    You can see the further possible action right in exception message:

    Web service processing error; more details in the web service error log on provider side

    Contact web service provider's technical staff in order to get more info about received exception.

      we put external break point and checked , but first line of function module code itself not triggered.

      mean time we got the error screenshot (ST22) from BASIS team.

      please let me know if you have any clue.
