Webdynpro RFC call

Dear Experts,

I have a situation in which my RFC call from the webdynpro component is giving an error. I am using BAPI_BUPA_CREATE_FROM_DATA. When i execute this particular BAPI in se37 with a particular destination (that i need to give), it creates the Business Partner. But when this same RFC when i try to execute it in webdynpro with the same values it gives error. Plz help and suggest a solution.

Thanks and regards,

Ainesh.
