I need help to calculate a new column i Visual Studio.
My data table includes turnover per ordernumber (multiple lines per ordernumber) and it inlcudes data for 2 months (current and next month). The new column should show the turnover if the ordernumber exist in next month - if the ordernumber only exists in current month the turnover should be 0. What to do???
Thanks a lot in advance.

What do you mean "calculate a new column i Visual Studio"? I assume you want to create a calcualted column within Power BI Desktop.
In this scenario, you must make sure the 2 months dates contiguous. You can use lookupvalue() to check the existence of same date in next month. Please try formula below:
Column = IF( LOOKUPVALUE(Table[OrderNumber], Table[Date], PARALLELPERIOD(Table[Date],1,MONTH))=BLANK(), 0, CALCULATE(SUM(Table[TurnOver]), ALLEXCEPT(Table,Table[OrderNumber])) )
