Purchase spend analysis Power BI content

This article describes what is included in the Purchase spend analysis Microsoft Power BI content. It explains how to access the Power BI reports, and provides information about the data model and entities that are used to build the content.

Overview

The Purchase spend analysis Power BI content was designed to help purchasing managers and managers who are responsible for budgets keep track of purchase spending. Managers can analyze purchase spending in the following ways:

• Year-to-date purchase (by vendor group and individual vendors, procurement category and individual products, and vendor location)
• Year-over-year purchase change (by vendor group and procurement category)

The content uses purchase transactional data, and provides both an aggregate view of the company-wide purchase figures and a breakdown of purchase spending by vendor and product. Reports highlight changes in purchase spending over time. Therefore, the reports can be used to alert managers about positive and negative spending trends for individual vendors and products. Additionally, charts show purchase spending for different procurement categories and vendor groups. Therefore, category and regional managers can use the charts to help identify changes in spending behavior.

Accessing the Power BI content

The Purchase spend analysis Power BI content is shown on the Purchase and spend analysis page (Procurement and sourcing > Inquiries and reports > Purchase performance analysis > Purchase and spend analysis).

Data model and entities

The following data is used to fill the report pages in the Purchase spend analysis Power BI content. This data is represented as aggregate measurements that are staged in the Entity store. The Entity store is a Microsoft SQL Server database that is optimized for analytics. For more information, see Power BI integration with Entity store.

The aggregate measurements in this content are the subset of aggregate measurements that were available in the Purchase Cube in Microsoft Dynamics AX 2012 and Microsoft Dynamics AX 2012 R3. To stage the cube's aggregate measurements in the Entity store, you must make them deployable. For more information, see the procedure for staging aggregate measurements in the Entity store in Power BI integration with Entity store. The following key aggregate measurements are available directly from the Invoice lines entity and are used as the basis of the content.

Entity	Key aggregate measurements	Data source	Field	Description
Invoice lines	Purchase	VendInvoiceTrans	SUM(LineAmountMST)	The amount in the accounting currency.

The following table shows the key measurements in the content that are calculated from the Invoice lines entity.

Measure	Calculation
Purchase current year	Purchase current year = SUM('Invoice lines'[Purchase])
Purchase last year	Purchase last year = CALCULATE(SUM('Invoice lines'[Purchase]), SAMEPERIODLASTYEAR(Dates[Date]))
YOY purchase growth	YOY purchase growth = [Purchase current year] – [Purchase last year]

The following key dimensions in the content are used as filters to slice the aggregate measurements, so that you can achieve more granularity and gain deeper analytical insights.

Entity	Examples of attributes
Vendors	Vendor groups, Vendor country or regions, Vendor name
Products	Product number, Product name, Item groups name
Procurement categories	Procurement category, Procurement category names
Legal entities	Legal entity name
Dates	Dates, Year offset

By default, the content shows data for the current calendar year. However, you can change the date filter in the report filters section. You can also change the company filter.
