Hi,
Thank you for reply.
Then do you have any suggestions?

I plan to set lAutoPrimaryKey = .F., create a uniqueID BizObj class, then retrieve the ID value without increase it kBizObj.OnNew()(For display purposes). Then, call loDataAccess.GeneratePrimaryKey() during kBizObj.save(). Do you think is is worth? BTW, I don't see any hook that allow me to do this, since PreSaveHook() is not in BEGIN TRANSACTION scope. Any ideas?

Thank you
