Returns BLANK() Cells on “Div by Zero”, No IF() or IFERROR() required! Overly-long and/or cryptically-named tables and columns make your formulas. For a Power Pivot / Data Model, you can only use one column in a relationship. You can concatenate columns in a new calculated column using the & operator. I need some help to understand how to use calculate with two different tables. linked to the CustomerData through the Country name, so the relations are as below: figure out a solution so I can create two or more Calculated Columns. . I found some info on compatibility issues between PowerPivot for.
Microsoft had to make compromises in the design to make this process fast, and one compromise is that there can only be 1 active relationship between 2 tables. In addition, the relationship MUST be one to many — no exceptions although this is changing in Excel edit: You can read more about 1 to many relationships and data shape in this article from my knowledge base. Why would you need Multiple Relationships at All? The most common scenario I have come across is when you have two date columns in your data table eg Order Date and Ship Date and you want to join both of these columns to the Calendar table.
If there were only 1 date column, then you would typically set up your data like this shown below. When you do this, you will get the following behavior as shown below.
Does value exist in another table
Note there are now 2 relationships, but one of them the second one added is a dashed line. If you hover the mouse over this new relationship with the dashed line and then right click, you will see a menu pop up as shown below. This is really the only information you will see in Power Pivot that refers to active and inactive relationships.
If you change the inactive relationship and make it active, then the active relationship will automatically switch to inactive.
How to Use Inactive Relationships For this blog post, I will keep the relationship between Sales[Order Date] and Calendar[Date] as the active relationship and leave the other relationship as inactive. The formula [Count of Orders] is simply as follows So now the problem is, how to count the orders that shipped on each day? DAX allows you to override the active relationship and use the inactive relationship in your formulas instead. The relationship MUST exist in the data model and be set as inactive for the above to work.

The Pivot Table now will look like this, showing for each date, how many orders were taken and how many orders were shipped. This would mean that you have 2 calendar tables and can use the one you need for the problem at hand. Which approach you use is really down to personal preference and also how you are planning to report on your data.
Great, so far so good. We write a simple measure… Total Sales: But then, disaster strikes.
Can´t create a relationship between two columns because one of the columns must have unique value
You like that idea well enough, but the boss decides that some products fit across multiple categories. A slingshot is both a Toy and a Weapon. So, you end up with a table like at leftwhere the same item may show many times, and the same category may show many times. One product may be in Many categories. One category may have Many products. There is a Many to Many relationship between categories and products.
Notice, that this was really a business requirement. Having a Products table and Sales table feels super natural. That table would work totally normal.
It would filter the ProductCategoryMap, like any other Lookup table filters the fact tables hanging off it.

Uh… does it like … do anything? However you like to think about that.
It used to look totally magic to me, but I am starting to get used to it. But, it does suit our needs quite nicely. If we put ProductCategoryMap[Category] on rows of a pivot… then our new [Total Sales M2M] measure will be evaluated for each row… and once that Category filter gets applied, we are left with just the Products in our bridge table that map to the Category on rows.
Yes, I realize you need to go re-read that sentence.
