Energy Pivot Values: Bidirectional Relationships during the Strength Pivot

Energy Pivot Values: Bidirectional Relationships during the Strength Pivot

Bidirectional relationships are served inside the Strength BI while the both BI designers need certainly to synchronise slicers having studies analysis

  • one-to-of numerous
  • one to-to-one to
  • of several-to-of numerous.

A relationship are establish just like the unidirectional (i.age. flowing in one single guidelines, the latest default conduct) or bidirectional (i.elizabeth. flowing both in guidelines). When you look at the a great unidirectional matchmaking the latest filter context was propagated on the one-top into of a lot-top, but not the other way around. Given that first step toward Fuel Rotate, the main one-to-of several relationships was a regular unidirectional relationship. On example over, the consumer desk is found on the fresh step one region of the relationship and Transformation desk is on the many side of the matchmaking (i.e. i e customer). In cases like this, we explore a familiar community ‘Customers Key’ to participate both tables. ‘Consumer Key’ here’s utilized just like the unique code that helps to help you identify for every customer title. Zero copies of the Customer Trick are permitted regarding the Customers desk. On the other hand, on Transformation desk, ‘Consumer Key’ may be used several times in the event the you can find numerous ideas off sales for specific users. This is the way you to definitely-to-of numerous matchmaking try defined anywhere between measurement tables (browse dining tables aren’t to the one to (1) side of the relationship) and you will facts dining tables (referred to as factual study dining tables on the many edge of the connection). The whole Stamina Pivot Vertipaq motor was optimised to utilize it (one to of numerous) kind of relationships.

We establish the connection between your Sales table together with Diary table, based upon this new attribute Day. But not, it must be pointed out that from inside the Fuel Pivot, only one-to-of many relationship are available, no bidirectional filter out is actually greeting throughout the editor. Luckily for us, the brand new DAX system inside Excel 2016 encourages DAX rules to get to the outcome of good bidirectional filter out. The new DAX mode CROSSFILTER adds a 3rd argument that provides the latest ability to customize the assistance of propagation of filter out for the a relationship. Available objections tend to be Nothing, OneWay and Each other. We’re going to look at this means after.

Why don’t we examine the situation within the Stamina BI. Let’s take a look at a straightforward example. I have five (4) tables and you may relationships options just like the revealed less than (quantity implies the fields connect):

The sales table was filtered of the Buyers table into the ‘Customers Key’ therefore the Device dining table is filtered towards the ‘Product Key’ which have a great unidirectional you to-to-of numerous relationship. We produce the article on conversion process dependent the information and knowledge and you may dating over. In this instance, the result could be:

So it habits really works okay in the most common circumstances. It is very preferred in order to filter sales depending customers or products’ services. When we want to make use of several slicers (you to definitely on consumer identity and another into the tool identity) in order to filter the sales, the end result table was:

Discover about three different it is possible to real dating sizes in databases framework not every served https://datingranking.net/es/citas-en-tus-40/ when you look at the Fuel Rotate

The latest report work once we expected. It strain product sales because of the customers A great. not, the ‘Device Name’ slicer doesn’t work. Such, customer An excellent simply is the reason this new purchases off unit Cherry and you can Dragon fruits, but tool Fruit and you may Banana remain on this new slicer record. Ergo, the newest slicer ‘Tool Name’ does not promote simple viewpoints with the customers. The reason is simple: brand new filter on Buyers is at Conversion process, which simply filters the sales of your chosen consumer. However, the newest filter out doesn’t immediately is born the sales table to help you the product dining table of the unidirectional relationships. If we should filter Product dependent Customers, we are able to change the relationships anywhere between Product and you can Transformation so you can a good bidirectional relationships:
