hi friend,
When I choose PO no, vendor account and PO name should be populated in the form automatically its done.
If I choose vendor account in vendor field, I should have a lookup of PO no related to that vendor. by using lookup method i done it.
my problem is am not choosing a vendor account means the PO no displays the empty lookup . how can i check the Vendor Account Field is Select or not.Suppose select means display the related PO no for Vendor Account Look up otherwise It Should be Displays General Look up for All PO no,PO Name and Vendor Account Number .
How can I solve it…
