问题 I want to scrap data from this page (and pages similar to it): https://cereals.ahdb.org.uk/market-data-centre/historical-data/feed-ingredients.aspx This page uses Power BI. Unfortunately, finding a way to scrap Power BI is hard, because everyone wants to scrap using/into Power BI, not from it. The closest answer was this question. Yet unrelated. Firstly, I used Apache tika, and soon I realized the table data is been loading after loading the page. I need the rendered version of the page.

问题 I'm trying to build a simple report in Power BI based upon data published on a website. Here is what I want to achieve This website publishes data for COVID cases in the country.

问题 I am working on a multi-tab dashboard for commercial stores related variables with a star schema. I have many tabs which all feed from different tables and are all linked through a table ("Slicer_table") that feeds the slicer in every tab and is related to each table through a key of a concatenation of descriptive variables of the stores. In one of those tabs, I calculate a rate between some event and the total number of clients. For this calculus, I use 2 tables, one which feeds all the

问题 I am new to power bi. I have power bi account there I created some dashboards with some reports, now I want to consume those dashboard and report using power bi rest API (https://docs.microsoft.com/en-us/rest/api/power-bi/)in our own application. Our application we used the .net core for back-end and angular 6 for the front end. We need to call power bi API from the .net core.

问题 I'm trying to create a matrix in a Power BI report summarizing Salesperson performance sliced in a number of different ways. I know how to create a matrix with Rows - Salesperson, Columns - Product Type, and Values - count of Sales which will show the number of Sales per Salesperson per Product Type, but I'd like also be able to do the following: Add an additional column set to pivot on (e.g. Sales Year), so that I could see count of Sales pivoted by both Product Type and Year in the same

问题 We have a task to be able to connect to HFM in Power BI. I found this article: https://poweronbi.com/2016/04/from-hyperion-planning-or-hyperion-financial-management-to-power-bi/ but i dont understand HOW the database tables were/can be loaded from HFM into PowerBI. This is as far as the statement goes, without any demo or explanation in step1-2: I have attached a screenshot of the HFM data base, and you can load all the tables listed in the left column and load it to Power BI with Power Query

问题 Should we construct bridge tables with DAX or M? Picture stolen from here It seems very tempting to use DAX. With DAX the code is short and clear: IDList = DISTINCT( UNION( DISTINCT(Table1[ID]) ,DISTINCT(Table2[ID]) )) Moreover, DAX tables do not need to be loaded as M tables. However I wonder if advantage of DAX over M is not illusory? M seems to load once and DAX seems to be calculated on the fly, maybe anytime, over and over? 回答1: DAX calculated tables are re-calculated if any of the

问题 I have an ID column and I am looking for ways to increment my IDs each time a specific item appears in my Geography column ( ItalyZ , ItalyM , UKY or UKM ) is found. The ID of ItalyZ starts at 0 and ends at 4000. The ID of ItalyB starts at 4000 and ends at 8000. The ID of UKY starts at 0 and ends at 4000. The ID of UKM starts at 4000 and ends at 8000. However, I am refreshing my file, and I will thus have from time to time new arrivals of "geographies" without the origins or first IDs. These
