Inventory Report

Hi experts, in the report 10162 (Top Inventory item), I tried to add a new column (sales qty), but it does not work. If run for one item, it looks like the number is correct, but if it is more than one item, the numbers are not correct. Below is the code:

Create topitemqty variable and add this variable to the layout.

CALCFIELDS("Sales (Qty.)");
topitemqty[NextTopLineNo] := "Sales (Qty.)";

Thank you!
