Fixed Charge in Addition to Per-unit Merchandise Rate

Q: I have a Merchandise Rate that's per-liter for propane (the Rate has "Ask for other quantity" selected), but I also need to automatically add a single HazMat fee (flat rate).  Can that be done?

A: What you can do is add a 2nd Charge transaction to the same Rate definition that has the per-liter charge.  For the HazMat Fee, enter the equal sign ("=", no quotes) in the Qty field and press Enter.  That will open an Expression Creator for an expression to override the normal Qty.  Just enter the number "1" for the expression (no quotes) and Save.  Of course enter the Category, Description, and Each amount for the transaction as usual.

Now when you add the per-liter charge it will add the HazMat fee with a Qty of 1 no matter how many liters it is.

For reference, this is explained under "Using Calculated Expressions for Transaction Values" here:
