Formula Help - Adding Case Field into Task

[PhotoMommie]

I'd like to be able to show another entity field on the list view for the Tasks. I KNOW that there is a formula to do this, but I am struggling. I thought that I could apply the:
activityMatter = case.clientMatter, but it will not link the parent to the case. Maximus Can you help work your magic on this for me again??? :-)

Hi,
you can make for Task some formula like this:

ifThen (
    parentType == 'Case',
    activityMatter = record\attribute('Case', parentId, 'clientMatter')
);

Maximus You are amazing! That formula did the trick!
