  The SAP error message CNV_DMC_MC069 indicates that there is a naming conflict at the subproject level in the Data Migration Cockpit (DMC) or during a data migration process. Specifically, it means that the name you are trying to use for a subproject already exists, and you need to choose a different name.
  Cause:
  
  Duplicate Subproject Name: The most common cause of this error is that you are attempting to create a new subproject with a name that is already in use by another subproject within the same project.
  Naming Conventions: There may be specific naming conventions or restrictions in place that you are not adhering to, leading to conflicts.
  
  Solution:
  
  Choose a Unique Name: The simplest solution is to select a different name for your subproject that does not conflict with existing names. Ensure that the new name is unique within the context of the project.
  Check Existing Subprojects: Review the list of existing subprojects to identify the names that are already in use. This can usually be done through the DMC interface or relevant transaction codes.
  Naming Guidelines: If there are specific naming conventions or guidelines provided by your organization or SAP, make sure to follow them to avoid future conflicts.
  Delete or Rename Existing Subproject: If the existing subproject is no longer needed, you may consider deleting it or renaming it to free up the name you want to use. However, be cautious with this approach as it may affect other processes or data.
