So for a Bit of Context;
I added a delivery tab in My app to show all upcoming ‘Container’ Deliveries.
Each ‘Container’ Contains Multiple ‘Pallets’, Each Pallet belongs to a different “Project”.
So I Created a lookup to Show the “Project” for all Related Results, and then a Join, for it to show up as a single line within the ‘Container’.
However, Now it shows up as “7871, 7871, 7369, 7871” Instead of my desired result; “7871, 7369”
so I ended up implementing a solution I know best.
I did a Unique formula in a separate sheet =UNIQUE( {Container# , ProjectName} ) which basically lists the Unique Containers and Projects,
then a relation to the Container # in that sheet
Lookup to the Project Name
Joined the Lookup
I did if for 2 reasons, 1. It’s more familiar territory, 2. Row ID might be an issue since the Containers sheet is an IMPORTRANGE.
as for performance, the Unique formula shouldn’t be too heavy and only updates when new containers are added, so it’s not too bad.
I’m wondering what your thoughts are on that.
I guess it depends what you’re using the RowID’s for.
In this case, the only important thing is that they remain unique - which they would, even if data is added or removed.
