Hello,

I need help with a simple calculation. In my data source I have 2 date count columns, one is working days and one is calendar days. 

I then have a field with a customer. I want a new column that looks at the customer column, and then based on the customer either returns the date count value of working days or calendar days.

So, if 'Customer' = "A"

return value of working days count

if 'Customer' = "B"

return value of calendar days count

Working days count	Calendar days count	Customer
141	196	A
72	101	B
67	94	A
61	84	C
54	75	C
49	68	A

I just can't figure out how to do it.

Any help would be appreciated.

Regards,

Hello @EmilyM2019 

if you need a solution in Power Query, here is the solution

Create a new column and add this formula

if [Customer]="A" then [Working days count] else if [Customer]="B" then [Calendar days count] else "0"

here the complete solution

let
	Source = #table
	(
		{"Working days count","Calendar days count","Customer"},
		{
			{"141","196","A"},	{"72","101","B"},	{"67","94","A"},	{"61","84","C"},	{"54","75","C"},	{"49","68","A"}
		}
	),
    AddCustom = Table.AddColumn
	(
		Source, 
		"Custom", 
		each if [Customer]="A" then [Working days count] else if [Customer]="B" then [Calendar days count] else "0"
	)
in
	AddCustom

Copy paste this code to the advanced editor in a new blank query to see how the solution works. If this solution fits your need, copy and past a part of it and implement it in your query

Add a column

ColumnAdded = SWITCH(TableX[Customer],  "A", TableX[Working days count], 
                                        "B", TableX[Calendar days count],
                                      0)
