Is there a way to prevent duplication of data across 3 fields in 2 tables?
I have two tables:
tRequest
IDRequest (PK)
FIDAcademicYear (FK from tAcademicYear)
FIDRequestType (FK tRequestType)
FIDSubject (FK from tSubject)
RequestDate
FIDStaff (FK tStaff)
1:M to:
tRequestDetail
IDRequestDetail (PK)
FIDRequest (FK from tRequest)
FIDLocation (FK from tLocation)
FIDSoftwareItem (FK tVersion)
ConfigInfo
Is there anyway to prevent the following 3 fields from being the same?
Sorry, not sure where this should go, not sure if it's an event on a form or what...
Thanks! I keep asking questions and you lot have been so helpful with your time and advice. Maybe one day I can give something back here.

- tRequest.FIDAcademicYear
- tRequestDetail.Location
- tRequestDetail.SoftwareItem
