Goal
Create a data entity that will contain all sales headers and sales lines. This data entity will be used in Power BI and other third party applications. For every sales line in the header, the header record will be repeated.
Attempt
I tried creating a data entity with the SalesLine table and joining the SalesTable table on the SalesId. When I try to browse my staging table, I have no data at all. Is there something I am missing with the SalesTable tables and their relations?
