HELP WITH DAX: Simulate Excel What-If-Analysis Goal Seek

Hello everyone, 

I need help with one DAX. Actually, I need something that is in excel called 'What-If-Analysis/Goal Seek' .

I would try to explain problem: 

 

I have two known components - example stock (I will name it A) and sales (I will name it B), at the moment. 

And I have ratio between them as end of period goal (I will name it GOAL).

My unknown component, the one I need help with, is forecast sale by the end of the period (I will name it X). 

A / B = CURRENT RATIO

 

(A-X) / (B+X) = GOAL 

 

X = ? 

 

If you think you can help me, you can ilustration in excel:

Thanks in advance, 
Alex

Hi @astojanac ,

 

1.You can make current ratio as a measure: 

 

measure=Devide(MAX(A),MAX(B))

 

 

2.Then convert your X expression as below:

x=Devide((A-Goal*B),(Goal+1))

Hello @amitchandak ,

 

Thank you for your answer.
I know for What-if parameter, but I can't find the way to use it in my case when I have unknown value in two places at the same time.
