I have a working copy of one of my tables. I make some changes to the to the working table because I don't want to save the additions until save has been pressed but I can't get only the records added to the working table saving to the real table. I had a similar problem with deleting from the working table. And this is how I solved that:

set deleted off
select wkinvdetail
set order to manifestno
select invdetail
set relation to manifestno into wkinvdetail
locate
delete for !eof("wkinvdetail") ;
and deleted("wkinvdetail") ;
and !deleted("invdetail");
in invdetail
set relation to
tableupdate(.T.)

I think it would be something similar but can't figure it out.

TIA,
Tyler
