• What is the cause and solution for SAP error message CN844 - Company code activity & and WBS element & are not identical ?

  The SAP error message CN844 indicates that there is a mismatch between the company code associated with a particular activity and the WBS (Work Breakdown Structure) element in a project. This error typically arises when you are trying to assign costs or perform transactions that involve both the activity and the WBS element, but they belong to different company codes.
  Cause:
  
  Different Company Codes: The most common cause of this error is that the activity and the WBS element are defined in different company codes. Each company code in SAP is treated as a separate legal entity, and transactions involving different company codes cannot be processed together.
  Incorrect Configuration: There may be configuration issues in the project system or the controlling module that lead to this mismatch.
  Data Entry Errors: Manual entry errors when assigning activities or WBS elements can also lead to this issue.
  
  Solution:
  
  
  Verify Company Codes: Check the company code assigned to both the activity and the WBS element. Ensure that they are the same. You can do this by navigating to the relevant transaction codes:
  
  For WBS elements, use transaction code CJ03 (Display WBS Element).
  For activities, use transaction code CJ20N (Project Builder) or CJR2 (Display Activity).
  
  
  
  Change Company Code: If you find that they are indeed different, you will need to either:
  
  Change the company code of the activity or WBS element to match the other.
  Create a new activity or WBS element in the correct company code if changing is not feasible.
  
  
  
  Check Project Structure: Ensure that the project structure is correctly set up and that all elements are aligned under the same company code.
  
  
  Consult Configuration: If the issue persists, consult with your SAP configuration team to ensure that the project system settings are correctly configured to allow for the intended transactions.
  
  
  Review Authorization: Ensure that you have the necessary authorizations to perform the actions you are attempting, as sometimes authorization issues can lead to misleading error messages.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ01 (Create WBS), CJ02 (Change WBS), CJ03 (Display WBS), CJR2 (Display Activity), and CJ20N (Project Builder).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Review SAP documentation on project systems and controlling to understand how company codes interact with WBS elements and activities.
  
  By following these steps, you should be able to resolve the CN844 error and ensure that your project activities and WBS elements are correctly aligned within the same company code.
