  WXP775 Unexpected return (&1, &2) for FB CHECK_CUSTOMER_NAMES
  
  Cause:
  This warning message occurs during the execution of a Web Dynpro application or a related process where a function module or method CHECK_CUSTOMER_NAMES is called. The message indicates that the function module or method returned an unexpected return code or status, represented by the placeholders &1 and &2.
  
  &1 and &2 are variables in the message text that get replaced by actual return values or error codes at runtime.
  The function module CHECK_CUSTOMER_NAMES is typically used to validate customer names or related data.
  The unexpected return means that the function module did not behave as expected, possibly due to invalid input data, missing configuration, or a system inconsistency.
  
  
  Common Causes:
  
  Invalid or incomplete customer master data: The customer names or related fields might be missing or incorrectly maintained.
  Custom enhancements or user exits: If the function module is enhanced or replaced in a custom implementation, it might return unexpected values.
  System inconsistencies or missing authorizations: The user or process might lack necessary permissions to read or validate customer data.
  Incorrect parameters passed to the function module: The calling program might be passing wrong or incomplete parameters.
  
  
  Solution:
  
  
  Check the exact return values: Look at the actual values substituted for &1 and &2 in the error message to understand what unexpected return was received.
  
  
  Review customer master data: Verify that the customer names and related fields are correctly maintained in transaction XD03 or FD03.
  
  
  Debug the function module:  
  
  Use transaction SE37 to test CHECK_CUSTOMER_NAMES with the input data.
  If possible, debug the function module during the process to see why it returns unexpected values.
