CP427 - Details

• The SAP error message CP427 indicates that there is a mismatch between the company codes of a task list and a reference operation set. This typically occurs in the context of production planning and control, where task lists (which define the operations and sequences for manufacturing) and reference operation sets (which are used to standardize operations across different production processes) are expected to belong to the same company code.
  
  Cause:
  
  Different Company Codes: The most common cause of this error is that the task list and the reference operation set are created or assigned to different company codes. In SAP, each company code is treated as a separate legal entity, and certain objects must be consistent within the same company code.
  Incorrect Configuration: There may be a configuration issue where the task list or reference operation set was incorrectly assigned to a company code.
  Data Migration Issues: If data was migrated from another system
