What do you mean by ‘member of child object record’?

means B.user__c = running user

This is doable in Skuid.

First you need to set up a condition that limits records to those created in the last 90 days. It looks like that is required on both paths.

Second, set up a condition that limits records to those owned by the current user.

The third part is tricky. You can’t just do a subquery condition and then include it in an or statement (with 2) Salesforce will yell at you. So you need to create a second model (put it above your first model). It needs to filter all the children records to those owned by the current user. (You might also be able to reduce that model volume by adding a second condition that limits it to records whose parent was created in the last 90 days). This model also needs to have the parentId as a field.

Then go back to your first model and add a third condition that filters record ID’s to those IN the list of Parent ID’s from the second model. See this condition below - where I’m trying to filter Accounts to those where the Opportunity Child record is owned by the running user.

Finally you tie these together with Grouping Logic so that records are retrieve when they meet conditions 1 and (2 or 3).

That should take care of things.

thanks Rob. the sequence of models was the issue. thanks again.
