How To Fix PSHLP_MSG_CL121 - Simulation version of the current object (or its subobjects) exists

SAP Error Message - Details

• Message type: E = Error

• Message class: PSHLP_MSG_CL - Message Class for PS EhP4 Developments

• Message number: 121

• Message text: Simulation version of the current object (or its subobjects) exists

What causes this issue?

Active simulation versions of the current object (or at least of its
subobjects) exist in the system.
<ZH>Note</>
Changing the operative project does not affect the simulation versions.
If you transfer a simulation version to the operative version, however,
the system overwrites the changes to the operative object.

System Response

The system allows you to change the operative object.

How to fix this error?

If you want to change the operative object, you must change a simulation
version and then transfer this version to the operative object.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message PSHLP_MSG_CL121 - Simulation version of the current object (or its subobjects) exists ?

  The SAP error message PSHLP_MSG_CL121 indicates that a simulation version of the current object (or its subobjects) already exists in the system. This typically occurs in the context of project management or planning scenarios where simulation versions are used to analyze different scenarios without affecting the actual data.
  Cause:
  The error is triggered when you attempt to create a new simulation version for an object (like a project or a plan) that already has an existing simulation version. This is a safeguard to prevent the creation of multiple simulation versions for the same object, which could lead to confusion and data integrity issues.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Simulation Versions:
  
  Navigate to the relevant transaction or application where you are working (e.g., Project System, Planning).
  Look for existing simulation versions associated with the object in question. You can usually find this in the version management or version overview section.
  
  
  
  Delete or Modify Existing Simulation Version:
  
  If the existing simulation version is no longer needed, you can delete it. Ensure that you have the necessary authorizations to perform this action.
  If you need to keep the existing version, consider modifying it instead of creating a new one.
  
  
  
  Use a Different Object or Version:
  
  If you need to create a new simulation version for analysis, consider using a different object or a different version of the current object if applicable.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources specific to the module you are working with for more detailed instructions on managing simulation versions.
  
  
  
  Contact Support:
  
  If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes that deal with version management in your specific SAP module (e.g., CJ20N for Project Management).
  User Authorizations: Ensure that you have the necessary authorizations to view and manage simulation versions.
  Best Practices: Establish best practices for managing simulation versions in your organization to avoid similar issues in the future.
  
  By following these steps, you should be able to address the PSHLP_MSG_CL121 error effectively.
