How To Fix CJ028 - Simulations already exist for the WBS element

CJ028 - Overview

• Message type: E = Error

• Message class: CJ - Project master data and structure

• Message number: 028

• Message text: Simulations already exist for the WBS element

What causes this issue?

You want to change an operative WBS or sub-tree. Active simulations
already exist for this WBS element/these WBS elements. Changing the
operative network while simulations are active could lead to data
inconsistencies.

System Response

The system lets you make a change.

How to fix this error?

Make sure that you really want to change the operative WBS elements and
not the simulation version.

CJ028 - Details

• The SAP error message CJ028 ("Simulations already exist for the WBS element") typically occurs in the context of project management within SAP, particularly when dealing with Work Breakdown Structures (WBS) and project simulations. This error indicates that there are already existing simulations for the specified WBS element, which prevents the creation of new simulations.
  
  Cause:
  
  Existing Simulations: The primary cause of this error is that there are already simulations created for the WBS element you are trying to work with. SAP does not allow multiple simulations for the same WBS element to avoid confusion and data integrity issues.
  Incorrect WBS Element: You may be trying to create a simulation for a WBS element that is not intended for simulation or is incorrectly specified.
  System Configuration: There may be specific configurations or settings in your SAP system that restrict the creation of new simulations under certain conditions.
  
  
  Solution:
  
  Check Existing Simulations: Before attempting to create a new
