In my SYS Invoices module, I have a line item with the Applies To being the subset. Line item is formatted to Boolean with the formula being True.
When I exit the blueprint, since ss_Active: Invoices (the subset) is part of Invoices, it will show a check for the members that are in the subset
Also, doing it this way versus doing a finditem() is better for performance reasons.
Looking at your formula, it looks like the subset is on L4 but you are doing your finditem on L5. If this is correct and L5 rolls up to L4, then you will not be able to find it as the subset doesn't go down to L5. So, if L4 is a parent of L5 and the subset is on L4, then create a line item on L5 (formatted to L4) with the formula being: parent(item(L5)). Then you can do a lookup to the L4 subset: SYS L4.Subset?[lookup:the line item for parent of L5]
Thanks for the replies. I ended up changing the subset to a text field in the list and using a lookup to determine if the account was in the list set or not. I didnt want to create additional line items to be able to test or refer to the items. Then my filter was just if TRUE.
Just know, creating a filter like that is a huge performance hinderance because Anaplan does not read those 3 conditions at the same time, it reads them one at a time. Meaning, it reads the data for the first filter condition, then of that returned data, it does another read for the 2nd filter, then another read for the 3rd condition which is why that is against best practice (Planual Rule 4.03-06).
