Hi all, I inherited a FM file with a table with owners and a linked by IDkey vehicle table. Linked to the vehicle table are several other tables like maintenance, accessories etc. All made in FM4, now converted to FM11 (and still working). I have to add a functionality so that a 'vehicle' can change from 'owner'. What is the best (easy) way to do this, without losing the history of the linked tables on maintenance etc? Now I have zkp_customerID and zkf_vehicleID as key fields. Is it safe to just add a second vehicleID value to the zkf_vehicleID and make a sort of multi-key value of it, return separated? Or will I work myself in a corner. I was thinking to just add a second, or several, vehicle key values to the zkf_vehicleID by script.... Solutions appreciated. Tx
