Helen,

Many thanks for your help.
I've been reading and testing several aspects of locking and
master-detail with IBO in the last weeks. I used to work with
interbase and the BDE and other library called FreeIB. In both cases I
put the master table in edit mode when I accessed the lines. I am
learning IBO and other techniques to find better ways to do this.

Following your words:

I need to check that again, probably this three properties are not
correctly set-up and that's why I'm getting puzzling results.

I thought I should put some reference in keylinks in order the lines
locked the corresponding master. After reading your e-mail I
understand that everything should work automatically if all the
master-detail properties are correctly assigned. I'm going to check
that.

Let me analyse what you have told me and probably I should find the
solution.

Thanks again,
nice regards, _______________________________________________________
