• What is the cause and solution for SAP error message PPEACT627 - Only mode linkage is allowed between primary resources under &1 &2 ?

  The SAP error message PPEACT627 indicates that there is an issue with the configuration of primary resources in a production planning or capacity planning context. Specifically, it states that "Only mode linkage is allowed between primary resources under &1 &2." This typically occurs when there is an attempt to link primary resources in a way that is not permitted by the system's configuration.
  Cause:
  
  Incorrect Resource Configuration: The primary resources involved may not be configured correctly in the system. This can happen if the resources are set up to be linked in a manner that is not allowed (e.g., trying to link them in a way that is not mode-based).
  Resource Type Mismatch: The resources may be of different types or categories that do not allow for the type of linkage being attempted.
  Mode Linkage Requirement: The system requires that only mode linkages (where resources can operate in different modes) are allowed between primary resources, and the current configuration does not meet this requirement.
  
  Solution:
  
  Check Resource Configuration: Review the configuration of the primary resources involved. Ensure that they are set up correctly and that they are intended to be linked in the way you are attempting.
  Use Mode Linkage: If you need to link the resources, ensure that you are using mode linkage. This means that the resources should be configured to operate in different modes, and you should set up the linkage accordingly.
  Adjust Resource Types: If the resources are of different types, consider whether they can be adjusted to be compatible for linkage or if a different approach is needed.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on configuring primary resources and understanding the limitations of resource linkages.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as CR01 (Create Work Center), CR02 (Change Work Center), or CR03 (Display Work Center) to check and modify resource configurations.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on resource configuration.
  Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
