Calculate cumulative difference total

[cristianml]

Hi,

I need to create a measure (called "Inventory") to calculate in power BI the following formula as you see in Excel :

Inventory = Last period Inventory + Revenue - Billings

I have the categories "Billings" and "Revenue" in the same column (Category Group). 

Any Ideas ?

Thanks and regards,

Hi @v-chuncz-msft ,

Is not the same Solution. In this case I have to calculate a difference and then acumulate it with previous period. Follow the screenshot:
