Question
Why is there an additional discount being added to Renault Workshop Issues?
Answer
If there are additional discounts being added to the part see the below example.


See the discount is a -10.00 discount, however when using differing accounts, see this is adding an additional discount, which does not display in the discount box.
This discount, is set within:
Workshop > Parameters > Partner > Renault > Renault Warranty accounts
See against accounts you can set a Management Fee %. This will also then affect the discount when this is set against any chosen account.

If these are set this will add an additional discount.
