Infobject's Attribute as Query Filter

Hello Experts,

I'm creating report on top of the bex query, in bw have a infobject with few attributes in it. The requirememt is to create a filter using those attribute.

I tried to do in bex query but no luck, even in webi not able to bring them as query filter.

Please let me know is there any workaround to have attribute as filter in webi?

Appreciate your comments,

Note - using sp05 with patch level 1

Thanks,

Vinay
