Hmm, only way I can think of doing this is when you create the individual twbx files, you first amend the data extract in your data connection. When you perform a data extract, you can specify filters on the source using the popup menu -- so create one using Region = North, then save twbx, then edit the extract so that Region = East and create another twbx etc etc. The underlying data will only have the regional specific data in it.
Then revert your master .twb back to using all data to upload to the server.
Thank you. It accurately matches to my requirement.
But here we have several(around 15) related views so, can use one view
to filter among all other views to reduce time by not extracting
every view with filters.
