How to prevent a user from entering characters into a number field
How do you prevent a user from entering characters like A or B into a field that is defined as a numeric field?
Please note that
- we use block validation (for other reasons)
- we are not able to convert these numeric fields to character fields
We want to avoid a user being hasseled with the FRM-40209 ... message.
This message is
- not very helpfull because it does not inform us what the problem field is
- not suppressable
Any hints ?
