bapi_goddsmvt_create

hello all!

i am trying to run this bapi through a test program.

i am trying to post movement type '311', with code = '04'.

i am getting an error that i cant overcome it, that the material, plant and storage location does not exist.

it comes from the fm good_movement_item_create

because its trying to find a record in table mard,

and cant find it.

what might be the problem?
