Bex Query generated code hack

Hi SDN,

Is it possible to manipulate characteristic values based on the key figure values in BEX Query output. Is that hack possible to control the query generated code at all?..

per say i have query out put like this (in a very simplified version)

Material customer Quantity customer_pcount

M1 C1 100 1

M2 C2 150 0

when customer_pcount = 0 related customer value need to be blank.

Out put should look like this:

Material customer Quantity customer_pcount

M1 C1 100 1

M2 150 0

thanks
