Mass Upload using Store business document in Equipment Master

Hi ABAPER's,

Is there any any FM to upload pdf documents in background via store business document(GOS) in Equipment master(IE03)? At present user is attaching documents using Generic Object Services -> Create -> Store business document. But at a time only a single document can be uploaded. We want to upload an excel file where equipment number and file names are provided, By executing this new program, we need to upload all the documents directly into GOS. Any inputs are highly appreciated.

Regards,

Sibin
