Limit One to Many Associations to 1 Record

Hi,

We have a One to Many relationship between two entities A and B.

In our application, there is a use case where we only want 1 record to be associated from A to B.

Is it possible to do this somehow? I.e., detect that a relation has already been made and then not allow more to be made from other entities?

Thanks - Greg.

Hi Greg.

Is this restriction on the records on the entity or on the entity itself?

1.Are you thinking that there is only one relationship between entity A and entity B?

2.Or is only one record on the entities allowed to be associated?

Or is it something else?

It's on the records themselves... there are some cases where we only want there to be 1 record selection allowed.
