If AND formula help

Hi,

 

I have some data where I want to identify a break in the sequence of the data. I show the Excel formula that does this but I would like to have this calculation in Power Query but not sure how to write it?

 

In this instance I have identified that for this Item that 2022 is missing, it goes from 2021 - 2022 when the MSQ is greater than zero.

Hi @GordyM1 ,

According to your description, here's my solution.

1.Create a index column.

2.Create a custom column.

Custom = if [Index]=0 then "" else if [ItemID]=Table.SelectRows(#"Added Index",(x)=>x[Index]=[Index]-1)[ItemID]{0} and Table.SelectRows(#"Added Index",(x)=>x[Index]=[Index]-1)[MSQ]{0}>0 and [FY]-Table.SelectRows(#"Added Index",(x)=>x[Index]=[Index]-1)[FY]{0}>1 then "x" else""

Or you can create a calculated column in DAX.

Column =
VAR _T =
    FILTER ( 'Table', 'Table'[Index] = EARLIER ( 'Table'[Index] ) - 1 )
RETURN
    IF (
        'Table'[ItemID] = MAXX ( _T, 'Table'[ItemID] )
            && MAXX ( _T, 'Table'[MSQ] ) > 0
            && 'Table'[FY] - MAXX ( _T, 'Table'[FY] ) > 1,
        "x",
        ""
    )

Both methods can get the expected result.

This is possible to do in Power Query, but what do you plan to do with it once you have it? It might be better to just write a DAX measure and/or create a visual with your existing data that shows the missing year for that item. In the example below, I connected your data table to a simple date table with year (for the column values) and did a simple count of Items with the option of "Show Items With No Data" selected.

Hi Pat,

 

Thanks for the reply. Once I have identified the Item and Row where the gap is I go to my source data and make a manual entry so that there is no gap in the sequence. I currently do this in the excel table but wanted it done in Power Query (I have about 50K lines of data in the table). Not sure how to do a Dax measure?
