• What is the cause and solution for SAP error message AD018 - Values have already been saved ?

  The SAP error message AD018 ("Values have already been saved") typically occurs in the context of data entry or data processing within SAP systems, particularly when working with master data or transactional data. This error indicates that the system has detected that the values you are trying to save have already been saved in the database, and therefore, the operation cannot be completed as intended.
  Causes:
  
  Duplicate Entry: The most common cause is that the data you are trying to save is already present in the system. This can happen if the same transaction or master data record is being processed multiple times.
  Session Issues: If multiple sessions are open and the same data is being modified in different sessions, it can lead to conflicts and this error.
  Data Locking: If another user or process has locked the data you are trying to save, it may lead to this error.
  Program Logic: Custom programs or enhancements may have logic that prevents saving duplicate values, leading to this error.
  
  Solutions:
  
  Check for Duplicates: Before attempting to save, check if the data already exists in the system. You can do this by querying the relevant tables or using transaction codes that display the data.
  Refresh the Session: If you suspect that the session might be causing the issue, try refreshing the session or logging out and back in to see if the error persists.
  Review Lock Entries: Use transaction code SM12 to check for any lock entries that might be preventing the save operation. If you find locks that are no longer needed, you can delete them (with caution).
  Debugging: If the error is occurring in a custom program, you may need to debug the program to identify where the logic is failing or causing the error.
  Consult Documentation: Review any relevant documentation or notes related to the specific transaction or process you are working with, as there may be specific guidelines or restrictions.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), and SE37 (Function Module) to investigate the underlying data structures and logic.
  SAP Notes: Check SAP Notes for any known issues or patches related to the error message AD018. SAP frequently updates its knowledge base with solutions to common problems.
  User Permissions: Ensure that you have the necessary permissions to perform the operation you are attempting. Sometimes, lack of permissions can lead to unexpected errors.
