E26 253 Error while check in only while running FM

Dear Experts,

I am trying to run Function module BAPI_DOCUMENT_CHECKIN2, which is returning with the error message E 26 253 Error while check in and storing: D:\ XXX (Path) \XXX (file name). I have entered the following required input.

DOCUMENT DATA:

DOCUMENTTYPE :

DOCUMENTNUMBER :

DOCUMENTPART :

DOCUMENTVERSION :

PF_HTTP_DEST : SAPHTTP

PF_FTP_DEST : SAPFTP

DOCUMENT FILES:

DOCUMENTTYPE

DOCUMENTNUMBER

DOCUMENTPART

DOCUMENTVERSION

STORAGECATEGORY : DMS_C1_ST

WSAPPLICATION : PDF

DOCPATH D:\Path name

DOCFILE : File Name

Surprisingly I can check in the document in the transaction(CV01/02), it is not giving any error message.

I have tried using the other Function module, BAPI_DOCUMENT_CREATE2. I can create the document, but when I try to Check-In it gives me a error message.

I have checked the RFC connection and it is working fine. There is no authorisation issue involved as well.

I hope I have explained myself clearly.

Thanks and Regards

Vinay
