Use variable of a one query in other query SAP BO

Dear All,

I am merging 3 queries created using Universe(which is created using BeX query) in SAP WebI Report.

Am using a CSF Input RSF Output Query Varible in Boiler Chemical Consuption Query formula

But am not getting value for the field Power Consuption:

But there are values for Power for RSF in same date

And there are values for RSF Output in Same date:

Why am not able to see any value in Power Consuption which i used variable RSF Output of first query. Should i do any other step to get the value.

Please help me in solving this issue.

Thanks & Regards,

Rithika.
