Calculation at run time

Hello,

I have a udf at row level which picks numeric value fro item master.

Now on delivery doc, say if i have two or three items with different values in this udf, is it possible to get sum in a different udf at title level?

What should be the udf type at title level? Will this have an impact?

ex. Item 1 row Udf1-> 5.00

Item 2 row Udf1-> 5.00

result in Title udf-> 10.00

Rgds,

RR
