BPM 4GL code to read an unbound text box from ReportQty screen

Hello to all: I am trying to setup a BPM using 4GL code to reference a text box added to the ReportQty screen (MES).

I would like to assign the value entered by the user in the text box (txtEpiCustom1) on the ReportQty screen to a variable where I will then re-assign it to a UD field in another table.

The text box is currently unbound. It is NOT matched up with any table or field associated with ttReportQty.

I was hoping there was a way to grab this info because the MES ReportQty screen does NOT have any UD fields avaialble.

Thank in advance,

Dave Olender
