I checked it out, and you are correct that the table isn't set up to accomodate the link between the QI Hist details and the QI item maintenance.

However, there should not be a need to make this link as all of the vital information in the item maintenance table (item code, item desc. and style code) is all kept in the QI Hist details table already. For example, if you are inserting the item name from the item maintenance table, delete it and reinsert it from the QI Hist table.
