I am new to PowerBi and I am trying to work on some tables (in this example I am working with data on the corona virus).
I built a new table and named it "table1". Now I want to reach out to this table but Power BI cannot find the related table. You can see in the screenshot, how PowerBi is not considering the table.
the two tables are connected by a 1_to_many relation (table1 has every country once; the current table has every country often).
Thanks in advance for your help!
Best regards

Hello I am working on a dashboard that needs to combine 2 tables: sales table, sales order table. Two two tables come from different sources: sales table from SAP BW and sales order table through a dataflow. Both tables have a number of applied steps that delete, reformat and rename the columns. I then want to append the Sales Order Table to the Sales table. In the desktop version everything works even if I hit "refresh all" in the Power Query Editor. When I publish the report to the service and refresh, I am getting an error saying: The key didn't match any rows in the table
Full Error Message:
After troubleshooting for the last couple of days I'm pretty sure that the issue has to do with my column names being renamed. However its strange that the append would work in desktop but not in service.
My main questions are:
Can you append tables after multiple applied transformation steps?
Can the tables both refresh daily or does one or the other have to be static?
Does the order of the table queries in query editor effect the order in which tables are loaded or does everything load all at once? Can this order affect my append query?
Any suggestions or help would be greatly appreciated. I am 99% of the way to launching this new report but this refresh issue is driving me crazy.
You can append tables after multiple applied transformation steps
Both tables can refresh daily
The order of the table queries in query editor doesn't matter. Power BI will determine the order in which they are loaded. E.g. if you want to append a table to another table, that other table is loaded first.
Thanks for answering those questions Peter. I concluded that the issue had something to do with appending a dataflow. I switched to a new data source from SAP BW and its working now. What's interesting is that the dataflow is still being imported and refreshed daily so the issue had to do with just the append.
I have a sql database linked where I have the complete history of products and users. I want to the user to be able to select on the slicer a year and the data automatically shows active prodcuts, expired products and new products added in that year (or snapshot).
Is there a way this can be done? I am not able to find a measure to best do this for me.
I recommend creating a date dimension table first - I usually call mine Calendar. Please read this useful post by Radacad which will show you how to create one > https://radacad.com/power-bi-date-or-calendar-table-best-method-dax-or-power-query
Once it's done create relationships between your fact tables and calendar table on key dates of when your products are active or expired - I'm making a huge assumption that's what your tables store.
Your calendar table will then act as a single time/date point of truth and should be used to slice and dice your fact table.
Hope this helps!
I am new in power bi. I am creating a basic tabular report in power bi. But the catch is I have multiple dates columns in the dataset (For Eg. productvalidfrom,productvalidto,ordervalidfrom,ordervalidto). And I want to filter these columns with a single date selection.
If I select 2021-09-01 then condition for filter will be
2021-09-01>=productvalidfrom and 2021-09-01<productvalidto and 2021-09-01>=ordervalidfrom and 2021-09-01<ordervalidto
and need to all the columns from the dataset. No summarization.
Thanks in advance.
I have been able to implement this before. You will need to add a data table to your data sources. Then you will want to create relationships between the dates in your data and the date table. Only one of them will be active relationships, the rest will be inactive. Then, your slicer will use the date from your newly created date table.
This link should be able to guide you through the build.
I have created a dataset in Power BI web, and then imported it on Power BI desktop (using File -> Get data -> Power BI datasets).
I don't see a way of adding Calculated Columns. Does the dataset need some special configuration to enable this?
Based on my experience you won't be able to see the columns because it using direct query. you can still add some columns and measure but your'e basically flying blind. you can just select the table in the report(visual view) and add column however you'll have to play the guessing game. But if you know your dataset you should be fine.
However a Dataflow wouldn't give the issue you're having.
I am a beginer to Power BI
I have loaded an sql table to power BI dataset. The table keeps udating with new records frequently. How can I always pull the data of the latest five records into the dashboard. There as id no which keeps growing with the no of rows.
another question, how can I show the dashboard specific to the current working day only? There is date stamp in the sql data. How can i use it? With filter I am able to select a particular date but to set it to current day or last week etc.
Thanks in advance.
If your data doesn't contain any field which would tell you, what then latest rows are, the there's not much you can do here. Apparently you have some sort of timestamp there, so a query something like this could work as the datasource for your report:
SELECT TOP 5 field1, field2... FROM Table ORDER BY Timestamp DESC
To your second question, you can add a reletive date filter: https://learn.microsoft.com/en-us/power-bi/visuals/desktop-slicer-filter-date-range
