## DAX calculation with previous calculated value

Hi,

I have 3 different tables:

Production forecast (year 2021-2030)

Sales forecast (year 2021-2030)

Available stock (current 2021)

How can I calcultate the forecast of the stock for next year with a DAX calculation?

For example: Forecast stock 2022 should be:  available stock 2021 + production forecast 2021 - sales forecast 2022

Forecast stock 2023 should be:  forecast stock 2022 + production forecast 2022 - sales forecast 2023

I've managed to calculate the first line

Forecast stock = SUM('Stock'[Quantity])+ [Production forecast last year]-[total sales forecast in year)
How can I use the calculated forecast stock value for the second line?

@meskens Yes, that helps a lot. Unfortunately, there is no clean way of doing this sort of thing in DAX as DAX does not really support previous value/recursion. Previous Value aka "Recursion" - Microsoft Power BI Community

Thank you for the answer. Then I will have to find a other way to make this happen.

@meskens Sorry, having trouble following, can you post sample data as text and expected output?
Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

Would this be of any help?

Stock forecast 2022 would be Stock Quantity 2021 + Prod forecast Quantity 2021 - Sales Forecast Quantity 2022

Stock forecast 2023 would be Stock forecast 2022 + Prod forecast Quantity 2022 - Sales Forecast Quantity 2023

 Table name Date Prod forecast Sales forecast Stock Column name Year Quantity Quantity Quantity Stock Forecast (to be calculated) 2021 4.844.683 7.697.000 24.629.251 2022 4.264.317 7.000.000 22.473.934 2023 2.208.508 7.000.000 19.738.251 2024 - 7.000.000 14.946.759 2025 2.147.410 7.000.000 7.946.759
