I have a type 3 form with 10 occurrences. I can change all ten occurrences and when I press the save button, I get error message 206 which states that the record is not locked on db.update.

Also, I can reexecute the session, reapply the same changes, press the save button and the system accepts the changes. No error message.

Can anyone explain this?

İf you use db.lock.table anywhere which related to your table, may be it caused. If you don't use Db.lock anywhere , I think that you must do reconfig your table.May be it may correct your operation.BUt I don't see your problem exactly

Good luck ...

Error 206 is mostly programming error . When working with main tables , Baan puts record level lock for modifications. So if u do other updates (on any table including main tablesthrough code during this modification time), this record locks gets lost and hence the error 206.

So u should other tables change either in before.rewrite / write section (without db.retry.point / commit.transaction) OR u do the same in after.update.db.commit section .
