John,

Thanks for the reply.

Q: Customer number is enabled and Customer name is disabled - why allow find a customer if the record is committed?

A: You've got a pretty odd structure here.
I know, this is just to illustrate how the Server property can affect the behaviour of the DEO.

Q: Why is date column enabled and val column disabled?

That's for the reason we already talked about. Date column is indexed so you can use it to find a different record.
Yes it is. As this is a child table and the DEO is a list of records IMHO still there is no reason to find records.

If you don't want to allow finds, the mechanism for disabling this, is the one presented earlier in this thread - make its field_index -1.
Thanks for providing a workaround. In fact, what I would like to do is disable the access of the field, not just finding.

I suppose that could be refined, but that's pretty minor.
OK, but end users get confused by typing on those columns and unable to save records. Solving it will help to prevent support questions from them.

Again, thanks for helping to clarify the issue.

Regards.
