Relative Reference

[Anonymous]

I am trying to write a formula for PowerQuery that looks at a cell value and if it equals a specified value retuns the value of a cell that is in the next row and over one column. I want this value to be returned in its own column and if it does not match it should return a 0. 

Here is a link to a sample PBIX.

Since i could not get the ref to work i ended up doing the following

Adding two Index columns one starting with 0 the other with 1

Doing a merge table with itself and refrencing the two index columns. this shifted the time values to the same line as the Action and then it became a simple if statment without the ref. 

Thanks all for the ideas& help on this one!

Hi Frunkis,

You can use measure instead, try DAX below and check if it can meet your requirement:

Result =
VAR previous_time =
    CALCULATE (
        MAX ( ReportA06272018[Total Agents Needing Help] ),
        FILTER (
            ALL ( ReportA06272018 ),
            ReportA06272018[Index.1]
                = MAX ( ReportA06272018[Index.1] ) - 1
        )
    )
VAR previous_state =
    CALCULATE (
        MAX ( ReportA06272018[Action] ),
        FILTER (
            ALL ( ReportA06272018 ),
            ReportA06272018[Index.1]
                = MAX ( ReportA06272018[Index.1] ) - 1
        )
    )
RETURN
    IF (
        previous_state = "Release (Not Ready)",
        MAX ( ReportA06272018[Total Agents Needing Help] ) - previous_time
    )

So far I have gotten to 

= Table.AddColumn(#"Added Index1", "NotReady", each if [Action] = "Release (Not Ready) " then {[Index1]+1}[Time] else null)

This is not working and I am not sure why. Anyone have any pointers?

I keep getting the following error with the above formula:

Expression.Error: We cannot apply field access to the type List.
Details:
Value=List
Key=Time

Any ideas on how to resolve this?

I have been using excel to do this function for a while and i can just have a formula that is "=if(c7='Release (Not Ready)', D8,0) and it works great. I am trying to make the change to Power BI because it offers alot of functions that Excel doesnt.. any help would be met with great enthusiasm.

I do have an "Index" column that I added when trying to figure this out. It starts at a count of 1.
