Scale factor for an info object

Dear all,

Bex Query Output is below format:

Plant  Material Vendor Actual lot Qty

A       XX         1           200

B       YY        2           300

Requirement is for each material some value will be assigned

Ex:  Material XX =0.1 So  200*0.1=20       Material YY=0.2  So 300*0.2=60

So Required output is

Plant  Material Vendor Actual lot Qty  

A       XX         1           20

B       YY        2           60

Where i need to maintain this scale factor for material info object so based on that Actual lot qty needs to be derived as above

awaiting for your favorable responses.

Regards,
