how to inactive/invisible a field or line- see code

dear experts ,
the field purled should be display when the vouchertype is receipt note or under receipt note.

[#Part: EXPINV InvInfo]
add: Lines :Before : EXPINV InvDetails urled

[#Part: ExciseMfgrInv InvInfo]
add: Lines :Before : ExciseMfgrInv InvDetails : purled

[Lineurled]
Fields: simple field,purled
Local:Field:simple field:Info:"Account Head :"

[Fieldurled]
Set as: $$PrevLedger@IsInward:$StockItemName

 

There are basically Two methods for your query.
1.
You can set any of the voucher types for making it invisible to that particular voucher type.
[Lineurled]
Fields: simple field,purled
Local:Field:simple field:Info:"Account Head :"
Invisible : $$IsSales:##SVVoucherType or $$IsContra:##SVVoucherType or $$IsReceipt:##SVVoucherType or +
$$IsDebitNote:##SVVoucherType or $$IsCreditNote:##SVVoucherType or $$IsPayment:##SVVoucherType or +
$$IsMemo:##SVVoucherType or $$IsRevJrnl:##SVVoucherType or $$IsStockJrnl:##SVVoucherType or +
$$IsPhysStock:##SVVoucherType or $$IsDelNote:##SVVoucherType or $$IsRcptNote:##SVVoucherType or +
$$IsRejIn:##SVVoucherType or $$IsRejOut:##SVVoucherType or $$IsSalesOrder:##SVVoucherType or +
$$IsPurcOrder:##SVVoucherType ;;or $$IsJournal:##SVVoucherType

 

2. You can set Option at part level.

[#Part: ExciseMfgrInv InvInfo]
option : purled : $$IsReceipt:##SVVoucherType
