Bidirectional cross-filtering in Power BI: what is it and how does it work? (2023)

OCROSS FILTERwayindicates the direction of cross-filtering to use in a calculation for athe ratio of two columns.

This function takes advantage of existing relationships in the model to determine the cross-filtering direction of the specified relationship, distinguishing relationships by their end columns. When necessary, this filter is applied using many-to-one relationships, which is an extremely efficient and logical technique.

What does Cross Filter Direction mean in Power BI?

Compared to other database management systems, Power BI relationships are a little different. Most systems have only one relationship and no specific direction for it. However, youThe Power BI relationship has a direction.Cross direction filter in Power BIhas a big impact on how filtering works.

What is two-way cross-filtering in Power BI?

Report writers and data modelers now have more control over how filters are applied when processing related tables, thanks to bidirectional cross-filtering. They can apply filters to both sides of a table relationship using bidirectional cross-filtering. By propagating the filter context to another related table on the other side of a table relationship, developers can apply the filters.

Advantages of bidirectional cross-filtering

The two-way cross-filtering tool in Power BI is popular with creators. It certainly comes with a host of benefits.

  • You get calculations fromboth sides of a matrix relationshipwhen you apply filters on both sides. This obviously means you get more responses, which means you don't miss out on critical information that can lead to important business decisions. Left-to-right connections are not always enough to satisfy a modeler's needs. Sometimes it is necessary to examine how a relationship works in the opposite direction. You can meet more of your data needs with bidirectional cross-filtering.
  • You can create and deliver more detailed reports as a result of the additional information gained from bidirectional cross-filtering. That way, you're not the only one who benefits from the extra knowledge. Your end users will also be able to avoid losing important information, resulting in superior overall information. Ultimately, more detailed data can help you make better overall decisions for specific departments or the entire company.
  • You also don't have to do the math yourself, because bidirectional cross-filtering is already built into the Power BI solution. You also don't need to hirecomplex DAX formulas, which are useful but time consuming under these conditions. You can simply apply the relevant filters right away.

Finallythe benefits of bidirectional cross-filteringthey are as diverse as the modelers who use them. The more familiar you become with your options, the more confident you will be in applying them to your reports.

Two-way cross-filtering challenges

The most difficult challenge with bidirectional cross-filtering is how it affects the overall performance of Power BI. The option puts the application under a little more pressure than unidirectional filtering. As a result, excessive bidirectional cross-filtering can cause Power BI to slow down.

Users can use this as needed, but should try to avoid making it the default. In this way, the performance would be much more efficient and hassle free.

the belongingsfiltering options in Power BIthey must be balanced. All the options a user needs are there, but the default settings ensure that Power BI works well.

How to change default visual settings in Power BI?

Step 1: Select a view to activate it.

Step 2: Show visual interaction options.

Select the dropdown menu on the report's menu bar in the Power BI service.

To chooseFormat > Interactionsfrom the desktop menu.

Then select edit interactions. All other visualizations on the report page get highlighted and cross-filtered Power BI icons.

Punch filters and other views are now selectable. When drilling down or scrolling in a visualization (Drill Down and Up), changes will now match the current drill selection.

Modo CROSS FILTER no Power BI –

Example: Suppose you have a report that shows what products a company sells and where they were sold. For every sale, they have the mall where it happened. Of course, a single product could have been sold in several different centers. For each product, they want to know how many centers it is sold in:

Using cross filtering –

Trinity:Set it upCross filter direction on both, will allow Purchasetable to filter Centretable. This should make the center count correct for each product.

Trin para:Create two sculptors, one with the product names and one with the center names.

What happens when you try to filter the table using the Product Nameslicer?

Some of the center names disappear.

Using a DAX measure to temporarily change cross-filtering

In the relationship view, change the filtering to single –

  1. Filtering by center must change the products you see, but changing the products must not affect the centers shown: that is, the relationship must be unidirectional. This can be done by creating a target that mimics the effects of this change:
  2. you can use thisCALCULATE wayto change the filter environment of a calculation (such as the relationship between two tables).
  3. CROSSFILTER takes columns from each table used to join the tables and allows users to specify the allowed filtering direction.
  4. The measure will show the number of stores for each product as if both relationships exist, while the count shows that the relationship does not. All center names will now be displayed.

Check out cross filtering charts in Power BI

First, create a Power BI report with at least two chart objects. Then perform the following steps:

  1. Select the new Edit button in "visual interactions"no suspense menu.
  2. Select one of the charts.
  3. A set of three icons appears next to all other graphics on the page.
  4. If you select the pie chart icon, the original chart will be visually filtered using shading to show the new ratio - this was the default behavior.
  5. When you click the filter button, the entire chart is updated for the selected subset of data.

The graphic will not be filtered if you select the Ghostbusters emblem. After selecting the desired behavior, click the Edit button again and the icons will disappear.

Each individual graph on your canvas can have its cross-filter behavior customized exactly how you want it to cross-filter other graphs - complete granular control.

Optimizing cross-filtering performance using clustering expertise

Filtering options for one-way filtering work on the table where we collect values. There can be more than one way to send fields in tables with bidirectional filtering. When you create visualizations that use fields from different tables, this ambiguity can confuse Power BI and cause problems.

