Comparing Dates (Slippage) vs current Go Live Date Month

HI all,   I have the table below showing CUID Number (=project number), GLD (Go Live Date) and the GLD that had this project in prev months. What I am trying to achieve is to track the changes ...

    Thanks for attaching the report.

    Change the period column to type text then this measure works

    Previous Period Changed? =
    var _currentPeriod =
    SELECTEDVALUE(RPT10[Period])
    var _currentGLD =
    FORMAT(SELECTEDVALUE(RPT10[GLD]), "YYYY-MM")
    var _prevPeriod =
    FORMAT(EOMONTH(_currentPeriod,-1), "YYYY-MM")
    var _prevGLD =
    FORMAT(LOOKUPVALUE(RPT10[GLD],RPT10[Period Column],_prevPeriod, RPT10[CUID], SELECTEDVALUE(RPT10[CUID])), "YYYY-MM")
    Return
    IF(
        // test for beginning for date list
        ISBLANK(_prevPeriod) || _prevPeriod = "",
        "No Change",
        IF(
            _currentGLD = _prevGLD,
            "No Change",
            "CHANGED"
        )
    )

    CALCULATE(
    MIN(RPT10[GLD]),
    ALLEXCEPT(RPT10, RPT[CUID])
    )

    should pull the earliest date for each CUID

    You should be able to change the Initial GLD Changed measure to

    Inital GLD Changed = 
    SWITCH(
    TRUE(),
    RPT10[GLD] = [Earliest GLD], "No Change",
    DATEDIFF([Earliest GLD], RPT10[GLD], MONTH) >=3, "Changed +3",
    DATEDIFF([Earliest GLD], RPT10[GLD], MONTH) <3, "Changed"

    )

I am not sure that I 100% understand the outcome you are looking for but

I created a small dataset based on your example as follows

Using that data I made the following measure

Previous Period Changed? =
var _currentPeriod =
SELECTEDVALUE(gldTable[Period])
var _currentGLD =
FORMAT(SELECTEDVALUE(gldTable[GLD]), "YYYY-0M")
var _prevPeriod =
FORMAT(DATEADD(gldTable[Period],-1,MONTH), "YYYY-0M")
var _prevGLD =
CALCULATE(values(gldTable[GLD]),gldTable[Period Column]=_prevPeriod)
Return
IF(
    // test for beginning for date list
    ISBLANK(_prevPeriod) || _prevPeriod = "",
    "No Change",
    IF(
        _currentGLD = _prevGLD,
        "No Change",
        "CHANGED"
    )
)
and ended up with this

Hope this helps.

Thanks jgeddes,

 

Thanks for your answer. That looks good. I see that you combined all dates column in one column called period.

The thing is that every month I will get the excel file like the one below:

One column with dates for every month. 

 

 

Tried different ways to Merge/Group to move all dates in one column based on CUID and create your "period column" but it seems I am unable to do it.

    In the format you have you will need to unpivot the columns in Power Query and then you will be able to add the Period column. The period column I created was just done with DAX. FORMAT(gldTable[Period[, "YYYY-MM")

      Thanks for the Help. I unpivoted the columns in Power Query I created the columns like your screenshot.

       

       

      but is not working. 

      It says something about Dax comparison operations do not support comparing values of type Date with Text values but I updated all the fileds involved to Date format.

       

      Attached a report in case it helps.

      hi @jgeddes,

       

      Quick question regarding this report

       

      As discussed previously, my data source is the Excel below.

      Report is monthly and "Actual GOLIVE" column always uses the most updated go Live Date in the file. (see example below). That means that I cannot use the "Actual Go live Data columns" as the "Original Go Live Date"

       

      Is it possible to create a measure that takes the earliest date (that we can use as the Original Go Live Date) and compare with the changes?

       

      Tried

      Earliest GLD = MIN(RPT10[GLD]) but it's showing the same data as the month date.

      For example first Row (CUID 380305KR01) 

      Original Go Live Date should be: Jun-2022

      Same date for CUID 380305MX01

       

      thanks

        CALCULATE(
        MIN(RPT10[GLD]),
        ALLEXCEPT(RPT10, RPT[CUID])
        )

        should pull the earliest date for each CUID
