[ic] overwriting existing item

[interchange-users@icdevgroup.org (Chaim Klar)]

HI:

In the IC admin area when I enter a new item with a sku # already
existing in my catalog it overwrites the old one.

Does anybody know of a quick fix that it should not overwrite the old
item; instead it should notify the user about the key violation.

Thank You
