Hi Abhi,
This is your sample data right.
Now create a variable
=If [Material] InList(100;200) Then "Tender Item"
Else If [Material] InList(300;400) Then "Normal Sales"
Else If [Material] InList(500;600) Then "Sample"
or simply
=If group inlist(100) then "Tender"
else if group inlist(300) then "Normal Sales"
else if group inlist(500) then "Sample".
---Add this column, apply break on it and perform Sum on Net Quantity.
Now hide Desc Column..
Finally your result will look like this.
Regards,
G Sujitha
