Burada Alt Sorgu İfadelerine İzin Verilmez Hatası

[selamf]

Arkadaşlar Merhaba
Hazırlamış olduğum bir SQL sorgusunda burada alt sorgulara izin verilmez uyarısı alıyorum
Yardımcı olabilir misiniz hata nereden kaynaklanıyor ?

Sorgu bu;
SELECT SUM (ai.amount * ai.status),
(SELECT SUM (ai2.amount * ai2.status) tutar
FROM sms.cs_account_action aa2
JOIN sms.cs_Account a2
ON (aa2.account_id = a2.id)
JOIN sms.cs_Account_income ai2
ON (ai2.account_action_id = aa2.id)
JOIN sms.cs_Action_Type_prm atp2
ON (atp2.id = aa2.action_type_id)
WHERE aa2.id = aa.id AND atp2.TYPE = 2)
FROM sms.cs_account_action aa
JOIN sms.cs_account a
ON (aa.account_id = a.id)
JOIN sms.cs_account_income ai
ON (ai.account_Action_id = aa.id)
JOIN sms.cs_action_type_prm atp
ON (atp.id = aa.action_type_id)
WHERE a.installation_id = 1 AND atp.TYPE = 1
GROUP BY (SELECT SUM (ai2.amount * ai2.status) tutar
FROM sms.cs_account_action aa2
JOIN sms.cs_Account a2
ON (aa2.account_id = a2.id)
JOIN sms.cs_Account_income ai2
ON (ai2.account_action_id = aa2.id)
JOIN sms.cs_Action_Type_prm atp2
ON (atp2.id = aa2.action_type_id)
WHERE aa2.id = aa.id AND atp2.TYPE = 2)
