Susan, Yogi and other Ontarions struggling with this:

One of my clients has a similar issue with envro fees on paint. Like Susan suggests, they created a whole category of non-stock items for the fees. (the category code is the first segment in their item number, so they make the rest of the item code the same as the code for the item the fee applies to.

They use the Order entry History inquiry for Items; select the category and appropriate dates, and produce the detailed report which they can export to Excel.
