Scenario as

I have make Three User defined fields in Production BOM Row Level as

U_QTYCOST -----> Type Units & Tools Structure Quantity

U_Percent       -----> Type Units & Tools Structure Quantity

Qty                 ----->

and i want to get Total Percentage in Qty Field.

i.e

120 + 15% = 138

120 +15/100*120=138

i have to set this in BOM Row level Qty Field

my work around

SELECT ($[T0.U_QTYCOST]+( ($[T0.U_Percent] /100) *$[T0.U_QTYCOST] ))FROM ITT1 T0
