• What is the cause and solution for SAP error message /SAPAPO/CDPSCUSTOMIZ104 - The setup key is already being used in a setup group ?

  The SAP error message /SAPAPO/CDPSCUSTOMIZ104 indicates that there is an issue with the setup key being used in a setup group within the SAP Advanced Planning and Optimization (APO) module. This error typically arises when you attempt to assign a setup key to a setup group that is already in use by another setup group.
  Cause:
  
  Duplicate Setup Key: The setup key you are trying to assign is already associated with another setup group, which violates the uniqueness requirement for setup keys within the same planning area.
  Configuration Error: There may be a misconfiguration in the setup groups or setup keys in the APO system.
  Data Integrity Issues: There could be inconsistencies in the master data or configuration data that lead to this error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Setup Groups:
  
  Go to the transaction code /SAPAPO/CDPS1 (or the relevant transaction for your version) to view the existing setup groups.
  Identify the setup group that is currently using the setup key in question.
  
  
  
  Modify Setup Group:

  Change the setup key for the setup group you are trying to modify.
  Remove the setup key from the existing setup group if it is no longer needed.
  
  
  
  
  
  Create a New Setup Key:
  
  If the setup key is essential for both setup groups, consider creating a new setup key that can be used for one of the groups.
  
  
  
  Review Configuration:
  
  Ensure that the configuration for setup groups and keys is correct and that there are no unintended overlaps.
