The Power BI Gold for Purchasing dataset is organized in a star schema data model.
The Fact tables contain information about individual transactions from sources such as purchase orders, posted purchase invoices and posted credit memos. Dimension tables provide additional context and attributes to the transactional data, such as vendor and product information.
Fact tables store transactional data and support summarizations such as SUM, AVG, COUNT and more.
The Purchases table is a composite table made up of records from three sub tables;
- Purchase Value Entries
- Purchase Lines from received not invoiced purchase orders
- Purchase Lines where the outstanding quantity is greater than zero

|Document No.||The unique identifier assigned to the document or record associated with the transaction.|
|Document Type||The type of document or record associated with the transaction, such as Purchase Order or Invoice.|
|Entry No||For value entries this is the entry no. For all other records this is the purchase line number.|
