PQL Equation to Find Difference between Dates is Returning both Positive and Negative Values

[alanphamvistra4]

I have the follwing Custom Column Equation:

if [Overall Status] = "Submitted for Review" then DateTime.LocalNow() - [Submit Date] else [Review Date] - [Submit Date])

All of the Submit Dates are in the past, so I should get only positive values or 0. Some of the records are returning negative values even when the Submit Date is years in the past. How can I fix it to only return postive values?

Hi @alanphamvistra4 ,

You can create a calculated column as below to get it, please find the details in the attachment.

Difference = 
VAR _days =
    IF (
        'Table'[Overall Status] = "Submitted for Review",
        DATEDIFF ( 'Table'[Submit Date], TODAY (), DAY ),
        DATEDIFF ( 'Table'[Submit Date], 'Table'[Review Date], DAY )
    )
RETURN
    IF ( _days < 0, BLANK (), _days )

If the above one can't help you, could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution.
