Problem in walk collection for LedgerEntries in current report

I wanted to walk collection of current report like daily report to LedgerEntries but my filter is not working is their is any way to solve this problem or any alternet way to solve this

Code:

[System:Formula]
    FilerMasterID :$$AsReqObj:$$FilterValue:$MasterID:CrrMstIDcoll:First  ;;this is broken not working

[Collection : CrrMstIDcoll]
    Data Source : Report : All
    Fetch : MasterID

[Collection : CurREPTcoll]
    Type : Voucher
    Fetch : *, InventoryEntries.*, AllLedgerEntries.*
    Filter : newfilterpp
   
[Function:StrtGenMSGV2]
    Variable:vchnumoflg:String
    01 : WALK COLLECTION : CurREPTcoll
    02 : Set:vchnumoflg: $$String:$VoucherNumber
    03 : WALK COLLECTION :LedgerEntries
    04 : Log:$$String:##vchnumoflg + " | " + $$String:$LedgerName
    05 : END WALK
    06 : END WALK
    07 : Log:$$String:"---END---"

 

Sorry to say, but what you want to do with above code? prima facie it seems that you want to gather ledger name from collection CurREPTcoll through function. and you will get also.
Elaborate your question properly I will try to answer you...
