Need Solution for fetching Payment Details from Bills Collection

Hi Experts,

I am writing a collection for Cleared Bill, I need payment vouchers details like CostCente Class and Narration from the same collection

[Collection: ClearedPaymentBills]
Type : Bills
Fetch : *,*.*
Fetch : LedgerEntries.InventoryEntries.BatchAllocations.OrderNo
Cleared : Yes
Compute : PurcVchType : $$CollectionField:$VoucherTypeName:1:LedgerEntries
Compute : PurcPartyName : $$CollectionField@RemoteParty:1:LedgerEntries
Compute : PurcVCHNo : $$CollectionField@RemotePONum:1:LedgerEntries
Compute : PurcDate : $$CollectionField:$Date:1:LedgerEntries
Compute : PurcRefDate : $$CollectionField:$ReferenceDate:1:LedgerEntries
Compute : PurcPONum : $$CollectionField:$BasicPurchaseOrderNo:1:LedgerEntries

Compute : PartyPAN : $IncomeTaxNumber:Ledger:$Parent
Compute : PartyGSTNum : $LedPartyGSTIN:Ledger:$Parent
Compute : TDSTaxR : $$CollectionField:$TDSTaxRate:1:LedgerEntries
Compute : TDSLed : $$CollectionField@TDSLedger:1:LedgerEntries
Compute : TDSAmt : $$CollectionField@TDSAmount:1:LedgerEntries

 

Use like Below

Compute : BillNarration : $LedgerEntries[1,@@IsPaymentVch].Narration

 

It is not showing any result
My code is like this

[Collection: ClearedPaymentBills]
Type : Bills
Fetch : *,*.*
Compute : BillNarration : $LedgerEntries[1,@@IsPaymentVch].Narration

;select $Name,$Parent,$BillAmount,$OpeningBalance,$BillNarration from ClearedPaymentBills

 

you missed Cleared : Yes

 

This will fetch Narration Only from Payment Vouchers. So check Payment entry is there.?
