I put the following formula, calculation works. when highlighted this field to "Sum (total)", it show is "Move" instead "instert summary". Any tips please to "insert summary" (want to total this field). Thanks,
if {JCT_CURRENT__TRANSACTION.Accounting_Date} = maximum({JCT_CURRENT__TRANSACTION.Accounting_Date})
then
tonumber({JCT_CURRENT__TRANSACTION.Amount})
if {JCT_CURRENT__TRANSACTION.Accounting_Date} = maximum({JCT_CURRENT__TRANSACTION.Accounting_Date})
then
tonumber({JCT_CURRENT__TRANSACTION.Amount})
