• What is the cause and solution for SAP error message RPM_INTEGRATION251 - Resource cannot be updated; MSPS is defined as the lead system ?

  The SAP error message RPM_INTEGRATION251 indicates that a resource cannot be updated because Microsoft Project Server (MSPS) is defined as the lead system in the integration between SAP and MSPS. This typically occurs in scenarios where SAP is integrated with MS Project for project management purposes, and the synchronization of data between the two systems is governed by specific rules.
  Cause:
  
  Lead System Configuration: The error arises when MS Project Server is set as the lead system for resource management. In this configuration, any updates to resources must be made in MS Project Server rather than in SAP.
  Data Synchronization Rules: The integration rules dictate that changes to resources should originate from the lead system (MSPS), and any attempt to update resources directly in SAP will trigger this error.
  Resource Locking: If a resource is currently being used or locked in MSPS, it may also prevent updates from being made in SAP.
  
  Solution:
  
  Update in MS Project Server: To resolve the error, you should make the necessary updates to the resource directly in Microsoft Project Server. Once the changes are made there, they should synchronize back to SAP.
  Check Integration Settings: Review the integration settings between SAP and MSPS to ensure that they are configured correctly. If you need to change the lead system, you may need to consult with your system administrator or IT department.
  Synchronization Process: Ensure that the synchronization process between SAP and MSPS is functioning correctly. If there are issues with the synchronization, they may need to be addressed to allow for proper updates.
  Consult Documentation: Refer to the integration documentation for SAP and MS Project Server for specific instructions on how to manage resources and the implications of having MSPS as the lead system.
  
  Related Information:
  
  Integration Scenarios: Understanding the integration scenarios between SAP and MS Project Server can help clarify how data flows between the two systems and the roles they play.
  User Permissions: Ensure that users have the appropriate permissions in both systems to make changes to resources.
  Error Logs: Check error logs in both SAP and MSPS for additional context or related errors that may provide further insight into the issue.
  Support Resources: If the issue persists, consider reaching out to SAP support or your organization's IT support team for assistance.
  
  By following these steps, you should be able to address the RPM_INTEGRATION251 error and ensure that resource updates are handled correctly within the defined lead system.
