Measure from lookup table

[akwang]

Hi I have two tables one is my fact tabe which has qty of items sold and another table which has the net weight for each product. I want to calculate the net weght of product sold by QTY * Net wgt. Currently I use the RELATED function to import from the lookup table to another column, but is their a better solution?

You could avoid using a calculated column with the following measure:

Net Weight Sold =
SUMX (
    tbl_SAP_Data,
    tbl_SAP_Data[Net Qty] * RELATED ( tbl_Prod_Description[Net Weight (g)] )
)

This measure will iterate over each row in the tbl_SAP_Data table.  In each row, it will multiple the [Net Qty] column by the appropriate [Net Weight (g)] column from your lookup table, thanks to using RELATED() within the row context created by iterating with SUMX.
