### Calculus Function

The context of a calculation within a measure can be changed by using the calculus function. The ability to change the context is very important in the measure. The calculus function is very important in Power BI.

### The Total Revenues of the CSBO Project

The sum of Total Revenues will be shown regardless of the filters used. The table below shows the total revenue for all the data even when a conference field is shown.

### The ALL function and its variant are table objects

The ALL function and its variant are both functions that return table objects. If the REMOVEFILTERS function is supported by your tool, it's better to use it to remove filters.

### Calculate: A Function for BI

Power BI has a function called Calculate. When you begin using advanced formulas, you will often find that the calculus formulas are used to produce the desired outcome. You can easily compare year over year and month to date functions. Check out the videos to learn how to use time intelligence.

### Step 3: The scalar field in the standard model

Step 3 To check if the new Total Sales Red measure shows red sales only, drag Country, Total Sales Red and Total Sales on the canvas. The total sales red column shows the sales of products in each country.

### DAX: Dynamic Calculation Formulas

Dynamic calculation formulas where the results change depending on context are called measures. Measures are used to report that support combining and filtering model data by using multiple attributes such as a Power BI report or an excel pivot table. The model designer uses the DAX formula bar to create measures.

A formula in a measure can use standard aggregation functions, such as COUNT or SUM, or you can define your own formula by using the DAX formula bar. The named measures can be used to argue against other measures. The sum of sales amount is calculated and displayed for each product category when a user places the TotalSales measure in a report and then places the Product Category column from a Product table into Filters.

The measure's name precedes the formula in the measure's formulary. The name Total Sales appears before the formula. The name and definition of the measure are available to all users of the model after you've created it.

A table is a computed object, based on a formula expression, from all or part of other tables in the same model. A DAX formula defines the table's values instead of fetching and loading them from a data source. Tables that are calculated support relationships with other tables.

The columns in your table can be categorized into a data category. Any table can be named and surfaced. If any of the tables it pulls data from are refreshed or updated, the calculated tables are re-calculated.

### calcuLATE: A function for the evaluation of expressions modified by filters

The calcuLATE function allows you to evaluate an expression in a context that is modified by the specified filters. Wait, what? What does that mean?

### The DATE function and the date type

The DATE function takes the input datand converts it to numbers that are used to generate a date. The DATE function is useful in situations where the year, month, and day are supplied by formulas. The underlying data may have dates that are not recognized as a date.

The DATE function can be used with other functions to convert the dates to a number that can be recognized as a date. PowerPivot date functions always return a datetime data type, unlike Microsoft excel which stores dates as a serial number. If you want, you can use the formatting to display dates as serial numbers.

The day of the month is returned. The day function takes as an argument the day you are trying to find. Dates can be provided by using a function, an expression that returns a date, or typing a date in a time format.

You can use one of the accepted string formats for dates. The values returned by the year, month and day functions will be Gregorian values regardless of the display format for the supplied date value. If the display format is Hijri, the values for the year, month and day functions will be associated with the Gregorian date.

The indicated number of months before or after the start date is returned. EDATE can be used to calculate maturity dates that fall on the same day as the issue date. Microsoft excel stores dates as sequential serial numbers, but the DAX works with dates in a datetime format.

### Power BI Desktop and Hidden Measures

Jan is a sales person. Jan has been asked to provide sales projections for the next fiscal year. Jan bases the estimates on last year's sales amounts, with a six percent annual increase due to various promotions that are scheduled over the next six months.

Jan imports last year's sales data into Power BI Desktop to report the estimates. The SalesAmount field is in the Reseller Sales table. Jan renamed the SalesAmount field to Last Years Sales because the imported data only contains sales amounts for last year.

Jan drags the sales onto the report canvas. It is shown as a single value in a visualization of the total sales of all the reselling companies. Jan has a measure to calculate projected sales.

Jan can add other fields to the report to further analyze the projections. You can make a field appear in multiple folders by using a semicolon. The field appears in a Departments folder as well as a Names folder inside a Products folder.

Hidden measures are accessible in Power BI Desktop, however, you will not see them in Power BI services since they are considered client tools. Power BI Desktop has a breakdown of the basics of the DAX. The Data Analysis Expressions reference provides detailed articles on each of the functions, operators, and naming conventions.
