• Message number: 077

• Message text: Cannot delete - simulation versions exist

What causes this issue?

You cannot delete a WBS element, as long as it is part of an active
simulation version

How to fix this error?

Open the simulation versions, in which the WBS element is used, one
after another. In each version choose <ls>Simulation -> Administrative
data</> and set the <ls>Inactive</> indicator for each version.
You can now delete the WBS element.

• What is the cause and solution for SAP error message CJ077 - Cannot delete - simulation versions exist ?

  The SAP error message CJ077: Cannot delete - simulation versions exist typically occurs when you attempt to delete a project or a project version in SAP Project System (PS) that has associated simulation versions. Simulation versions are used to model different scenarios or changes without affecting the actual project data.
  Cause:
  The error arises because the system detects that there are simulation versions linked to the project or project version you are trying to delete. These simulation versions prevent the deletion to ensure that any potential data or scenarios modeled are not lost unintentionally.
  Solution:
  To resolve this error, you need to follow these steps:
  
  
  Identify Simulation Versions:
  
  Use transaction code CJ20N (Project Builder) or CJ03 (Display Project) to check if there are any simulation versions associated with the project.
  Navigate to the project and look for any simulation versions listed.
  
  
  
  Delete Simulation Versions:
  
  If you find simulation versions that are no longer needed, you can delete them. To do this:
  
  Go to the project in CJ20N.
  Select the simulation version you want to delete.
  Use the option to delete the simulation version (usually found in the menu or context menu).
  
  
  Ensure that you have the necessary authorizations to delete these versions.
  
  
  
  Retry Deletion:
  
  After deleting the simulation versions, attempt to delete the original project or project version again.

  Documentation: Refer to SAP Help documentation for Project System for more detailed information on managing projects and simulation versions.
  
  
  Authorization: Ensure that you have the necessary authorizations to delete projects and simulation versions. If you do not have the required permissions, contact your SAP administrator.
  
  
  Backup: Before deleting any versions, consider backing up any important data or configurations to prevent accidental loss of critical information.
  
  
  By following these steps, you should be able to resolve the CJ077 error and successfully delete the project or project version.
