Advocate IICreate new table with last complete record for each Unit
Advocate IIUnfortunately it is the ties in the [Lastchanged] column that is causing the TopN to return more than 1 row for some DUID.
Would be useful if there was a parameter in TopN to explicitly return 1 row only - something similar to the RankX.
Tried wrapping the function in LastNONBlank to explicitly return only 1 row, but this doesn't appear to work, probably something to do with operation on a column argument rather than a complete table row.
For me, its quicker to simply export the 616 of 678 table out and remove the highlighted duplicates in excel.
Kudo CollectorI don't know if it is ok for you to create an auxiliary column, but if it is ok, here is my solution:
Create the ISMAX column to check if it is the last record.
Then, create your virtual table with DISTINCT of only "Yes".

ISMAX =
VAR DUID = Tabela1[DUID]
VAR MAXDATE =
CALCULATE (
MAX ( Tabela1[LASTCHANGED] );
ALL ( Tabela1 );
Tabela1[DUID] = DUID
)
RETURN
IF ( Tabela1[LASTCHANGED] = MAXDATE; "Yes"; "No" )UniqueDUID =
CALCULATETABLE ( DISTINCT ( Tabela1 ); Tabela1[ISMAX] = "Yes" ) - pat_energetics
Thanks zapppsr, I thought your function would work.
When I filter the original table on the ISMAX column = "Yes" , it still returns 678 values (of which 616 are unique)
When I use the CALCULATETABLE with filter on the ISMAX, it still returns 678 records - with 616 unique.
The issue is due to the ties in the [LASTCHANGED] for some DUID, which is an issue in the source that cannot be changed.
In the meantime I have fixed the duplicates in excel.
Thanks for trying !
- zapppsrI guess the tie is on a combination of other columns beside DUID and LASTCHANGED, because I treated the tie for those two columns. Have you considered testing creating a table with only those columns?
