Compare data of excel and universe query

Hi Experts,

I am having 2 data provider in webi, one is from universe query and other from excel. In excel we have one column called "Match-Key" and its description. Match-Key is built on concatenation of other columns in same excel.

In universe query I have same set of columns using which "Match-key" can be created in this side.

What I need is to compare Match-Key of univ. query with excel Match-Key and keep data of universe query where universe_query Match-Key is matching with excel Match-Key.

Also show the Description of Match-Key from excel in report whose Match-Keys are matched.

I have created universe_query Match-Key using variable. Created one another variable where I have given following formula:

Check_key = If(Excel.Match-Key = Univquery.Match-Key;1;0) and given filter in report Check_key = 1.

But it is doing nothing in report. Data remains same in report.

Please guide me to come over the issue.

Data are:

Thanks and Regards,
