# Power Pivot Principles: Conditional Custom Columns Using IF, OR and ‘||’

9 April 2019

Welcome back to our Power Pivot blog. Today, we discuss how to create conditional custom columns with multiple criteria… again.

Today we discuss the different methods to create conditional custom columns in Power Pivot, this time using the OR function and the ‘||’ operator.

Let’s have a look at the following data set…again:

We have a Table with three categories and a column with customer names.  We are going to assume that this Table has been retrieved by Power Query (otherwise known as Get & Transform) and loaded into our data model in Power Pivot.

For the purposes of this exercise, let’s assume that we wish to create a conditional column that will return with the value “Included” if a customer is “Y” in Category 1 or “N” in Category 2.

We would use the following code to create our custom column:

=IF(OR([Category 1]="Y", [Category 2]="N"),"Included",BLANK())

As we can see our logic works and we get the desired result:

What if we want a conditional column with three conditions?

• Category 1 = “N”
• Category 2 = “Y”
• Category 3 > 1

Keeping in mind that the OR function in Power Pivot only allows for two logical statements:

OR(Logical 1, Logical 2)

We will have to use a dreaded nested IF formula:

=IF(OR([Category 1]="N",OR([Category 2]="Y",[Category 3]>1)),"Included",BLANK())

We achieve the intended result:

That’s all well and good, but what if we have four or five criteria?  We do have an alternative we can use the ‘||’ operator.

The ‘||’ operator serves as a substitute to the OR function so we can write the following formula:

=IF([Category 1]="N" || [Category 2]="Y" || [Category 3]>1,"Included",BLANK())

The ‘||’ operator allows us to combine several criteria into one logical test for the IF formula drastically simplifying the formula.  That being said, the ‘||’ operator is a great way to avoid creating nasty nested IF formulae when creating our custom columns in Power Pivot.

That’s it for this week, tune in next week for more Power Pivot, until then happy pivoting!
