I’m going to try to simplify my issue as much as possible. Hopefully it will be clear enough.
I have 2 bases : Operations & Purchases.
In Opérations I have a table with all my Orders.
In Purchases I have a table with all my Suppliers.
The Suppliers table is sync to the Operation base, and then my Orders’s records are link to the Suppliers still in my Operation base.
When I create a new Order I add the related Suppliers.
So on my Suppliers table in the Operation base I have for each supplier the listing of all the related orders as linked records.
Now I would like to have this same listing back in the Suppliers table, but in the Purchases base. And not as text field, but as linked records as well.
