ignore values less than zero

[eburke]

Hi guys,

I'm pretty sure this should be a simple one but I can't find an answer to it searching.  I have a very simple measure:

Customer Assigned - PrePaid Hours = Billable Hours

The Prepaid Hours is a set amount and the Customer Assigned hours is the number of hours they have used in a month, I want to calculate the Billable Hours i.e. number of hours they have used in a month ABOVE their set PrePaid hours.  The formula above is fine except for when they have used less than their PrePaid Hours and therefore it gives a negative figure:

CA 1 hour - PrePaid 1.5 Hours = Billable -.5 hours

What I'm after is a formula that states if the value is a negative change it to 0:

CA 1 hour - PrePaid 1.5 = 0

Thanks,

Hi @eburke

You should be able to use the IF function for this.

= IF ([Customer Assigned] - [PrePaid] < 0 , 0 , [Customer Assigned] - [PrePaid] )

HI @eburke

Just wrap a SUMX Function around it to force the Total calc to be row by row

Measure 2 = 
	SUMX(
		'Table2',
		IF(
			'Table2'[Customer Assigned]-'Table2'[Pre Paid]>0,
			-- THEN --
			'Table2'[Customer Assigned]-'Table2'[Pre Paid],
			-- ELSE --
			0)
			)

Thank you, I thought it was something like that I just had my brackets in the wrong place. 

My issue now is how do I apply that to the Totals at the bottom of the table, otherwise it does Total CA - Total PrePaid = Billable Hours, whereas I actually want to show the column total of Billable Hours

When I try this formula the THEN and ELSE come up green like Power BI doesn't recognise it as a function.  Also will it matter that the Customer Assigned and PrePaid Meaures are on different tables?  Thanks,

Bwahahaaa... excuse me while I hang my head in embarrassment.  Thanks you that worked brilliantly.
