• What is the cause and solution for SAP error message /SAPAPO/RRP_ATP108 - ATP check cannot be carried out until changes have been saved ?

  The SAP error message /SAPAPO/RRP_ATP108 indicates that an ATP (Available-to-Promise) check cannot be performed because there are unsaved changes in the planning environment. This typically occurs in the context of SAP Advanced Planning and Optimization (APO) when users attempt to perform an ATP check while there are pending changes that have not yet been saved.
  Cause:
  
  Unsaved Changes: The most common cause of this error is that the user has made changes to the planning data (such as changing quantities, dates, or other relevant fields) but has not saved those changes.
  Session State: The system may be in a state where it requires all changes to be saved before proceeding with the ATP check.
  Locking Mechanism: SAP uses a locking mechanism to ensure data integrity. If there are unsaved changes, the system may prevent further actions until those changes are committed.
  
  Solution:
  
  Save Changes: The immediate solution is to save any changes you have made in the planning environment. Look for a "Save" button or use the appropriate keyboard shortcut (usually Ctrl + S) to save your changes.
  Check for Errors: After saving, check if there are any error messages or warnings that need to be addressed before proceeding with the ATP check.
  Re-attempt ATP Check: Once the changes are saved, try to perform the ATP check again. The error should no longer appear if all changes have been successfully saved.
  Review User Permissions: Ensure that you have the necessary permissions to save changes in the system. If you do not have the required permissions, contact your system administrator.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP APO, such as /SAPAPO/RRP for planning board or /SAPAPO/ATP for ATP checks.
