I have to merge two Qlik view dashboards both with four tables in common and exclusive tables are also there in both dashboard.
Request you to kindly suggest the best way to merge the dashboard.
It will be very helpful for me to move further.
Tried to merge through binary load and fetching QVW one data model into another but getting the multiple tables in common and getting n number of synthetic keys.
Request you to please suggest on same.
