Hi
Set deleted ON Specifies that commands which operate on records (including records in related tables) using a scope ignore records marked for deletion.

Some criptic comments therefore:-
option 1:- data source is ... for deleted() <> .t.
your co user will not see the record

option 2:-if you show a delete tag , like in a grid, it should show when co user moves onto that record

option 3:-If your delete operation , whicih is really a " mark record for deletion at a later time" includes
replace name with "Deleted"+"name" no mistakes or confusion.

option 4:- as above but just make record a blank record.
append procedure will be :-
search for blank and if found use , else appand blank


Note:
Hope this helps. The refreshing of changes on the network is very good in vfp but in my experience the user must move onto the record to show the change. It will not happen automatically.

Hope some help here and we geyt some more comments from other users.

Regards
Ryss
