Quality Notification number Range issue

Hi Friends,

I have one critical issue, where in for particular Quality notification type (R3),the number sequence has not been following,

Eg ; Notification 300001179 was created manually through QM01 after 300001175, then notification 300001176 was created and similarly

...1177,...1178,but then again notification 300001179,hence the notification is overwritten and this should not happen.

could you please suggest how to rectify the issue ( i need to raise OSS note or any relevant SAP notes needs to be applied)

and this has been occurring in Production system only and in Development and Quality we are not finding any issues.

please guide me.

Thanks in advance.

Regards,

Srinika.
