• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION213 - Variables defined at project level cannot be changed; see long text ?

  The SAP error message CNV_DMC_MC_EXCEPTION213 indicates that there is an attempt to change variables that have been defined at the project level in the Data Migration Cockpit (DMC) or a related migration tool. This error typically arises during data migration processes when the system detects that certain project-level variables are being modified, which is not allowed.
  Cause:
  
  Project-Level Variables: The variables in question are defined at the project level, meaning they are intended to be consistent across the entire project. Changing them could lead to inconsistencies in the migration process.
