Question regarding 2nd calculation of UDF/scripted line totals while still on Lines tab: my client has tasked me with a handful of calculated UDFs in SO Entry to display in the bottom-right section of the Lines tab, which I have started creating by way of Line UDF + Column Post-Validate to calculate for each line, and then a corresponding standard Header UDF to calculate ""totals from lines"". Those are working correctly so far, but then they need a few more UDFs that take those initial subtotals and add/multiply some more, and then display while still on the Lines tab. I can get these to work if I could place the fields on the Totals tab as a UI Scripted Event, but they want everything together on the Lines, even though some calculations have to occur before others. I hope my issue makes sense. Does anyone have some suggestions about how to make these work together without leaving the Lines tab? TIA!
