Error While "Check in" of a orignal in DIR

Hi All,

I am trying to attach the orignals to DIR's in SAP. These orignals are PDF files and they are located on a external shared network drive. I need to run this process in background as i need to upload around 60000 orignals. I am able to upload the orignal successfully with FM "BAPI_DOCUMENT_LOAD" in background mode. But now when i try to checkin the uploaded orignals with FM "CVAPI_DOC_CHECKIN", it gives me an error saying "Error While checking in and storing XXXX". Any clues in this would be very helpful.

Regards

Charitha
