• What is the cause and solution for SAP error message /S4PPM/HIERARCHY010 - A work package cannot have the same external ID as the project ?

  The SAP error message /S4PPM/HIERARCHY010 indicates that there is a conflict with the external ID of a work package in relation to the project it is associated with. Specifically, this error occurs when a work package is being created or modified, and its external ID is the same as that of the project it belongs to. In SAP Project and Portfolio Management (PPM), each project and work package must have unique external IDs to avoid confusion and ensure proper tracking and reporting.
  Cause:
  
  Duplicate External ID: The primary cause of this error is that the external ID assigned to the work package is identical to the external ID of the project.
  Data Entry Error: This can happen due to manual data entry errors where the same ID is mistakenly assigned to both the project and the work package.
  System Configuration: In some cases, system settings or configurations may lead to this issue if they do not enforce unique external IDs properly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check External IDs: Verify the external ID of the project and the work package. Ensure that they are different.
  
  Navigate to the project in question and check its external ID.
  Check the work package that is causing the error and see what external ID is assigned to it.
  
  
  
  Change the Work Package External ID: If the work package has the same external ID as the project, you will need to change the external ID of the work package to a unique value.
  
  Go to the work package details and edit the external ID field.
  Assign a new, unique external ID that does not conflict with the project’s external ID.
  
  
  
  Save Changes: After making the necessary changes, save the work package and try to proceed with your operations again.
  
  
  Review System Configuration: If this issue occurs frequently, consider reviewing the system configuration to ensure that there are checks in place to prevent duplicate external IDs from being assigned.
