+# Editing a Power BI dataset through the XMLA endpoint
+
+Once a change is made to a Power BI semantic model through the XMLA endpoint, it's not possible to download the dataset as a .pbix file from the Power BI service. 
+
+However, with the Power BI Project file, it's possible to create a .pbix file from the remote model by following the three-step process, which is described as follows. 
+
+![XLMA to PBIX Overview](~/images/power-bi/create-pbix-from-xmla-overview.png)
+
+> [!NOTE]
+> The described workaround isn't officially supported by Microsoft. There's no guarantee that it works for every model. Specifically, if you've added custom partitions or other objects [not listed here](https://learn.microsoft.com/en-us/power-bi/transform-model/desktop-external-tools#data-modeling-operations), Power BI Desktop may not be able to correctly open the file following this approach.
+
+## Step 1: Create and save an empty Power BI projects (.pbip) file
+
+The first step is to create a new Power BI report and save it as an empty Power BI Project (.pbip) file, as depicted in the following diagram.
+
+![Save PBIP file](~/images/power-bi/save-pbip-file.png)
+
+This creates a folder structure that contains an empty _model_ file. This _model_ file contains the model metadata. You'll overwrite this metadata in the next step with the metadata of the published model that you want to save to .pbix.
+
+![PBIP with Model file](~/images/power-bi/pbip-file-bim-model.png)
+
+Close Power BI desktop, and proceed with the next step in Tabular Editor.
+
+## Step 2: Open XMLA model with Tabular Editor and save the model as .pbip
+
+With Tabular Editor open, connect to the Fabric workspace via the XMLA endpoint. Load the Power BI semantic model you want to convert to a .pbix. 
+
+## Step 3: Save XMLA model into .pbip
+
+In Tabular Editor using _File > Save as..._, navigate to the Power BI Project folder. Overwrite the _model.bim_ file shown in the previous diagram. 
+
+This will save the remote model into the Power BI Project that will now contain the model metadata.
+
+
+## Step 4: Save to .pbix and open this file in Power BI Desktop
+
+![PBIP with Tables](~/images/power-bi/pbip-includes-tables.png)
+
+Open the .pbip and the Power BI report will now contain the XMLA endpoint semantic model.
+
+Save it to a .pbix using _File > Save As..._ in Power BI Desktop.
+
+## Re-hydrate .pbix
+The .pbix now contains the model that was published to the Fabric workspace. When you open the .pbix, you can _re-hydrate_ the file, meaning that you load the data based on the connections specified in the model.
