  The SAP error message /SAPAPO/RRP_ATP101 An ATP check is only possible in the active planning version 000 typically occurs in the Advanced Planning and Optimization (APO) module when a user attempts to perform an Available-to-Promise (ATP) check in a planning version that is not active. Here’s a breakdown of the cause, solution, and related information for this error:

  Activate the Planning Version:
  
  Go to the transaction code /SAPAPO/VER (or use the relevant menu path) to check the status of the planning versions.
  Ensure that the planning version you are trying to use is set as active. If it is not, you can activate it.
  
  
  
  Use the Correct Planning Version:
  
  Ensure that you are using the active planning version (usually version 000) for your ATP checks. If you need to use a different version, you may need to activate it first.
  
  
  
  Check User Authorizations:
  
  Verify that the user has the necessary authorizations to access the active planning version. This can be checked with your SAP security team.
  
  
  
  Review Configuration Settings:
  
  If the issue persists, review the configuration settings in the APO system to ensure that the planning versions are set up correctly. This may involve checking the settings in the SAP APO configuration.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on managing planning versions and ATP checks.
