Writing DAX expression with multiple IF conditions (Excel to DAX-Power BI)

Question

I have this formula in Excel and I need it rewritten in DAX but I am unsure how to do this. I am very very new to DAX and so far have only been able to do the basics. I hope someone can help!

Excel Formula:

=IF([@[Date Shipped]]="","",IF([@[Date Exchanged]]="",[@[Date Shipped]]-[@[Date Approved]]+1,[@[Date Shipped]]-[@[Date Exchanged]]+1)-([@[Paused Days (Total)]]*([@[Paused Days (Total)]]<>"")))

My attempt with DAX, disastrous and clearly not correct:

Column = IF(ISBLANK('winnipeg erp_workorder'[Date Shipped]),BLANK(),IF(ISBLANK('winnipeg erp_workorder'[Date Exchanged]),('winnipeg erp_workorder'[Date Shipped]-'winnipeg erp_workorder'[Date Approved])+1),('winnipeg erp_workorder'[Date Shipped]-'winnipeg erp_workorder'[Date Exchanged])+1)-(IF(NOT(ISBLANK('winnipeg erp_workorder'[Paused Days Total],'winnipeg erp_workorder'[Paused Days Total]*'winnipeg erp_workorder'[Paused Days Total]))))

Thank you to anyone who can help!

Answer 1

It is difficult to provide exact solution without having the PBIX file because in DAX we have Measures and Columns so at the moment I am only guessing that everything that you have inside the code is coming from the columns.

You can use this and modify it to get to the desired result:

Column =
VAR DateShipped = 'winnipeg erp_workorder'[Date Shipped]
VAR DateExchanged = 'winnipeg erp_workorder'[Date Exchanged]
VAR DateApproved = 'winnipeg erp_workorder'[Date Approved]
VAR PausedDaysTotal = 'winnipeg erp_workorder'[Paused Days (Total)]
VAR Result =
    IF (
        NOT ISBLANK ( DateShipped ),
        IF (
            ISBLANK ( DateExchanged ),
            DateShipped - DateApproved + 1,
            DateShipped - DateExchanged + 1 - PausedDaysTotal
        )
    )
RETURN
    Result
