Consider the Following Power BI dashboard Model :
We have 3 tables
Table 1 : EM table
There are no duplicate rows in the table.
Table 2 : Norm Table
MaxUpdateFlag1 - is calculated columns
In the table, the below columns are used as filters to obtain the unique value for R_Val.
Cuc ,Date, DMA_Date,P_P,P_T,GT1, R_D
Also, the below columns are used as filters to obtain the unique value for S_Val and T_Val.
Cuc, Date, DMA_Date
Code for MaxUpdateFlag1
MaxUpdateFlag1 =
Var CurrentRow = 'Norm'[DMA_DATE]
VAR MaxUpdate =
CALCULATE(
MAX('Norm'[DMA_Date]),
ALLEXCEPT( 'Norm',
'Norm'[EMID],
'Norm'[DATE],
'Norm'[P_P],
'Norm'[CUC],
'Norm'[GT1],
'Norm'[P_T],
'Norm'[R_T],
'Norm'[R_D]
)
)
RETURN IF(CurrentRow = MaxUpdate, 1, 0)
The third Table is Dates, it is a calculated table with the following code :
Dates = CALENDAR (MIN('Norm Table' [DATE]), MAX('Norm Table' [DATE]))
This is how tables interact together on the relationship model,
EM Table is joined to Norm Table using Column EMID
The relationship is One(EM Table) to Many (Norm Table) in cardinality
Cross-filtering is set to both.
Norm Table is joined to the Dates Table using the Date column
The relationship is One(Dates) to Many (Norm Table) in cardinality, and cross-filtering is set to one-directional.
The matrix visual has the following information in order:
Rows :
E_ID from EM table
EName from EM table
R_D from Norm table
S_Val from Norm table
T_Val from Norm table
Columns :
P_P from Norm Table
R_T from Norm Table
Values :
R_Val from Norm table
In the Filter on this visual section of the matrix
The MaxUpdateFlag1 column from the Norm Table has been added, value is set to 1.
The Idea for setting up the column value to 1 is to display the latest R_Val, S_Val, and T_Val based on the latest information-based DMA_Date Column.
I am looking to change MaxUpdateFlag1 to a measure.
I have a large dataset and a calculated column is not feasible.
