• What is the cause and solution for SAP error message CNVMBT008 - Receiver structure &1 has no sender structure assigned ?

  The SAP error message CNVMBT008 indicates that there is a problem with the mapping of data structures in a migration or data transfer process. Specifically, it means that the receiver structure (the target structure where data is supposed to be sent) does not have a corresponding sender structure (the source structure from which data is being sent) assigned to it.
  Cause:
  
  Missing Assignment: The most common cause is that the configuration for the data migration or transfer process is incomplete. The receiver structure has not been linked to a sender structure in the mapping configuration.
  Incorrect Configuration: There may be an error in the configuration settings where the sender and receiver structures are defined.
  Data Model Changes: Changes in the data model (e.g., changes in the source or target systems) may have led to the removal or alteration of the expected structures.
  
  Solution:
  
  
  Check Mapping Configuration:
  
  Go to the relevant transaction or tool where the mapping is defined (e.g., LSMW, SAP S/4HANA Migration Cockpit).
  Verify that the receiver structure is correctly assigned to a sender structure. If not, create or modify the mapping to ensure that the sender structure is linked to the receiver structure.
  
  
  
  Review Data Structures:
  
  Ensure that both the sender and receiver structures exist and are correctly defined in the system.
  Check for any recent changes in the data model that might have affected the structures.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or migration guides related to the specific migration or data transfer process you are using. This may provide insights into the expected configurations.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test run of the migration or data transfer process to ensure that the error is resolved.
  
  
  
  Seek Help from SAP Support:
