Count number f order without to count cancelled order

[AudeVazart]

Hello,

I am new in power bi and I really need your help.

I have one column with Order ID and one column with order value.

I need to count the number of order based on Order ID but without to take into consideration the cancelled order.

An order cancelled wil have the same Order ID but the value will be negative.

Example:

Order ID: 123 / Order Value: 100$

Order ID: 123 / Order Value: -100$ (order cancelled)

In this example, my order count will 0.

I try to find a measure to reflect the logic above but without any sucess.

thanks.
