What if you want to import a list of measures that do not already exist? This pattern does not rely on DAX built-in time intelligence functions. If you create the data model originally in Power Pivot, and you set the Mark as Date Table setting there, once you import the data model in Power BI, you can use all the time intelligence functions (including TOTALYTD and other scalar functions) even if the relationship does not use a column of Date data type. Another Column can be added to control the order in which the Calculation Items are displayed in the reporting interface. Microsoft Business Intelligence Developer with experience in developing Business Intelligence solutions. So far so good. Lets start off with a basic model without a Date-table. Syntax for Tabular Editor to create Time intelligence functions. In this video, youll learn how you can get all these cool tools on your Power BI desktop.

You can have many date tables in a single data model and this setting affects both the metadata read by the clients (which can provide a particular user interface to manipulate a date selection) and the behavior of certain DAX expressions that manipulates filters in a date table. Explainable AI Using Python Artificial Intelligence Model Explanations Using Python-based Libraries, . You can rearrange the order of your measures here. Initially, you will have one unique table created for the calculation group. You can use the data to see the periodic result in your report. If you need to automate this process, save the above script into a file and use the Tabular Editor CLI as follows: or, if you prefer to run the script against an already deployed database: Note: If you're using version 2.7.2 or newer, make sure to try the new "Import Table" feature. In this case "column.FormatString = "d/m/yyyy"" will not be enough to force a column to change its format. Evaluates the value of the expression for the dates in the quarter to date, in the current context. Section added on 2017-02-22 : you can create a calculated table (named MarkAsDateTable) using the following formula: Then, hide the MarkAsDateTable table and create a relationship between the Calendar table and the new MarkAsDateTable. Evaluates the expression at the last date of the year in the current context. A tag already exists with the provided branch name. In many if not all cases, these functions are .

Tabular Editor does unfortunately not have any mechanism for "parsing" such an expression, but if we wanted to replace the server and database names in this expression with something else, without knowing the original values, we can exploit the fact that the values are enclosed in double quotes: . Deep Explainer for Tabular Data . If you have a date column in the Calendar table that is not used as a key in the relationship with other tables, you can create a Date column in the other tables and then create a relationship using this column instead of the non-Date column. For example, if you marked a table named Calendar as a date table using the Date column (yes, too many Date names in practice, you have a column called Calendar[Date]), and you can write the following expression: The DAX engine automatically adds an ALL function over the Calendar table, removing any existing filter on other columns of the same table: However, this ALL statement is automatically applied when you apply a filter over a column of Date type that is the primary key in a relationship, regardless of the presence of the Mark as Date Table setting in the Calendar table. Then, go to "Project settings" > "Repositories", expand Branches, right-click on the develop branch and choose "Set as default branch". The script below will loop through all cultures in the model, and for every visible object, that doesn't already have a translation, it will assign the default values: Measures, columns, hierarchies and tables all expose the InPerspective property, which holds a True/False value for every perspective in the model, that indicates if the given object is a member of that perspective or not. It is still relevant if you use older versions of Power BI Desktop. You can see that the Total Cost depends on this table and this column. By default, only the following properties are exported (where applicable, depending on the type of object exported): To export different properties, supply a comma-separated list of property names to be exported as the 2nd argument to ExportProperties: The available property names can be found in the TOM API documentation. . But what if I wanted to see the same result for Total Cost? And then the last one is for Margin, which is basically the difference between Sales and Cost. particularly Time intelligence measures. Well, for a certain (small) subgroup of them now you can! In a Tabular model, tables and columns that are not hidden, will be visible to business users, and so it would often be preferable to use a "prettier" naming scheme. Particularly if you do time intelligence analysis (that is comparing values with the previous year, but many other things as well). Returns the first date of the year in the current context for the specified column of dates. Advanced SSAS Tabular management including object-level security, dynamic analytics, custom partitioning . You might get a warning message as Power BI does not yet support all the Tabular Editor features. For example, the script will convert the following: I highly recommend saving this script as a Custom Action that applies to all object types (except Relationships, KPIs, Table Permissions and Translations, as these do not have an editable "Name" property): Let's say you have a large, complex model, and you want to know which measures are potentially affected by changes to the underlying data. Developing ETL processes and data transformations (Azure Data Factory & T-SQL) Data warehousing (Kimball) Developing CI/CD pipelines for Azure Data Factory, SQL databases, Analysis Services and Power BI (in YAML) Report . For example, say have a base measure [Reseller Total Sales], and you want to make sure that all currently selected measures are visible in the same perspectives as this base measure. However I need the visual to show WoW and MoM, but you cant filter a single visual by both current week and current month, I can force the current Week to always be current week witohut any visual filter by using (I have a column in my date table working out the current dates), This again works fine and I can put both in one visual with no filter as you can see below.

Returns a table that contains a column of dates, shifted either forward or backward in time by the specified number of intervals from the dates in the current context. Evaluates the specified expression over the interval which begins on the first day of the year and ends with the last date in the specified date column after applying specified filters. First, create custom actions for individual Time Intelligence aggregations. In addition to getting/setting the membership in an individual perspective, the InPerspective property also supports the following methods: The latter may be used to copy perspective memberships from one object to another.
