Dynamic Measure with Fieldparameters

Hello

 

I have some sample data here.

 

I have a D_Item with the article 12345, which has 4 values (Value 1 - Value 4)

 

In the fact table I have a few quantities for the article 12345.

 

The tables are linked via the ItemNo (D_Item 1 -> N F_Sales)

SUM of Qty = SUM(F_Sales[Quantity])

 

I would now like to write another measure:

The measure should calculate the SUM of Qty * the selected value from the field parameter)

 

I have tried this for this:

Test =

 

VAR _Selection = SELECTEDVALUE(FieldParameterPrice[FieldParameterPrice Fields])

 

RETURN

[SUM] * _Selection

 

As soon as I click on a value in the field parameter, I get the following error message:

 

Error retrieving data for this visual.

 

MdxScript(Model) (9, 9) Calculation error in the measure "D_Item"[Test]: The value D_Item[‘Value1’] of type "Text" cannot be converted to type "Number".

 

The fields Value1, Value2, Value 3 and Value 4 are datatype currency. Does anyone know why it does not work and has a solution?

    showy could you please use beow updated measure to get correct Grand Total.

    _Measure(Updated)2 = 
Var SelectedColumn = SELECTEDVALUE('PriceFields'[PriceColumn])

Var Result = 
SUMX(D_Item, 
    Var Quantity = CALCULATE(SUM(F_Sales[Quantity]))
    Var SelectedPrice = SWITCH (SelectedColumn,
                        "Price1", D_Item[Price1],
                        "Price2", D_Item[Price2],
                        "Price3", D_Item[Price3],
                        "Price4", D_Item[Price4],
                        BLANK())
    Var Result = Quantity * SelectedPrice //Final Result1
    Var Result2 = IF(ISBLANK(SelectedPrice), Quantity, Quantity * SelectedPrice) //Final Result2
    RETURN
    Result2 //Based on business needs chose any one result
    )
    
RETURN
Result

    showy ,

    This error is due to this [SUM] * _Selection. Here, you are trying to multiply a measure [SUM]  by _Selection which is a field reference not a number.

    Hi showy, 
    Wanted to let you know that Filed Parameters are return column reference (Value1, Value2, etc) not Numbers(3,00, 2,50, etc). To Fix this issue use SWITCH DAX logic as mentioned below.

    _Measure =
VAR SelectedField = SELECTEDVALUE('FieldParameterPrice'[FieldParameterPrice Fields])
VAR SelectedPrice =
    SWITCH (
        SelectedField,
        "Value1", SELECTEDVALUE(D_Item[Value1]),
        "Value2", SELECTEDVALUE(D_Item[Value2]),
        "Value3", SELECTEDVALUE(D_Item[Value3]),
        "Value4", SELECTEDVALUE(D_Item[Value4])
    )
RETURN
[SUM of Qty] * SelectedPrice

    Cthe message says D_Item['Value1] is text.

     

    This suggest that the data type is text.

     

    I want to help you but your description is too vague. Please write it again.


    You will get a quicker and better response without misunderstandings if you put time and effort into carefully writing a clear problem description with example input and output data. Look forward to helping you when this information is forthcoming


    * Please DON'T copy & paste your DAX that does not work and expect us to fathom what you want. (That is just crazy). ‌‌
    * Please DO give a simple non-technical functional description of what you want
    * Keep it simple and break large projects into smaller questions and ask just one question per ticket.
    * Rename columns to user friendly names. Avoid your own system jargon that we may not understand.
    * Most importantly please provide example input data as table text (not a screen print) so helpers can import the data to build a solution for you. (Learn how to share data below)
    * Provide the example desired output, with a clear step-by-step description of calculations and the process flow.
    * Take time and care to use the same table and field names in the input, output and description so we can understand your problem and help you.
    * Remove any unneeded tables, rows or columns which may cause confusion. Keep it short and concise with the minimal information regarding the key problem.
