Portal Filter by match in a list

[nsdodgers]

Hello, 

I have a text field with a number of ID's separated by a carriage return and am in need of help creating a portal filter to return all of the child records that have IDs that are in the list of IDs.

 

I have been working on using pattern count to no avail. 

Thanks for the help!

Try:

not IsEmpty ( FilterValues ( Child::ID ; Parent::ListOfIDs ) )

Although I am not sure why you can't simply use the two fields as the match fields for the relationship.
