Most of the time we use temporary fields and tables in our load scripts in Qlik.
Usually we have some sort of a naming convention like temp_TableName or TableName_temp.
I quite like the way a temp table is identified in SQL with a #-prefix, so I adopted this naming convention for my temp fields and tables in Qlik.
This brought with it a nice advantage in that all the #-fields and #-tables are listed at the top.
Now you can easily see if you have any temp fields and tables left in the app.
This got me thinking: if all my temp tables and fields follow a strict naming convention, I can identify and drop those at the end of my script easily, and not have to worry about them being left behind.
