FI Documents posted cannot be seen..?

Gurus,

We are posting FI GL documents in the quality box using BAPI BAPI_ACC_DOCUMENT_POST and we are also using commit work after the BAPI...We ran it as a job and when we are monitoring it we see that documents are getting posted and it gives us the document number...But when we go to FB03 or to BKPF to see the document we cannot see...it says document does not exist...

What can be reason...Please suggest...its really URGENT...

Thanks

Sam
