Hello Jason,

A TIBOQuery hooked up to a Table with a Required Field AAAA

and a BeforePost Event to set this Field, upon Append comes

gives the Error and Abort Message 'Field AAAA Must have a value'.

Tracing it shows it starts the Required Field test before

the BeforePost Event.

Might that be a problem and do You wish a Test Example ?

Best Regards,
Hans
