  The SAP error message CNV_DMC_MC_EXCEPTION038 indicates that there are modified outdated objects in the system during a data migration or conversion process. This typically occurs in the context of using the SAP Data Migration Cockpit (DMC) or during a system conversion or upgrade.
  Cause:
  The error arises when the system detects that certain objects (like tables, views, or other database objects) have been modified after they were originally defined in the migration or conversion project. This can happen due to:

  Outdated Objects: Objects that have been changed in the source system but not updated in the target system or migration project.
  Inconsistent Data Model: Changes in the data model that have not been reflected in the migration project.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify Modified Objects:

  Update Migration Project:
  
  If the modifications are valid and should be retained, update the migration project to reflect these changes.
  Ensure that the data model in the migration cockpit is consistent with the current state of the objects in the system.
