Helen,

Thank you very much for the detailed explanation.

What is still a misterious for me is why it is not possible to insert
records in the BasicTutorial6. You allways get a "SYS_CHG_USER" is a
required value. If set this value in the DefaultValues property it
works. I did not see any difference between the definition
of "SYS_CHG_USER" and "SYS_CHG_DATE". Why does the one work and the
other not ?

BTW the default of "SYS_CHG_USER" is 'USER'. How to set this via
DefaultValues ?

Thank's again fro your help.

Regards,
Frank.
