When would you use Interval Match (extended) version over the normal Interval Match?

[jblomqvist]

Hello,

I am new to QlikView and I was reading about Interval Match extended.

Can anybody tell me when would you use Interval Match (extended) version over the normal Interval Match?

They don't look too different to each other so I would like to know when to use each one!

I have already read the Help and Reference Manuel but I still don't understand. Can anybody please simplify with an example?

Hi Swuehl yes your earlier linked helped as well as Manish's example. I am having more difficulty simplifying why key field has to be used to distinguish different ranges. What would happen if this wasn't the case?

Sorry if it sounds like a silly question, I am trying to really understand the importance of the key field

The really nice feature using QV is that's really easy to play around with samples.

Just copy the code from the HELP page and run the script, once with additional key and once without.

I believe there is nothing better than to actually see what happens.
