Convertion of expression in load script

[vikasmahajan]

Dear all

I have following expression this I want to convert into script

SUM(AGGR(((SUM({$<FinancialYear=,Quarter=,MonthName=,[Posting Date] ={"<=$(=MonthEnd(Max([Posting Date])))>=01/04/2012"},[Inv Flag]={0,1,3,5}>}QTY_SIGNED) /* Closing Qty of prev month*/

-

SUM({$<FinancialYear=,Quarter=,MonthName=,[Posting Date] ={"<=$(=MonthEnd(Max([Posting Date])))>=01/04/2012"}>}[Sales Invoice Qty]) /*sales Qty from 1/4/12 till date*/

-

SUM({$<FinancialYear=,Quarter=,MonthName=,[Posting Date] ={"<=$(=MonthEnd(Max([Posting Date])))>=01/04/2012"}>}[Sales Bonus Qty]) /*sales Bon Qty from 1/4/12 till date*/

+

SUM({$<FinancialYear=,Quarter=,MonthName=,[Posting Date] ={"<=$(=MonthEnd(Max([Posting Date])))>=01/04/2012"},[Sales Return Type Code]={0}>}[Sales Return Qty]) /*sales Ret Qty from 1/4/12 till date*/

+

SUM({$<FinancialYear=,Quarter=,MonthName=,[Posting Date] ={"<=$(=MonthEnd(Max([Posting Date])))>=01/04/2012"},[Sales Return Type Code]={0}>}[Sales Return Bonus Qty]) /*sales Ret Bon Qty from 1/4/12 till date*/

)

*avg([Stat Rate Inv]))/100000,[Product Batch Code],[Location Code],[Product Code],[Expiry Date]))

How to achieve the same ?
