What is the proposed idea/solution? Update the roll-up field to return expandable linked record values when rolling up a linked record list How does this solve the user problems? The roll-up field currently returns comma-separated text when rolling up a linked record field/lookup. Unlike the lookup field which does return expandable records, roll-up fields can also remove duplicates using ARRAYUNIQUE(values). This is extremely useful when drilling up or down multiple levels of a linked record hierarchy because if any level has a one-to-many/many-to-many linked record relationship, duplication/redundancy will occur at the destination roll-up field (similarly with lookups). With ARRAYUNIQUE() and a roll-up field, users can remove this unwanted duplication BUT at the loss of expandable record links. The solution is to make the roll-up field return expandable records, just as the lookup field can. Some other benefits from this: adds the ability to group by rolled-up unique linked records in the timeline view using the split multi-selects group by option can quickly count distinct bottom-of-hierarchy items with top-of-hierarchy items using a count field How was this validated? Let's say we have the following hierarchy of linked tables: Departments <-(one-to-many)-> Teams <-(many-to-many)-> Projects ...and I want to know which projects involve each department via the Projects table's "teams involved" field. Approach A) In Departments, use a lookup field on the Teams table's linked record field to Projects this could yield unwanted duplicate project records in the lookup if two or more teams in the same department are involved with the same project. - not good Approach B) In Projects, use a lookup field on the Teams table's linked record field to Departments this could yield unwanted duplicate department records in the lookup if two or more teams involved with the same project are in the same department. - not good Approach C) In Departments, use a roll-up field on the Teams table's linked record field to Projects and use ARRAYUNIQUE(values) for the aggregation function this returns a comma-separated list, albeit with unique values - better, but not ideal Approach D) In Projects, use a roll-up field on the Teams table's linked record field to Departments and use ARRAYUNIQUE(values) for the aggregation function this returns a comma-separated list, albeit with unique values - better, but not ideal The solution is to make the roll-up field return expandable records, just as the lookup field can.
