GROUP BY Ten.Account,ten.DCBalance,MRD.fPreviousReading, MRD.fCurrentReading, MRD.fConsumption, T.cDescription

Answer 1

As I don't know your data, there is a possibility I wrote you a code that would return some double rows. But that is a problem you can easily handle.
Try it, nevertheless:
SELECT t1.Account,
t1.Balance,
t1.BilledAmount,
t1.fPreviousReading,
t1.fCurrentReading,
t1.fConsumption,
t2.cDescription
FROM (SELECT Ten.Account,
ten.DCBalance AS Balance,
SUM (T.fInclusiveAmount) AS BilledAmount,
SUM (MRD.fPreviousReading) AS fPreviousReading,
SUM (MRD.fCurrentReading) AS fCurrentReading,
SUM (MRD.fConsumption) AS fConsumption
FROM _mtblTransactions T
left join _mtblProperties P ON P.idProperty = T.iPropertyID
left join Client Ten ON T.iCustomerID = Ten.DCLink
left join Client Own ON P.iPropertyOwnerID = Own.DCLink AND oWN.Account='11074'
left join _etblPeriod PER ON T.iPeriodID = PER.idPeriod
left join _mtblMeterReadingDetails MRD ON T.iMeterID = MRD.iMeterReadingsMeterID and T.iPeriodID = MRD.iBillingPeriodID
and MRD.iReadingType=0
and idPeriod='79'
GROUP BY Ten.Account,ten.DCBalance) t1
JOIN (SELECT T.cDescription,
Ten.Account,
ten.DCBalance
FROM _mtblTransactions T
left join Client Ten ON T.iCustomerID = Ten.DCLink) t2 ON t2.Account = t1.Account AND t2.DCBalance = t1.DCBalance
