Group By And Sum W/o Codes and using Codes in REPORTS .....

Hello EveryOne,

i have a customised table in which there are 6 coloumns;

1- ItemID

2-InventColorID

3-InventSizeID

4-ConfigID

5-Warehouse

6-QTY

Now i want to make a report in which user can apply multiple filters from dialog Box like 1 or 2 or 3 warehouse (W1,W2,W3 etc) and itemID filters

now the report will do grouping on ItemId,InventColorID,InventSizeID and print the sum of (QTY) also

How is it possible with multiple filters?

i can easily do this thing with single only filters…??

kindly provide me logic
