  A data architect has two tables that contain Sales and target data for employees. The tables are loaded into Qlik Sense and are associated by EmployeeID. The data architect creates a bar chart of total Sales vs. Target. The architect notices some values for target are too high, and employees with NO sales should be excluded.

  In the data load editor, the tables are loaded in the following sequence:

  1.

  OrderHeader

  2.

  OrderDetails

  3.

  Products

  The three tables CANNOT be modified as all fields are required. A data architect must create a Cost of Goods Sold (COGS) field calculated as UnitCost* Quantity. Some products may NOT have UniCost, so the COGS value must be zero for these products.

  How should the data architect meet this requirement?

  A. 1. Load the Products table as the first table

  2. Create a new field in the OrderDetails table: Quantity * IsNull (UnitCost) as COGS

  B. 1. Perform a preceding load on the Product table

  2. Create a new field in the OrderDetails table: if((UnitCost ?null() or ", 0) * Quantity as COGS

  C. 1. Join the Products and OrderDetails on ProductID

  2. Create a new field in the OrderDetails table: Replace(Null, 0, UnitCost) * Quantity as COGS

  D. 1. Create a mapping load table as the first table from the Product table

  2. Create a new field to the OrderDetails table: ApplyMap (`UnitCost_Map', ProductID, 0) * Quantity as COGS

  Correct Answer: D
