Dynamically filter last row per item

My 'Fact_Booking' table holds a log of every time a [Sales_ID] changes. I therefore have multiple rows per [Sales_ID] as sales are confirmed / revised / cancelled etc.   I would like to be able to ...

    You could try

    Sum of last rows =
VAR ChosenDate =
    MAX ( 'Date'[Date] )
VAR SummaryTable =
    CALCULATETABLE (
        INDEX (
            1,
            'Fact booking',
            ORDERBY ( 'Fact booking'[Last modified date], DESC ),
            PARTITIONBY ( 'Fact booking'[Sales ID] )
        ),
        'Date'[Date] <= ChosenDate
    )
VAR Result =
    SUMX ( SummaryTable, 'Fact booking'[Sales value] )
RETURN
    Result

    This makes a few assumptions. Firstly that your date table is linked to your fact table on the last modified date. Secondly, you will need a unique identifier for each row in fact booking. If you don't have one naturally you can add an index column using power query. Make sure that the unique column is marked as the key column in the modelling view, that will stop INDEX complaining that the table may have duplicates.

Hi, I am trying to produce something similar but this is not working for me at all .  I am told index is not a function?

 

I have an updates table that update a user status from approved, not approved in categories one and category 2. I also have a calendar table

e.g.

 

User nameCategory 1Category 2Created on
user 2approvednot approved5/1/23
user 1approvednot approved3/1/23
user 2 approvedapproved2/1/23
user 1not approvedApproved1/1/23
user 3not approvedapproved2/1/23

 

I would like to be able to display a bar chart with a date slider that can show for example the countof category one approved users on a chosen day...so if I filter to 4/1/23 then the count for category 1 approved user would be 2 (users 1and 2) and the count for category 1 not approved would be 1 (user3), count category 2 approved 2 (users 2 and 3), category 2 not approved 1 (user1) as it would only take into account the latest record for a user not the ones previously.  So data table filtered to 4/1/23 as below

UserNameCategory 1category 2latest Created on
user 2approvedapproved2/1/23
user 1approvednot approved3/1/23
user 3not approvedapproved2/1/23

 

and bar  chart as 

 

So far I have this measure w

Measure =
CALCULATE(FIRSTNONBLANK(new_partnerlandscapehistory[createdon],1),
FILTER(new_partnerlandscapehistory,new_partnerlandscapehistory[createdon] = MAX(new_partnerlandscapehistory[createdon])))
 
which manages to give me the last record up to that date in a table but can't get this to work with a count in barchart as then it counts the previous records also

 

 

thanks for your help 🙂
