Webi Report Converting all Nulls into zeros

Hello Experts,

I am making a webi report on top of a BEx query by using BICS connection. My webi report shows me zeros instead of NULL/Blank.

I have CKFs in my bex query when i run bex query in bex analyzer i am able to see some nulls/blanks there, but when i am making a webi report these nulls/blanks are appearing as zeros in webi .

BOBJ= 4.1

BW= 7.3

Any Help ?
