    Default Powerpivot Calculation column

    Hello,

    I have two tables in powerpivot and I need a calculation formula.

    Im new with the PowerPivot world so please be gentle with me.


    My data looks like that:

    table1:
    uniq order number | order price
    1 | 500$
    2 | 300$
    3 | 100$
    4 | 250&

    table2:
    order number | Time
    3 | 1.5
    3 | 2
    1 | 5.2
    2 | 2.33
    1 | 4.5
    4 | 1.22
    3 | 1


    I want to add a calculation column to table 2 that calculat the price for the relative record.
    for example: the first record in table 2 sould return 22.2222

    My calculation:
    100/(1.5+2+1)*(Time column - first row)

    * The "Time" column is the "time*24" (example: 02:30*24 = 2.5)


    Thank you!

    You should not write a calculated column. Read my article here Calculated Columns vs Measures in DAX - Excelerator BI

    Create a third table that contains all the unique order numbers. Join the 2 tables you have already to the new table. Create a pivot table and place the order number from the new table in the pivot on rows.

    I can't understand the logic of your formula as written, but you can write a measure something like this

    =sum(table2[time]) *max(table1[order price])
