I have an app that has a historical aspect and a current aspect to it. That is, I have my data coming in in a way that the new data is appended to the old data, and the way to tell the difference is the upload date. This data comes in every quarter.
I want to pull in data to the current aspect by making it so qlik only shows the values with the most recent date in the system. How can I get qlik to do this?
first, get the latest record from the table using Max function and next assign this value to variable and use this variable to qlik load. this will restrict the load and source only the latest values available in the dataset.
Cannot do. The app also needs all the older data for the historical parts of it. I need a way to selectively do this without limiting the qlik load globally.
ok, i understand that you do not want to apply a filter to the qlik load globally, yo want to apply some kind of filter on a qlik visualization so that you see data for most recent update ?
Yes, that would be ideal. I am thinking a master item would work for something like this. Do you have an idea of how I can write an expression that could achieve this?
Using set analysis you can create a measure which will give you the latest records. for e.g. i want to know sum of sales for today, then i write an expression sum({<Sales_Date={'$(=Date(today(),'DD/MM/YYYY'))'}>}Amount), this expression will give me sum of sales for todays date. you will need to write an expression in your measure.
