but the system detects that no actual changes were made to the PRT data.
  
  Cause:
  
  No Changes Made: The most common cause of this error is that the user attempted to save changes to PRT data, but the data entered was identical to the existing data. Therefore, the system recognizes that there is nothing new to save.
  Incorrect Data Entry: Sometimes, users may think they have made changes, but due to incorrect data entry or misunderstanding of the fields, the system does not register any changes.
  Authorization Issues: In some cases, the user may not have the necessary authorizations to make changes, leading to the system not processing the request as expected.
  
  
  Solution:
  
  Verify Changes: Double-check the PRT data
