The Inserted (and Deleted) tables only exist inside a Trigger - not a Stored Procedure.
I'm assuming that there are actual Triggers created for tables which then call this stored procedure. Is that correct?
Assuming that it is, I don't see why you need the Inserted table in this procedure, since you already have the Key1 value.
Try taking out the Inserted table from this procedure and see if that works.
