• What is the cause and solution for SAP error message GA123 - Receivers CCtr/act. type cannot be mixed with other types of receivers ?

  The SAP error message GA123 ("Receivers CCtr/act. type cannot be mixed with other types of receivers") typically occurs in the context of controlling (CO) when you are trying to allocate costs or perform a settlement that involves different types of receivers in a single transaction. This error indicates that you are attempting to mix cost centers or activity types with other types of receivers, which is not allowed in certain transactions.
  Cause:
  
  Mixed Receiver Types: The primary cause of this error is that the transaction you are trying to execute involves multiple receiver types that are not compatible. For example, you might be trying to allocate costs to both cost centers and internal orders in the same allocation or settlement run.
  Configuration Issues: There may be configuration settings in the controlling area that restrict the mixing of different receiver types.
  Incorrect Transaction Data: The data being processed may have inconsistencies, such as incorrect assignment of receivers or incorrect settings in the allocation structure.
  
  Solution:
  
  Check Receiver Types: Review the allocation or settlement document to ensure that all receivers are of the same type. If you have cost centers, ensure that all receivers are cost centers, or if you have activity types, ensure that all receivers are activity types.
  Separate Transactions: If you need to allocate costs to different types of receivers, consider splitting the transactions into separate runs. For example, perform one allocation for cost centers and another for internal orders.
  Review Configuration: Check the configuration settings in the controlling area to ensure that they allow for the types of allocations you are trying to perform. You may need to consult with your SAP CO configuration team to adjust these settings if necessary.
  Data Validation: Validate the data being processed to ensure that there are no inconsistencies or errors in the assignment of receivers. This may involve checking master data for cost centers, internal orders, and other relevant objects.
