Issue with IDOC_WRITE_AND_START_INBOUND

Hi Experts,

I m using function module IDOC_WRITE_AND_START_INBOUND to create IDocs to post immediately. My partner profile is set up to process immediately. But I m getting the IDocs in status 64. When I m passing the parameter do_commit = 'X', I dont even see the idoc getting created, with this parameter being space, I get it in status 64. How can I get the IDocs to get posted in status 53? Any suggestions will be greatly appreciated.

Thanks a lot in advance!!

Anjana.
