PowerBI Pro license question

Hi kiniadit，

From your description, I understand that you have two questions about Power BI license.

1.Actually, if your organization has purchased the Premium, you and your coworkers can view the report in the Premium capacity without Pro license. 

2. Currently, if you want to purchase  Power BI Pro for your organization ,you could subscription it through the Office 365 admin center. 

Normally, people who could have access to Admin portal under the Setting in Power BI Service should be an admin account and the person who purchased your Office 365 business subscription, he/she should be the global administrator.

I suggest you could consult your  IT department or have a contact to Office 365 support.

For further details about Power BI Pro license and Premiun , you could refer to this article.

Best Regards,

Cherry
