ALTER trigger [dbo].[tr_ledgerdelete]
on [dbo].[BCDet]
after delete
as
begin
    SET NOCOUNT ON;

    update t
    set totcr = t.totcr - d.amt
    from accmast t
    inner join deleted d on t.lcode = d.lcode
    where d.dc='C'

    update t
    set totdr = t.totdr - d.amt
    from accmast t
    inner join deleted d on t.lcode = d.lcode
    where d.dc != 'C'

    update t
    set clbal = t.totcr - t.totdr + t.opbal
    from accmast t
    inner join deleted d on t.lcode = d.lcode
