update custom fields in BankAccountTrans from LedgerJournalTrans during the posting of journal in D365FO

 update custom fields in BankAccountTrans from LedgerJournalTrans during the posting of the journal in D365FO. Here I am writing the code in the insert method for this I have used a pre-event handler. Check the below code.

class BankAccountTrans_Events
{
    [PreHandlerFor(tableStr(BankAccountTrans), tableMethodStr(BankAccountTrans, insert))]
    public static void BankAccountTrans_Pre_insert(XppPrePostArgs args)
    {
        BankAccountTrans    bankAccountTrans = Args.getThis();
        LedgerJournalTrans  ledgerJournalTrans;

        if (bankAccountTrans.SourceRecId && bankAccountTrans.SourceTableId 
                && bankAccountTrans.SourceTableId == tableNum(LedgerJournalTrans))
        {
            select firstonly1 ledgerJournalTrans
                where ledgerJournalTrans.RecId == bankAccountTrans.SourceRecId;

            bankAccountTrans.NewField1 = ledgerJournalTrans.NewField1;
            bankAccountTrans.NewField2 = ledgerJournalTrans.NewField2;
        }
    }
}

Keep daxing!!
