This error typically arises when there is an attempt to access or manipulate batch data in SAP, and the identifiers used do not correspond correctly.
  Cause:
  
  
  Key Mismatch: The primary cause of this error is that the batch key (Batch ID) and the batch class key (Batch Class ID) do not match. This can happen if:
  
  The batch ID being referenced does not belong to the specified batch class.
  There is a data entry error where the wrong batch ID or batch class ID is being used.
  The batch has been deleted or is inactive.
  
  
  
  Data Consistency Issues: There may be inconsistencies in the data stored in the database, such as missing or incorrect entries in the batch or batch class tables.
  
  
  Configuration Issues: Incorrect configuration in the system regarding batch management or OData service definitions can also lead to this error.
  
  
  Solution:
  
  
  Verify Batch and Batch Class:

  Use transaction codes like MSC2 (Change Batch) or MSC3 (Display Batch) to verify the details of the batch and its associated class.
  
  
  
  Check Data Consistency:
  
  Ensure that the batch exists and is active. If the batch has been deleted or is inactive, you will need to use a valid batch.
  Check the configuration of batch management in the system to ensure that it is set up correctly.
  
  
  
  Review OData Service:
  
  If you are developing or using a custom OData service, review the service implementation to ensure that it correctly handles batch and batch class relationships.
