Can I change the price on price sheets?

Yes. The price on price sheets can be changed. A start date for the new price can be defined. It is important to note that there can only be one valid from date per price segment for one country segment. 
Note: The price change also applies to already existing subscriptions with this price sheet. Invoices will be adjusted for the next accounting period accordingly.
Price sheets within a product contract, however, cannot be changed.
