  The SAP error message CNVMBTCHECK011 indicates that there is a recursive structure definition in your data model. Specifically, the message states that a structure contains itself as a next structure, which is not allowed in SAP data definitions. This typically occurs in the context of data migration or conversion processes, particularly when using the SAP Migration Cockpit or similar tools.
  Cause:
  The error arises when a structure is defined in such a way that it references itself directly or indirectly. This can happen due to:

  Review Structure Definitions: Check the structure definitions in your migration project. Look for any structures that may be referencing themselves. This can often be found in the data mapping or transformation rules.

  Test Changes: After making the necessary corrections, test the migration process again to see if the error persists.
  
  
  Consult Documentation: If you are unsure about the structure definitions or how to correct them, refer to the SAP documentation or help resources related to the specific migration tool you are using.
