Cross updating records using lookup tables
Posted on 2013-01-08
Completely new to Access, trying to build an app for management of some company assets. Currently, just a simple setup utilizing the assets template from Access. Two tables right now, one for Vans, and another for Technicians. Using lookups, (even though I have read that it's not recommended practice?) it does seem to work... almost. If I create a van record, using the technician lookup, it will create the proper van record with Van Number and Tech Number, but of course in the tech table, Van Number is still a null value. I'd like them both to be updated when creating and editing records.
I was thinking about trying to make a logic for "After Update" or maybe even within the table itself, to do a cross update?
I am also wondering if this is attacking the problem in the wrong way. Should I not be using lookups and instead, figuring out how to create queries and macros? I need to ensure there's no duplicate data, there will be vans without techs, and techs without vans, but never a tech in 2 vans, for instance.
