Hi,
In Create invoice proposal, i have added custom field/form string control in the form name 'Bank' where the control have lookup for Bank Account table.

I want save the 'Bank' field value into ProjProposalJour when click OK button after select the project transaction lines.
The form data source using is tmptable, where the form method closeOk() execute the coding for creating the project invoice proposal record.
But still i cannot find the correct method to extend to accomplish my objective.
How can i save the 'Bank' field value directly to ProjProposalJour after click the OK button on the form?
Thanks in advance.

Afieq
