It is InventJournalTrans.
You already have the voucher information. You need to look it from inventory transactions related to the counting journal lines. On transactions , ledger → Financial voucher.
Thanks for the reply Kranthi,
but i need one button for this form InventJournalCount , when i click this button corresponding LedgerTransVoucher form records should be displayed
I am not sure why do you need it, when you already have it on transactions.
Anyway, you can look at other forms where there is same functionality. Example - CustInvoiceJournal, InventTrans etc…
Look at \Forms\LedgerTransVoucher\Methods\init. Look how the changes are done for other sources.
You need to consider the voucher on InventJournalTrans table.
