Specifically, the error message states that the item category specified does not permit customers, and as a result, the customer in question is not included in the transaction.
  Cause:
  
  Item Category Configuration: The item category defined in the sales document may be configured in such a way that it does not allow for customer-specific data.

  Sales Document Type: The sales document type being used may not be compatible with the item category for the customer being processed.
  Customer Master Data: The customer master data may not be properly set up or may not be compatible with the item category being used.

  Check Item Category Configuration:

  Consult Documentation:
