![Incremental Refresh Best Practice, Do NOT Publish Changes from Power BI Desktop](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_6f4f941a-1024x612.png?resize=900%2C538)
In a earlier put up, I shared a complete information on implementing Incremental Information Refresh in Energy BI Desktop. We lined important ideas comparable to truncation and cargo versus incremental load, understanding historic and incremental ranges, and the numerous advantages of adopting incremental refresh for giant tables. For those who missed that put up, I extremely suggest giving it a learn to get a strong basis on the subject.
Now, let’s dive into Half 2 of this collection the place we’ll discover ideas and methods for implementing Incremental Information Refresh in additional complicated situations. This weblog follows up on the insights offered within the first half, providing a deeper understanding of how Incremental Information Refresh works in Energy BI. Whether or not you’re a seasoned Energy BI consumer or simply getting began, this put up will present useful data on optimising your knowledge refresh methods. So, let’s start.
After we publish a Energy BI resolution from Energy BI Desktop to Material Service, we add the information mannequin, queries, stories, and the loaded knowledge into the information mannequin to the cloud. In essence, the Energy Question queries, the information mannequin and the loaded knowledge will flip to the Semantic Mannequin and the report will probably be a brand new report related to the semantic mannequin with Join Reside storage mode to the semantic mannequin. In case you are unsure what Join Reside means, then try this put up the place I clarify the variations between Join Reside and Direct Question storage modes.
The Publish course of in Energy BI Desktop makes absolute sense within the majority of Energy BI developments. Whereas Energy BI Desktop is the predominant growth instrument to implement Energy BI options, the publishing course of continues to be not fairly as much as the duty, particularly on extra complicated situations comparable to having Incremental Information Refresh configured on a number of tables. Right here is why.
As defined in this put up, publishing the answer into the service for the primary time doesn’t create the partitions required for the incremental refresh. The partitions will probably be created after the primary time we refresh the semantic mannequin from the Material Service. Think about the case the place we efficiently refreshed the semantic mannequin, however we have to modify the answer in Energy BI Desktop and republish the modifications to the service. That’s the place issues get extra complicated than anticipated. At any time when we republish the brand new model from Energy BI Desktop to Material Service, we get a warning that the semantic mannequin exists within the goal workspace and that we wish to Overwrite it with the brand new one. In different phrases, Energy BI Desktop at the moment doesn’t supply to use the semantic mannequin modifications with out overwriting the complete mannequin. Which means that if we transfer ahead, because the warning message suggests, we change the prevailing semantic mannequin and the created partitions with the brand new one with out any partitions. So the brand new semantic mannequin is now in its very first stage and the partitions of the desk(s) with incremental refresh are gone. In fact, the partitions will probably be created through the subsequent refresh, however this isn’t environment friendly and realistically completely unacceptable in manufacturing environments. That’s why we MUST NOT use Energy BI Desktop for republishing an already revealed semantic mannequin to keep away from overriding the already created tables’ partitions. Now that Energy BI Desktop doesn’t help extra superior publishing situations comparable to detecting the prevailing partitions created by the incremental refresh course of, let’s talk about our different choices.
Whereas we must always not publish the modifications from Energy BI Desktop to the Service, we are able to nonetheless use it as our growth instrument and publish the modifications utilizing third-party instruments, due to the Exterior Instruments help function. The next subsections clarify utilizing two instruments that I consider are the most effective.
Publishing (Deployment) Information Mannequin Adjustments with ALM Toolkit
The ALM Toolkit is a free neighborhood instrument constructed by the wonderful Christian Wade. After downloading and putting in ALM Toolkit, the instrument registers itself as an exterior instrument accessible inside the Energy BI Desktop. The next steps clarify publish the modifications.
The “ALM” a part of the instrument’s title refers to Software Lifecycle Administration. This instrument primarily focuses on easing the challenges related to managing Energy BI initiatives throughout totally different phases of their lifecycle. ALM Toolkit merely compares a supply knowledge mannequin with the chosen vacation spot. It’s able to detecting the created partitions on the Service and conserving them intact whereas making use of the modifications made within the Energy BI Desktop to the vacation spot Semantic Mannequin within the Service.
The left facet of the next picture exhibits a modified knowledge mannequin the place we added the Date desk and on the precise, we see the already revealed semantic mannequin in Material with out the Date desk.
![Modified data model in Power BI Desktop and its previously published copy on Fabric](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_5a4d79bb-1024x248.png?resize=900%2C218)
We now wish to evaluate the 2 in ALM Toolkit and apply the modifications to the semantic mannequin on Material. To take action, we have to copy the Workspace connection from the Workspace settings. The next steps clarify get the Workspace connection:
- After you log in to Material, navigate to the specified Premium Workspace
- Click on the Workspace settings
- Click on the Premium tab
- Scroll down to seek out the Workspace connection on the backside of the pane and replica the hyperlink
![Copy a Premium Workspace Connection on Fabric Service](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_5a4fed4b-1024x872.png?resize=900%2C766)
Preserve this hyperlink as we’ll use it within the subsequent part.
