I have a database that tracks inventory. There is a linked “Historical location” field that I would like to update every time the item moves to a new room ( i have a separate rooms table). I’ve read through forum posts and tried a few things. I gather that I need to map the existing linked field array and then add to it. Or somehow determine how many items are already linked and then add the new one. Any help is appreciated.
Example:
Inventory #1234 Historical Location: room1, room5
----Item moves to room15----
----update historical inventory with that new room ----
Inventory #1234: Historical location: room1, room5, room15
