• What is the cause and solution for SAP error message /SAPPCE/DPCM1143 - You can only assign one WBS element for each contract ?

  The SAP error message /SAPPCE/DPCM1143 indicates that you are trying to assign more than one Work Breakdown Structure (WBS) element to a contract, which is not allowed in the system. This restriction is typically in place to maintain the integrity of project accounting and ensure that each contract is linked to a single WBS element for tracking purposes.
  Cause:
  
  Multiple WBS Assignment: The primary cause of this error is that the system is configured to allow only one WBS element per contract, and an attempt is being made to assign multiple WBS elements.
  Incorrect Configuration: There may be a configuration issue in the project system settings that is not allowing the assignment as intended.
  Data Entry Error: The user may have inadvertently selected multiple WBS elements during the assignment process.
  
  Solution:
  
  Review Assignment: Check the contract and ensure that only one WBS element is assigned. If multiple WBS elements are selected, remove the additional ones and keep only the required WBS element.
  Check Configuration: If you believe that the business process requires multiple WBS elements, consult with your SAP administrator or project manager to review the configuration settings in the Project System (PS) module. They may need to adjust the settings or provide guidance on how to handle your specific scenario.
  Use Alternative Structures: If your business process requires tracking multiple WBS elements, consider using alternative structures such as creating sub-projects or using network activities that can be linked to the main contract.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on WBS and contract assignments.
  
  Related Information:
  
  SAP Project System (PS): Understanding how WBS elements function within the SAP Project System can help clarify why this restriction exists.
