Hi Sandeep,
I think there is some problem while passing Branch data from base report to target report. So try below.
In Preferences-> for WebI -> change to Interactive mode then you will be able to see what mallik shown to you.
1. In Base report: Select branch -> right click-> Select Hyperlink -> then a windows opens
i. Name
-> Browse to select the name of target report
ii.In Hyperlink properties
-> select refresh on open
iii.Document Prompts
-> select the branch object formula of base report in this prompt so that when the target report is called this branch value(s) are passed from Base to Target report.
2. In Target report the branch should have a prompt created and it is optional and this prompt is called while defining hyperlink in base report along with other prompts of target report.
