How to link between custom PO Output for Communication output to be dispaly from Inquire --> View Do

Hi ,

As per standard process, for approved PO, I can run standard program 'PO Output for Communication' and see output.

Same output we can see by connecting to 'Inquire --> View Document' options from PO Summary Form.

As per our business requirement , we are runnig custom program 'BIC PO Output for Communication' to see output,same

output we used to see from 'Inquire --> View Document' options from PO Summary Form for same PO's. But now

due to some patch the link was missed here.

Need your help to built link as how it was there earlier ( or in standard case, how the link was built)
