Has this been solved yet? I am currently having techs being prompted to re calculate pricing after it gets into the invoice and it's changing the pricing on the customer. Luckily my techs have been on top of it but I have to go in and change ever invoice because it scrambles the Add On's around.
@blutz I would partner with your CSM (since they'll have to enable the Dynamic Pricing configuration anyway). Once enabled you can turn off permissions for editing prices and editing invoices and test to see if Dynamic Pricing overrides those permissions. I wish I knew but I can't find any resources on that yet!
