Incremental Loading in QMC

[#1]

Hi Everyone,

I'm new in using Qlik. With regards to incremental loading, is QMC's Tasks (scheduled data loading) do the incremental loading automatically or should we include the incremental loading script in each of our Qlik App? Many Thanks.

Regards

Incremental Loads are usually done in a QVD Generator qvw app.  This app is then set up as a QMC Scheduled Task.

I usually have a QlikView app which does the incremental load and saves the latest data to a QVD file. This can be scheduled to run whenever you'd like.

Then other QV apps can (quickly) access the QVD file.

Great stuff guys. Is this the same case with Qlik Sense? I'm assuming it is

[Peter_Cammaert · Accepted solution]

Loading data incrementally is done entirely in a Load script which is part of every QlikView application (QVW). There are no predefined tools or tricks to do an incremental load (aside from the BUFFER prefix) which has a big advantage (unlimited flexibility) and an equally big disadvantage (you have to do it all by yourself). On the plus side, there are a massivme amount of documents-articles-discussions-examples-demo's-working documents available in this community that all implement incremental loads in some form or another. At least one of them will fit your needs.

A good place to start is Incremental Load in Qlikview - Sources

Just joking. Better start with this official Qlik presentation: Incremental Load Scenarios.pdf
