problem with source report

[johny.cbi]

Source: Cube, Data Base: Oracle
there is sales amount in a cross Tab report (Target)
I created a Text item in the source report for sales amount
If I click on the the Source report sales amount text item, it is showing the sales (Target Report)
source report package is different and Target report package is different

Question?

Total sales amount which I got in the Target report, I want to put that sales amount number in the main
report. I couldn't see the Target report (Package) query items in Source Report (Package)

Is there any solution for this issue ?
