Generating customer/item statistics report using financial dimension

Dear all,

trying to generate the customer/items statistics report in sales and marketing module of dynamics 365 FO using business unit financial dimension. In Ax 2012, i would have used table join to add customer transactions to customer invoice journal and then would have brought in the Dimension.BusinessUnit field to select desired dimension, in dynamics 365 FO after bringing in customer transactions, i am not seeing financial dimensions in available fields. how do i achieve this.
