Change Update Interval of Collections
If you've ever wondered how to change the update interval of the GlobalCollections to a number lower than 1 hour, go into Attribute Editor, search for the GlobalCollection and change the '''dynamicUpdateInterval''' to the number of MINUTES you'd like.
Please be aware that OneClick will show 0 hours!!
As an alternative you could force the update by cli:
$VNMDIR/update action=0x100f6 mh=$COLLECTIONMH
