How to get started with RSO (Resource scheduling optimization) purchase in Dynamics 365 Field Service.
Even if you have a partner subscription or a free trial of field service, you will not be able to buy add on RSO and you will need to either request a trial from Microsoft representative or buy full Field Service license (or PS etc.) and then add Add On (Unfortunately)
First thing needs to do is login to your Microsoft 365 account and go to admin centre>Purchase services
Once in purchase services, go to Dynamics 365 and select Dynamics 365 Field Service, add to basket.
Next, go to Add-ons and look for Dynamics 365 Field Service – Resource Scheduling and you should be able to see option as below.
Once you have added Field Service to basket, got to Cart and look for Dynamics 365 Field Service Resource Scheduling Optimization and select Buy Now.
Next on check out page you will be able to see total amount.
You can either select monthly subscription and cancel on one month notice or can go annually.
Once you have made purchase, go to following URL to manage and configure RSO (assuming you have already installed Field Service solution)
and then Select Environment > Manage Solutions
Whole process takes some time and you can carry on working and this will be running in the background.
