leaveLookup

This procedure is fired on leave of a lookup field and handles the situation when a value is manually entered rather than using the lookup key.

When this occurs, it must be determined whether the screen value has changed. If the screen value has changed, it must be verified whether the changed screen value is a valid record. If it is a valid record, the key value is reset to avoid using the lookup.

Location: lookup.p

Parameters: None
