power bi create measure based on column value

[Year] & " - " & 'Table'[Date]. Using DAX measures to dynamically group data in Power BI is so powerful. You should already be familiar with using Get Data and Power Query Editor to import data, work with multiple related tables, and add fields to the report canvas. This article describes the possible rounding differences that can appear in DAX. SELECTEDVALUE does not support retrieving data from a column that is grouped by other columns because all the columns involved must be included in the same DAX grouping operation (such as SUMMARIZE or SUMMARIZECOLUMNS). This convention makes it easier to differentiate between measures and columns in code. In the Quick measures window, under Calculation, select Average per category. Returns a one column table that contains the distinct (unique) values in a column, for a column argument. To calculate "Sales %," enter the formula "Overall Sales / All-City Sales * 100". For example, for the SalesAmount field, Sum and Average are useful, and Minimum and Maximum have their place as well.

However, what happens if you want to show the gross margin as a percentage of the sales amount? For Eg., If period=Year then "need a measure value which holds running total Year wise" else if Period = Quarter then "need a measure value which holds running total Quarter wise" For example, a slicer with a filter on Sales[Quantity] would be ignored by the Big Sales Amount Overrides Filter measure. The matrix visual has a new column that shows the calculated Average Unit Price average per Category. You have to define a calculated column whenever you want to do the following: However, you must define a measure whenever you want to display resulting calculation values that reflect user selections and see them in the values area of a pivot table, or in the plot area of a chart for example: You can express some calculations both with calculated columns and with measures, even if you need to use different DAX expressions in these cases. Be sure to check out the DAX Resource Center Wiki, where influential members of the BI community share their knowledge of DAX. In Power BI Desktop, you have a different user interface. By combining data lakes, rivers, glaciers, and seas, it offers enhanced scalability, flexibility, and efficiency for todays data-driven organizations.

SELECTEDVALUE ( [, ] ). Measure 2 = CALCULATE(SUM(Financieel[Aantal]; FILTER(Financieel; Financieel[DimTransactionTypeID]=2))). The Fields Parameters feature in Power BI generates a slicer that cannot be read by using SELECTEDVALUE because internally the table uses the Group By Columns feature of the Tabular model (more details in the Grouping Columns section of the Tabular Presentation Layer in Mastering Tabular video course). However, Count doesn't make sense for the SalesAmount field, because while its values are numeric, theyre really currency. Nevertheless, when computing the aggregate value of a percentage, you cannot rely on calculated columns.