The next steps clarify use the ALM Toolkit to match the modifications made in an area mannequin from the Energy BI Desktop with the prevailing Semantic Mannequin within the Material Service:
- Choose the Exterior instruments tab
- Click on the ALM Toolkit to open the instrument which mechanically connects to the native Energy BI Desktop occasion because the Supply
- On the Goal part, paste the Workspace connection copied earlier on the Workspace textbox
- Move your credentials
- Click on the dropdown to pick the specified Dataset
- Click on OK
![Use ALM Toolkit to compare local Power BI Desktop data model with a premium semantic model on Fabric](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_5a5f5c38-1024x638.png?resize=900%2C561)
At this level, ALM Toolkit compares the 2 knowledge fashions and divulges the modifications. As the next picture exhibits, it detected the brand new Date desk and three new relationships added to the native mannequin that don’t exist on the goal. We are able to resolve which modifications we wish to apply to the goal by altering the worth of the Motion. We depart the default motion to Create.
![ALM Toolkit detected the differences between a local model on Power BI Desktop and the existing Semantic Model on Fabric](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_5a691c02-1024x629.png?resize=900%2C553)
Let’s proceed following the required steps as follows:
- Click on the Validate Choice button
- Evaluation the modifications and click on the OK button
![Validating the changes between the local data model in Power BI Desktop and the Semantic Model on Fabric with ALM Toolkit](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_5a6d4699-1024x782.png?resize=900%2C687)
- Click on the Replace button
- Click on Sure on the warning message
The ALM Toolkit now publishes the modifications and exhibits the progress on the Deployment window.
- Click on the Shut button

At this stage, all the chosen modifications have been revealed to the Semantic Mannequin on Material. ALM Toolkit provides us the choice to refresh the comparability afterward.
Word
This course of solely revealed the brand new modifications to the Service. These modifications embrace publishing the metadata, due to this fact, on the Semantic Mannequin on the Service the brand new Date desk and the three relationships have to be added, however at this stage, the Date desk continues to be empty. Therefore we have to refresh the Semantic Mannequin to seize the Date knowledge from the supply.
Publishing (Deployment) Information Mannequin Adjustments with Tabular Editor
Indubitably, Tabular Editor is without doubt one of the most helpful third-party instruments accessible to Energy BI builders created by the wonderful Daniel Otykier. This instrument is available in two totally different license classes, Tabular Editor v2.x and v3.x which have substantial variations. Tabular Editor v2.x is a free and open-source instrument that permits you to manipulate and handle measures, calculated columns, show folders, views, and translations in both SQL Server Evaluation Providers (SSAS) Tabular and Energy BI Sematic Fashions. Tabular Editor 3.x alternatively, is a industrial instrument that gives a premium expertise with many handy options to mix all of your knowledge modelling and growth wants in a single single instrument. Whereas Tabular Editor v2.x is freed from cost, it doesn’t have the superior options of Tabular Editor v3.x. Subsequently, the selection between the 2 variations will depend on the wants and preferences of the consumer. For the aim of this put up, we solely use Tabular Editor v2.x to publish the modifications made to our native knowledge mannequin in Energy BI Desktop to the Semantic Mannequin revealed to Material. You’ll want to obtain and set up the specified model of Tabular Editor which can register it as an Exterior Instrument within the Energy BI Desktop.
Think about we add a brand new Product desk to the information mannequin within the Energy BI Desktop.

At this level, the modifications are revealed to the Material Service. The next picture exhibits the Semantic Mannequin on the Service with the utilized modifications.
![The changes has been published from Power BI Desktop to the Fabric Service with Tabular Editor](https://i0.wp.com/biinsight.com/wp-content/uploads/2024/01/Snag_618e7c14-1024x649.png?resize=900%2C570)
As you see, whereas publishing the modifications from Energy BI Desktop to the Service utilizing Tabular Editor is a straightforward course of, we have to be cautious that, in contrast to ALM Toolkit, Tabular Editor publishes the present knowledge mannequin and all modifications to the Service. Which means that we wouldn’t have the choice to pick the modifications to be utilized to the Service.
Thus far we’ve realized two strategies to publish the modifications from Energy BI Desktop to the Semantic Mannequin on Material with out affecting the tables with incremental refresh. Nevertheless, these strategies solely work for situations that don’t require a full refresh of a desk with incremental refresh partitions.
A full refresh is required whatever the publishing technique, when there are modifications within the Energy BI Desktop that have an effect on the question or the partition settings, comparable to altering the filter vary, the incremental coverage, or the desk construction comparable to including new columns, eradicating columns, renaming columns, and so forth. A full refresh can also be required when there are structural modifications within the supply desk. Throughout a full refresh, the prevailing partitions will probably be eliminated, new partitions will probably be generated and reloaded from the information supply.
On this put up, we’ve realized take care of some intricacies of publishing Energy BI options with Incremental Information Refresh. We’ve realized to watch out once we publish modifications from Energy BI Desktop to the Material Service. In any other case, we lose the information partitions created earlier than which is fairly essential for manufacturing environments the place we have to maintain all the information intact in addition to safely deploy the modifications to the mannequin. To keep away from this drawback, we mentioned utilizing different instruments such because the ALM Toolkit and Tabular Editor. This fashion, we are able to maintain our knowledge partitions intact and replace solely what we’d like. We have now proven you use these instruments on this weblog collection.
I hope you discover this put up useful for enhancing your Energy BI publishing expertise. As all the time, please share your ideas with us within the feedback part under.
