• What is the cause and solution for SAP error message CNVMBT371 - Subproject &1 still exist. ?

  The SAP error message CNVMBT371 indicates that a subproject still exists in the system, which is preventing certain operations from being completed. This error typically arises during data migration or project management activities within the SAP system, particularly when using the SAP Migration Cockpit or similar tools.
  Cause:
  The error occurs when there are still active subprojects associated with a main project that you are trying to delete or modify. This can happen if:
  
  Subprojects have not been properly closed or deleted.
  There are dependencies or references to the subprojects that need to be resolved first.
  The system is enforcing integrity constraints that prevent the deletion of the main project while subprojects exist.
  
  Solution:
  To resolve the CNVMBT371 error, you can follow these steps:
  
  
  Identify Active Subprojects:
  
  Use transaction codes like CN41 (Project Structure) or CJ20N (Project Builder) to list all subprojects associated with the main project.
  
  
  
  Review Subproject Status:
  
  Check the status of each subproject. If they are still active or in a state that prevents deletion, you will need to address this.
  
  
  
  Close or Delete Subprojects:
  
  If the subprojects are no longer needed, you can delete them using the appropriate transaction (e.g., CJ02 for changing projects).
  If they are still needed, ensure that they are properly closed or completed.
  
  
  
  Check Dependencies:
  
  Ensure that there are no dependencies or references to the subprojects that would prevent their deletion. This may involve checking for assigned resources, costs, or other linked objects.
  
  
  
  Re-attempt the Operation:
  
  Once all subprojects are either closed or deleted, re-attempt the operation that triggered the error.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N, CJ02, CN41, and CNVMBT for managing projects and subprojects.
  Documentation: Refer to SAP documentation or help guides related to project management and data migration for more detailed instructions.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions for this specific error message.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP Basis or technical team for further investigation, as there may be underlying system issues or configurations that need to be addressed.
