Unable to make changes to renewal order in Partner Portal after auto-renewal locked it

Issue:

Unable to change the products or license amounts of a renewal order in Partner Portal after auto-renewal locked it.

When on the Sales > Renewal Center the renewal opportunity is selected and Renew + Modification button is clicked, an error is shown that tells that the order has been locked and changes can no longer be made because there are less than 7 days left until the subscriptions will be renewed. 

Resolution:

The opt-out deadline for for auto-renewal is up to 7 days before end date, this means that the order cannot be cancelled when there are less than 7 days until the renewal date. You can still make changes to the quote when there are 6 days left before the renewal is set to happen. When there are less than 5 days, the order is placed and it is locked. 

To make changes to the quote when there are 6 days left, navigate to the Sales > Renewal Center page in the Partner Portal. Click on the customer's renewal opportunity in the Renewal Opportunity column and on the next page you can click on the quote which you want to modify. 

Edit the quote and then click Calculate -> Quick Save -> Save. Then confirm that the selected products, amounts and prices are as they should and then you can click Generate order.
