Hi.

I have got a BR as follows:-

 

FIX ("CVR Amount",&CurrentYear, "CVR",&CurrentMonth,{CVR_CostCenter},{CVR_Projects}, "No Company", {CVR_SBU}, "No Intercompany", "No Spare", "Default Elements",@Relative("Total Line Items",0),"No Future1", "No Future2","Current Period as per Accounting System")

SET CREATENONMISSINGBLK ON;

    "CVR Working"(

      IF("Value Method"->"No Line items"->"CVR Details Account Member"->"No Elements" <> #MISSING)

            IF("Value Method"->"No Line items"->"CVR Details Account Member"->"No Elements" == 1) /* Cost Plus Fee Method*/

 

"Cumulative Cost for Cost Plus Fee Method"->"Default Elements" = "Total Cost to Date"->"All Elements";
