• What is the cause and solution for SAP error message PPEACT121 - Only the first setup activity under &1 &2 can have a setup group ?

  The SAP error message PPEACT121 indicates that there is an issue with the setup activities in a production planning or process order context. Specifically, it states that only the first setup activity under a particular operation (identified by &1 and &2) can have a setup group assigned to it. This is a validation rule in SAP to ensure that setup groups are used correctly in the context of production planning.
  Cause:
  The error typically arises when:
  
  You have defined multiple setup activities for a single operation, and more than one of these activities has been assigned a setup group.
  The system is designed to allow only the first setup activity to have a setup group, as subsequent activities are expected to be part of the same setup and do not require separate setup groups.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Setup Activities: Go to the operation in question and review the setup activities defined. Ensure that only the first setup activity has a setup group assigned.
  
  
  Adjust Setup Groups:
  
  If you have multiple setup activities, remove the setup group from all but the first setup activity.
  If necessary, you can create a new setup activity that is intended to be the first one and assign the setup group to it.
  
  
  
  Check Configuration: Ensure that your configuration settings for setup groups and activities are aligned with your production process requirements.
  
  
  Testing: After making the adjustments, test the changes by trying to save or process the order again to ensure that the error no longer appears.
  
  
  Related Information:
  
  SAP Documentation: Refer to the SAP Help Portal or your organization's SAP documentation for more details on setup groups and production planning.
  Transaction Codes: You may need to use transaction codes like CO02 (Change Production Order) or COR1 (Create Process Order) to access and modify the relevant production orders.
  User Exits or BAdIs: If your organization has custom logic implemented, check for any user exits or BAdIs that might affect how setup groups are handled.
  
  If the issue persists after following these steps, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
