I'm attempting to create multiple joins with two tables (Table A + Table B) using the same key from Table A. The key on table A is "Name" and there are multiple columns in Table B that I need to join this with. Any ideas on the best way to do this?
Just go ahead and do it. Power BI allows multiple relations between tables, but only one of them will be "active":
Multiple Relationships Between Tables
To use inactive relations, you will have to refer to them in DAX using function called
USERELATIONSHIP
Alternatively, you can replicate your table A as many times as you need, and setup regular relations. In my opinion, it's a better data model - it's more intuitive and easier to use.

I need help on this issue as i don't have any experience in Power Bi. I want to join 2 table in Power Bi where it have the same column which is Part_Number. How can i make this 2 table to match by Part Number and return the value?
Recon Table
Inventory Table
I would like to have Part Number, Part Name, QTY, Total Quantity as the result. Hope that i can the clarification i need. Thanks a lot!
For this case you simply must merge the tables. It doesn't look like you have done a lot of research on the matter though, so it's hard to understand exactly what you need help with.
To merge your two tables in Power Query, I would right click in the left hand side menu and select Merge Queries as New.
After that you simply follow the on-screen instructions and select your two tables and their respective key columns. After merging you can choose to disable load of your two original tables to save space in your data model, but this depends on your requirements.
If this was my data model, I would think on why joining these tables are necessary, instead of using these two tables as fact tables, and creating a third table to handle the part number dimension with associated part metadata.
Read the docs: Merge queries in Power Query
I am trying to create a table that is a list of all possible combinations between two tables: products and companies. I'm building a dashboard in Power BI and the data comes from SQL queries. I have the following list structures for the Products table and the Companies table:
and my desired output for analysis is:
There is nothing that relates the companies to the products, and I'm trying to get a list of all of the products for each company. Can I do this in Power BI? If not, is it possible in SQL (there is nothing to join on)? Thank you for your help!
You can do this with a 'hacked' join, or a cross join. I prefer the former from a process POV, but cannot speak to speed or efficiency.
Using a Join ( Merge in PQ )
Create a new column 'DummyKey' with a value of 1 on each table.
Merge both tables using your 'DummyKey' columns.
Complete the Join process and choose the columns you want to bring through.
Cross Joins in PowerQuery according to MS
I think this 'cross join' is only technically right and does not provide future flexibility.
Both methods will get you to the same end point, and can be done in SQL or PQ.
In my table primary key column have missing value, i have tried to fill using measure but it is not work because not full fill the primary key val of column to measure
For handling missing values, you need to follow the following two steps:
Replace the missing values with the desired values in Query Editor in Power BI Desktop (optional)
Remove the bi-directional relationships and create uni-directional relationships among tables
Note: The direction of the relationship plays a very important role in modeling in Power BI. The direction of the relationship means the way that filter propagates in Power BI. The uni-directional relationship will filter one table based on the other one. Sometimes you need to filter in a different direction, that is when the bi-directional relationship comes into play. However, bidirectional relationship comes with a cost of performance issues. Do not use bi-directional relationships blindly. Make sure you have designed your model in the right way first, and if that doesn’t work, then try other methods such as Cross-Filter DAX functions.
I have created static table as blow and create relationship with original tables then assigned value static table column on visual table which is working with out any issue
Create Static stable:
create relationship
assign column to visual table and filter result column should not be empty
I want to move(denormalize)two tables into another tabe,how can I do it?

I want to move these two tables into another table which is 'products'.
i tried Related function with calucated column and it won't work bcoz those tables sharing one-one relationship
plz solve my issue who are familiar with data modelling and dax in power bi
The best way is to use the merge function in power query, follow the tutorial on the below link it'll explain it better, this will allow you to join the tables you need into query, in turn creating a table in Power BI

In Power BI, I am creating a report with some finance data of a company. I have 3 different tables. The table structure of all three tables are as follows:
I want to change these tables into this structure:
Is it possible to achieve this kind of structure? If yes and please suggest some method to do this?
To do it simply you can import 3 times your table using the query editor, and then in one table keep only columns for Planned, in the second table keep columns for Actual, and so on...
Hope that helps!
