QM notification doc range issue-QM11-Range is not in seq with creation date

Hello Experts,

I have a strange ,yet intresting issue

Issue :This is in regards to issue with quality notification number getting recycling(I.e the range is not in sequence with the creation dates)

That is for example in PRD (Production)

Transaction Code QM11:There are the list of notification when the notification numbers(second column) is checked with created on column, the notification numbers are not in sequence with creation date

Example:2XXXXX57 is created as on 05/05/2011,while the notification 2XXXXXX60 is created as on 18/04/2011.So the number range is not in sequence as with creation dateAs checked in the PRD system,

we have irregular notification numbers created with different creation dates

So following the checks made the possible reasons

recent Server changes(Production),checked for any recent client copy or the updates

found that we have recently moved transports as in May 2011,there are no TR related to QM doc ranges

Also when checked the Dumps in the PRD ,found dumps SAPSQL_ARRAY_INSERT_DUPREC,so we are currently workiing on this dump issue,as it may linked with document number range issue of quality notifications

Any other checks ,if missing please share your valuable inputs so as to recitfy the sameAlso there is a related note which is being refered
