DAX calculated column for any location <0

[shophoney]

Hi, I need help on creating a calculated column and or measure for any location where the OH is less than 0.

I have a table with OH and location in the next column.

But I need to list any models where and location has a qty OH less than zero. I want to see all locations OH so I can see if there is a transfer error or a sales error.

I could then use the calculated column saying "OH Error" and filter those results.

Thanks
