Hi Vinita
Thanks for the reply. I think the validity option would work, but we would like to make some addresses invalid for some users, not all users. Making it invalid would hide it from all.
For the Exclude, we can't tick this at Root Node - it is always greyed out - which I think makes sense -include and exclude at the top of the tree is illogical. I tried Exclude at level 2, but standard system seems to always show every address in the Purchasing Org.
Regards
