Dear experts,

For past few weeks , client experience AX 2009 application slowness ,freezes and not allow to login to users in some intervals only . Post some analysis, it has been noticed that always SQL database had dead blocks as follows ,which is related to number sequence table.

SELECT TOP 1 A.NUMBERSEQUENCE, A.TXT, A.LATESTCLEANDATETIME, A.LATESTCLEANDATETIMETZID, A.LOWEST, A.HIGHEST, A.NEXTREC, A.BLOCKED, A.FORMAT, A.CONTINUOUS, A.CYCLIC, A.CLEANATACCESS, A.INUSE, A.NOINCREMENT, A.CLEANINTERVAL, A.DEL_LATESTCLEANDATE, A.DEL_LATESTCLEANTIME, A.ALLOWCHANGEUP, A.ALLOWCHANGEDOWN, A.MANUAL, A.FETCHAHEADQTY, A.FETCHAHEAD, A.MODIFIEDTRANSACTIONID, A.RECVERSION, A.RECID

FROM NUMBERSEQUENCETABLE A WITH ( UPDLOCK) WHERE ((DATAAREAID=@P1) AND (NUMBERSEQUENCE=@P2)) )

 In this blog , it quoted as Continuous number sequences might cause this issue and suggested to disable Continuous .

My question is that does MS published any guidelines/best practice which number sequence codes shouldn’t be continuous or share your project/client number sequence configuration experience and how you over come this issue ?

Thanks in advance.

    Last year there was a webinar and a conference talk on what users can do to optimize performance on the AXUG website.

    I would recommend that you check out those talks.

    Hi Sri17,

    Please take a look at link below:

    docs.microsoft.com/.../number-sequence-overview

    Haven't seen anything published from MS yet as it may be different for different countries. however most of the number sequence if can be made non-continuous should be non-continuous unless there is any specific requirement from customer (which at times may be on voucher number).

    Thanks,

    Hi sri17,

    I think the starting point is only allowing your finance guys using continuous number sequences where absolutely necessary.

    If this results in performance issues then there are a couple of things that you can use to pimp the performance.

    Last year there was a webinar and a conference talk on what users can do to optimize performance on the AXUG website.

    I would recommend that you check out those talks.

    Best regards,

    Ludwig

    Thanks Ludwig for the reply ,

    If that is the case , how to overcome the performance problem as stated by Tommy that any continuous number sequence can cause degraded performance if not used correctly.

    Any light ?

    Hello sri17,

    I have not seen such a detailed guideline that says number sequence for PO packing slips should not be set to continuous, for PO invoices it should be set to continuous, etc. etc.

    The general rule is only set only those number sequences to continuous where somebody (law, auditor, ...) forces you to do that.

    Best regards,

    Ludwig
