  The SAP error message CNVMBT007 indicates that there is a configuration issue in the data migration process, specifically related to the assignment of sender and receiver structures in the SAP system. This error occurs when more than one sender structure is assigned to a single receiver structure, which can lead to ambiguity in data mapping during the migration process.
  Cause:
  
  Multiple Assignments: The primary cause of this error is that multiple sender structures have been assigned to the same receiver structure in the migration configuration. This can happen due to incorrect configuration or oversight during the setup of the data migration project.
  Data Model Changes: Changes in the data model or structure definitions may lead to conflicts if the mappings are not updated accordingly.
  Incorrect Configuration: The configuration settings in the migration tool may not have been set up correctly, leading to overlapping assignments.

  Identify Conflicts:
  
  Identify all sender structures that are currently assigned to the specified receiver structure.
  Determine if these assignments are necessary or if they can be consolidated.
  
  
  
  Modify Assignments:
  
  If multiple sender structures are not needed for the same receiver structure, remove the unnecessary assignments.
  If all sender structures are required, consider creating a new receiver structure to accommodate them.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the configuration to ensure that the error is resolved and that data can be migrated without issues.
