UDF at header level will not auto refresh before & after adding the invoice.

Hi All,

I have a FMS query in the UDF at AR Invoice header level. I have set the FMS query to auto refresh when tax rate field changes but the UDF doesn't auto refresh when there is a tax code in the document.

I will need to add the invoice first then open the added invoice and press shift+F2 to get the calculated amount in the UDF to update the invoice.

How to get the UDF to auto refresh whenever the tax code has changed? Or after the invoice has added?

The FMS query:

SELECT sum(T0.[TotalSumSy]) FROM INV1 T0 inner join OINV t1 on t1.docentry = t0.docentry WHERE T0.VatGroup in ('SR','DS','AJS') and t1.docentry = $[OINV.docentry]

Thanks & BR,

Leng
