Calculate variable with if statement based on date without value

[rsanyoto]

Hello everyone,

Im kinda new to the DAX and im struggleing to calculate the final cost price of a product based on some variables.

What i have fixed is following:

1. So if there is a transaction that has a posting date that has a value between startingdate and endingdate then the Variable CostPriceWithDate will solve this.
   
   
2. The final cost price for a product with a date is calculated in variable FinalCostPriceWithDate . 
   
   
3. Ifthere is no value on the column  (Dim_PurchasePrice[EndingDate])  (see the Variable NoDate) then calculate the variable CostPriceWithoutDate. The final cost price for a product without a date is calculated in variable FinalCostPriceWithoutDate.

The requirement is: if there is no value in the column Ending Date (see image below) then use the variable FinalCostPriceWithoutDate , otherwise use the variable FinalCostPriceWithDate .

My question is how to return the correct value (based on the underneath Dax) if there is no data in a column Ending Date (see image below)  I think the part of Var NoDate and my Return statement is not correct. Please help. 

Kind regards 

Totaal  CostPrice Products =

VAR Date =

    MAX ( Fact_ValueEntry[PostingDate] )

VAR NoDate =

MIN (Dim_PurchasePrice[EndingDate])

VAR Product =

    MAX ( Fact_ValueEntry[ItemFK] )

VAR CostPriceWithDate =

    CALCULATE (

        MAX ( Dim_PurchasePrice[DirectUnitCost] ),

        Dim_PurchasePrice[ItemFK] = Product,

        Dim_PurchasePrice[StartingDate] < Date,

        Dim_PurchasePrice[EndingDate] >= Date

    )

VAR CostPriceWithoutDate =

    CALCULATE (

        MAX ( Dim_PurchasePrice[DirectUnitCost] ),

        Dim_PurchasePrice[ItemFK] = Product,

        Dim_PurchasePrice[StartingDate] < Date,

        Dim_PurchasePrice[EndingDate] = NoDate)

VAR CostPriceInk =

    CALCULATE (

        max ( Dim_PurchasePrice[DirectUnitCost] ),

        Dim_PurchasePrice[ItemFK] = "INK")

VAR CostPriceGlue =

    CALCULATE (

        max ( Dim_PurchasePrice[DirectUnitCost] ),

        Dim_PurchasePrice[ItemFK] = "GLUE")

VAR FinalCostPriceWithDate = CostPriceWithDate + CostPriceInk + CostPriceGlue

VAR FinalCostPriceWithoutDate = CostPriceWithoutDate + CostPriceInk + CostPriceGlue

RETURN

  IF(ISBLANK(NoDate), FinalCostPriceWithoutDate, FinalCostPriceWithDate))

hi everyone & @HotChilli,

My collegeau and i have solved the issue for the requirement. the main root cause is the data type of the column EndingDate which has records with value 1753/01/01. After initial load to Power BI file, this record is treated as a date. This created a mismatched with my variables in the measure.  So i changed in my SQL view with nullif statement to make the records as BLANK. 

 The following dax code works :

Total CostPrice Products =

VAR WithDate =

MAX ( Fact_ValueEntry[PostingDate] )

VAR NoDate =

MIN (Dim_PurchasePrice[EndingDate])

VAR Product =

MAX ( Fact_ValueEntry[ItemFK] )

VAR StartingDatePurchase =

CALCULATE(MAX(Dim_PurchasePrice[StartingDate]),

Dim_PurchasePrice[StartingDate] <= WithDate)

VAR CostPriceWithDate =

CALCULATE (

MAX ( Dim_PurchasePrice[DirectUnitCost] ),

Dim_PurchasePrice[ItemFK] = Product,

Dim_PurchasePrice[StartingDate] = StartingDatePurchase,

NOT( Dim_PurchasePrice[ItemFK] IN {"INKT","GLUE"})

)

VAR CostPriceInk =

CALCULATE (

MAX ( Dim_PurchasePrice[DirectUnitCost] ),

Dim_PurchasePrice[ItemFK] = "INKT")

VAR CostPriceGlue =

CALCULATE (

max ( Dim_PurchasePrice[DirectUnitCost] ),

Dim_PurchasePrice[ItemFK] = "LIJM")

RETURN

CostPriceWithDate + CostPriceInk + CostPriceGlue

Can you provide a test pbix please because it's a bit difficult to debug this without seeing the model/relationships?

Just fake a small example (and provide the desired result please)   and link it from an external site and I'll have a look for you

Hi @HotChilli ,

I have uploaded the pbix example in my public github repository. Download the file of 2,19 mb
