In LCS, open the project that is associated with the implementation project.

At the top of the page, select the hamburger icon, and then select Subscription estimator .

Download the sample usage profile.

Answer the required questions on each tab. If you're a Commerce customer, be sure to answer the questions on the Retail and Commerce tab.

Save the usage profile locally.

To upload the usage profile, select New estimate , name the estimate, and then upload the usage profile.

After the upload is completed, select Mark as Active to activate an estimate. An active estimate is required in order to configure a production deployment.

When there is a valid active estimate, the Configure button becomes available. You can use this button to request a production environment deployment.

Edit the estimate for multiple implementation projects

To edit the estimate for multiple implementation projects, follow these steps.

Open the Subscription estimator tool for each implementation project.

Edit the active subscription estimate to apply the license allocation for each project. To edit a subscription estimate in the Subscription estimator tool, select it, and then select Edit estimate .

In the Edit estimate dialog box, enter the license count for each type of finance and operations license. By default, when every subscription estimate is created, the full count of all purchased licenses is assigned to it. Customers can't allocate more than the total number of licenses to a single estimate. Additionally, they can't reduce the allocated number so that it's less than the minimum number that the Dynamics 365 Licensing policy requires.

Select Save .

A message box warns you that updates to an active estimate might cause the size of your production environment to change. Select Yes to confirm that you want to continue with the update.

Although you can have multiple estimates, one estimate must be marked as Active . After the production environment has been deployed, or after deployment of the environment has received sign-off, the active estimate is locked. If you make any additional changes to the active estimate or mark a new estimate as Active , you might cause the production environment to be resized.

Frequently asked questions

Why isn't the Configure button for deploying a production environment available, even though there is an active estimate? And why does a warning message appear in the Action Center on the project dashboard?

If you have multiple implementation projects, the Configure button might not be available, and a warning message in the Action center might indicate that the number of licenses is insufficient. The Edit estimate button in the Subscription estimator tool lets you edit an active subscription estimate and apply the desired license allocation for that project.

Why does an error occur when I mark an estimate as Active?

When you mark an estimate as Active , you might receive the following error message:

Estimate created but does not meet requirements

This error occurs if transaction lines that are entered aren't within the limits of the Subscription estimation tool. To resolve this error, create a support request, and attach the usage profile. Your instance can then be manually sized.

How can I update my subscription if my production environment is deployed?

The Subscription estimator is a required step before you request production. Although you can have multiple estimates, one estimate must be marked as Active . The active subscription estimate is used to size the production environment. After the production environment has been deployed, or after deployment of the environment has received sign-off, the active estimate is locked. To edit an active subscription estimate, select the Edit estimate button in the Subscription estimator tool to update your license allocation.

What should I do to activate my subscription estimate if I have multiple projects in the same tenant?

When you're implementing several projects in the same tenant, a warning message in the Action center in LCS might state, "subscription estimate is not complete." This warning will indicate that the total number of estimated users for all implementation projects should not exceed the number of purchased licenses. This situation can occur if the total users in the active subscription estimates exceed the tenant license count of the same type. To edit the active subscription estimate, select the Edit estimate button in the Subscription estimator tool to update your license allocation.

FastTrack solutions architects aren't involved in uploading or updating the Subscription estimator. If you identify any warnings about the Subscription estimator in LCS, follow the instructions in this article. If you continue to have issues, contact Microsoft Support.

If you receive any other error message or encounter other issues, create a support request, and attach your active estimate so that the Support team can address the issue.