However, with astar shaped modellike this,bidirectional filteringit is absolutely safe for our relationship. Determining the appropriate table mappings can affect how your data model works. Global awareness allows data teams to limit the amount of data requested, avoiding the risks of data mining, which can be quite inconvenient for analytics teams.

Cross filtering in Power BI: recommended or not?

There is always a performance hit when performing cross-filtering; therefore, users should only do this when absolutely necessary. Cross-filtering is believed to be one of the main performance killers for Power BI as Power BI really needs to do a lot of work with it.

Finally, the cross filter is a useful feature for changing the direction of a relationship. Instead of changing the direction of the relationship, this method can be used. But before you start, thinkbest practices for power bi-cross filter modeling.

Common questions -

1.How do visuals filter in a Power BI report?

– Selecting a data point on a graph on a report page will automatically cross or highlight the other graph on the page. The report designer determines how charts on a page interact. Designers can turn visual interactions on and off, as well as customize the default behavior for cross-filtering and drilling.

2.How do you connect two filters to Power bi?

– To connect to the data source and import it into your model, use Excel or Power BI Desktop. You can create a calculated or measured column as part of the data model in Excel or Power BI Desktop, or you can create a calculated or measured column as part of the query using the "M" code.

CALCULATE is defined asCALCULATE(,,...). This means you can apply multiple filters at the same time. Multiple filters, on the other hand, will work together. In other words, the data must meet both requirements.


Bidirectional cross-filtering in Power BI: what is it and how does it work? ›

Bidirectional cross-filtering enables them to apply filters on both sides of a table relationship. You can apply the filters by propagating the filter context to a second related table on the other side of a table relationship.

What does cross filter direction mean in Power BI? ›

Single cross filter direction means "single direction", and Both means "both directions". A relationship that filters in both directions is commonly described as bi-directional. For one-to-many relationships, the cross filter direction is always from the "one" side, and optionally from the "many" side (bi-directional).

Why should we avoid bidirectional relationships? ›

The reason that overusing bidirectional relationships increases the model ambiguity lies in filter propagation. In Chapter 8, Data Modeling Components, we covered the concept of filter propagation as well as bidirectional relationships.

What is the use of cross filter and cross highlight in Power BI? ›

Cross-highlighting doesn't remove the unrelated data from those visuals. The unrelated data is still visible but dimmed. Cross-filtering Selecting a value in one visual acts more like a filter in other visuals, such as line charts, scatter charts, and maps. In those visuals, only the related data remains visible.

What is cross-filtering? ›

Cross-filtering makes it easier and more intuitive for viewers of dashboards to interact with a dashboard's data and understand how one metric affects another. With cross-filtering, users can click a data point in one dashboard tile to have all dashboard tiles automatically filter on that value.

What is the advantage of bidirectional? ›

One of the main advantages of bidirectional searches is the speed at which we get the desired results. It drastically reduces the time taken by the search by having simultaneous searches. It also saves resources for users as it requires less memory capacity to store all the searches.

How does bidirectional work? ›

With a bidirectional charger, the converter can transform the car's DC energy back into AC electricity and pass it along to another recipient. Efficiently running this bidirectional conversion process requires smart-charging technology, which manages how and when the car takes or returns energy.

What are examples of bidirectional relationships? ›

Bidirectional Relationships

If an entity has a related field, the entity is said to “know” about its related object. For example, if Order knows what LineItem instances it has and if LineItem knows what Order it belongs to, they have a bidirectional relationship.

Is cross filter direction single or both? ›

Both - This is the most common, default direction. This means for filtering purposes, both tables are treated as if they're a single table. This works well with a single table that has a number of lookup tables that surround it.

What are the 3 types of filtering processes? ›

Filters may be classed according to the nature of the driving force that causes filtration (i.e., gravity filters, pressure filters, and vacuum filters).

What are the 4 types of filtering? ›

Filters can be active or passive, and the four main types of filters are low-pass, high-pass, band-pass, and notch/band-reject (though there are also all-pass filters).

What are the five types of filtering? ›

The 5 Types of Filters

What is crossfilter dimension? ›

Crossfilter is a multi-dimensional dataset. It supports extremely fast interaction with datasets containing a million or more records.

How does filter function work? ›

The FILTER function allows you to filter a range of data based on criteria you define. In the following example we used the formula =FILTER(A5:D20,C5:C20=H2,"") to return all records for Apple, as selected in cell H2, and if there are no apples, return an empty string ("").

What is a filter and how do you use it? ›

Filters are systems or elements used to remove substances such as dust or dirt, or electronic signals, etc., as they pass through filtering media or devices. Filters are available for filtering air or gases, fluids, as well as electrical and optical phenomena. Air filters are used for cleaning the air.

Why is database called bidirectional? ›

This type of data is called "bidirectional" because it changes direction in the middle of a line.

Is bidirectional optimal? ›

The path from the initial state is then concatenated with the inverse of the path from the goal state to form the complete solution path. Bidirectional search still guarantees optimal solutions.

What is difference between sum and SUMX? ›

SUMX is an iterator function and takes a different approach. Unlike SUM, SUMX is capable of performing row-by-row calculations and iterates through every row of a specified table to complete the calculation. SUMX then adds all the row-wise results of the iterations of the given expression.
