  The SAP error message RPM_INTEGRATION340, which states "Specified constraint is not allowed for summary task &1 in MS Project," typically occurs when there is an issue with the constraints set on a summary task in Microsoft Project (MS Project) that is being integrated with SAP.
  Cause:
  
  Constraint Type: Summary tasks in MS Project cannot have certain types of constraints applied to them. For example, constraints like "Must Start On" or "Must Finish On" are not valid for summary tasks because they are meant to summarize the tasks beneath them.

  Check Constraints: Open the project in MS Project and check the constraints applied to the summary task mentioned in the error message. Remove or change any invalid constraints to a valid type, such as "As Soon As Possible" or "As Late As Possible."
  Review Task Hierarchy: Ensure that the summary task is correctly set up to summarize the tasks below it without any conflicting constraints.
  Re-validate the Project: After making changes, re-validate the project in MS Project to ensure that there are no remaining issues.
  Integration Settings: Review the integration settings between SAP and MS Project to ensure that they are correctly configured to handle the project data.
  Consult Documentation: Refer to SAP and MS Project documentation for specific guidelines on constraints and integration best practices.
