Add a table to PLD converted crystal report

Hello Experts,

I am trying to add a table OPCH to Vendor Liability Ageing report (This is a system PLD converted crystal report).

This report has OADM,OADP and PLD_ITEMS datasources. I need to add OPCH to this report. How can i link OPCH with PLD_ITEMS.

Do you guys have, any ideas how to link PLD_Items source or is it possible?

Any help will be appreciated.

Thanks,

Regards.
