Document XXXXX does not contain any selectable items - during GR. REg.

Hi,

     I have created a PO while doing GR i am getting the following error."Document 4500000187   does not contain any selectable items". If I try with other user id the GR process is hapenning fine. But it is blocked for my user id. I hope the following information will be helpful for this.

I have rated a work flow under which if any body creates PO i am authorised to release the PO. the workflow is working fine I am able to release the PO of others. But if i create I am unable to do the GR process

Please help me out.

Regards
