You can adjust prices on services. This is possible since services in G5 are parts with their own part type.
The price is now adjusted in the price unit, not always in the standard unit.
You can create new rows in the staggered price steps (own list type).
If you copy price from a price linked to the calculation log, then the new price will also get the same link.
If you change a price pointing to a record in the calculation log, the link will be broken. There is no reason to for example have a standard price of 100 SEK pointing to a calculation which gives the price 90 SEK.
