I really appreciate your support, however I dont know where to insert that code - please excuse my complete ignorance on the tool.
So far I managed in Qlik Sense Desktop to:
1) read from MSSQL database from a view I created using ODBC
2) Play around with graphs, charts and stuff
3) Im a little bit concerned about record count because the system adds 90 records every 30 minutes -- I already have like 200k records, and keeps growing every day - thats why I asked for help on the incremental load.
