The order of operations in Tableau, sometimes called the query pipeline, is the order in which Tableau performs various actions. Actions are also known as operations. Many operations apply filters, which means that as you build a view and add filters, those filters always execute in the order established by the order of operations. Show

This article includes two scenarios for updating a view to correct problems resulting from the order of operations: converting a dimension filter to a context filter, and converting a table calculation to a FIXED level of detail expression. About the order of operations (aka query pipeline)Sometimes, you might expect Tableau to execute filters in one order, but the order of operations dictates that they be executed in a different order, which gives you unexpected results. When this happens, you can sometimes change the order in which operations are executed in the pipeline. The Tableau order of operations includes the following, from top to bottom.
Note: In the order of operations, the latest date filter is global to the workbook, while context filters apply per worksheet. The latest date is determined just after the workbook opens for first use, after data source filters, but before context filters. At that point the date is set, and the latest date preset is used as a dimension filter. Example 1: Convert a Dimension Filter to a Context FilterThis and the following example use the Sample – Superstore data source provided with Tableau Desktop. In this example, the view addresses the following question: Who are the top 10 customers, by total sales, in New York City? The view contains two dimension filters, one that you create on the General tab in the Filters dialog box, and the other on the Top N tab. The problem is that these filters are executing simultaneously, whereas you would like to general filter to be applied before the top n filter, so that the top n filter can act on the results as previously filtered by the general filter. The solution is to redefine one of the filters as a context filter so that a clear order of precedence is established. Here are the steps for building this view.
Example 2: Convert a Table Calculation to a FIXED Level of Detail ExpressionIn this example, the view addresses the following question: What is the percent of total sales by product sub-category? The view contains a dimension filter and a table calculation. Tableau applies the dimension filter before executing the table calculation. To invert the order of these operations, use a FIXED level of detail expression instead of a table calculation. Here are the steps for building this view.
Why is speed important in operations?Speed is important, but not at any cost. The costs of maintaining a large physical footprint, expediting, overtime and managing inventory can severely erode cost competitiveness and profitability.
What is transformation process model of operations management?3 The transformation model
Operations management involves the systematic direction and control of the processes that transform resources (inputs) into finished goods or services for customers or clients (outputs).
Why is operations also referred to as a process of transformation?Operations is often defined as a transformation process. Inputs such as raw materials, labor, equipment, and capital are transformed into outputs (goods and services).
What is a typical fill rate goal coursera?On average, companies have a fill rate in the range of 85-95%. Top-performing companies manage 98-99%. Of course, the more items and variants of those items that you offer, the harder it is to stock the right amounts of everything.
