Running calculation

[TrevorPhilips]

Hello Power BI Forum,

I oftern visited this site for help and today I was facing a problem where I could not finde a solution. I tried something like "calculate from above row" or "running totals", but that doesnt help.

I need a calculation, which shows the current amount of products in storage. There can be old/used or new products. If a product is sold, first the storage with old/used product shall decrease, if the old/used storage is 0, then the storage with new products. Is there any idea to solve this power query?

Here an explanation:

Thanks for some ideas.

Best,

Trevor
