I have a database that holds information regarding our contractors. Each contractor has a licence which allows them to work on specific types of aircraft and the level to which they are approved to work.
The current form works perfectly well to record the aircraft type and the approved level of competance, but I now need to add any limitations to the level, so for example:
B747-8 B1 1,3,6
B747-8 is the aircraft
B1 is the level of compentance
1,3,6 are the limitations to the level of compentance
There are 10 different limitations, each of which can be used seperately or in combination with each other:
1,2,3,5,6,7,9,10,11,XX
In addition, the limitations may be ammended or increased in the future.
How do I set up my tables and my form to allow both for the selection of several limitations in any combination and so that it can be easily ammended in the future?
I have tried using the multi select list box, which I know many purests don't like, but it doesn't work anyway - I have a split database and it causes the db to crash when I use a linked table as the source of the list box.
My current tables are:
tblContractors
tblLicence
tbl145Limitations
tbl145JUNC
tbl145Limitations has the limitation number and the description as records, rather than fields because that way they can be ammended in the future. But I can't work out how to then use them as fields in tblLicence.
I have also created tbl145JUNC as a junction table to allow a many to many relationship, but the above still applies.
This one is simply beyond my competance, so thank you for your combined expertise. Hopefully you can help me avoid spending more time tearing my hair out...
