is it possible to track changes from one refresh to the next?
We are using the web enterprise version and direct connect.
The data base we are connecting to is like a temporary file. data is added and removed on a daily basis. But we only want to refresh data weekly.
For comparison, you will need to save an archive of your data. This can be done each day while reloading the application, but will make your application really big
how would I set up an archive data? Can it be done automatically at each refresh?
Yes you can. You just need to do a store statement with date in it
LET vArchiveDate = Date(Today(1), 'DD-MMM-YYYY');
LET vToday = Num(Today(1));
Date($(vToday)) as ArchiveDate
STORE ArchiveTable into ArchiveTable_$(vArchiveDate).qvd;
You want to compare row by row?
You can export some main KPI´s to text files on each reload and load them on next load comparing the results
