Dear Experts,

After some time those are going, but here when i am checking Addition Data--> Threads those are fully utilized 15/15.

We maintained Thread count is 250 and We are assigned worker threads for asyn and sync 15,15,12,12.

Kiran Polani

    • Dear all,

      Thanks for your support, i found this error in SAP Idoc level and those are checked with processing inorder check box in SAP side. that's why Queues are going slowly one by one.

      After unchecking that check box queues are going smoothly and increased worker threads for fastning Queues and given priority for that interface as per SAP Labs Suggestion.

      Hello Kiran,

      Kindly check the below notes and you would have to use Poolwaiting time parameter.

      Note 937159 – To be used for the stating our point of failure and increasing ThreadCount.

      Note 821267 and 1473299– To be used for suggesting poolWaitingtime parameter.

      This should fix your problem.

      Regards,

      Hiren

    Hi Kiran,

    Message ToBeDeliver means that the message is sitting in the queue waiting to be processed.

    In most situations, when this happens and stays there for a long time is because 1st message is the queue is being held up by an error.

    BTW, what is your scenario ? what is your receiver system ?

    Thanks

    Hari.

    Dear Harish,

    We unchecked in we20 "Queue Processing" in sap R/3 end for Idoc and unchecked in "Maintain Order at Runtime" in inteface Determination in XI level for avoiding EOIO format. Now those are going EO only with in XBT* Queues. But some times queues are going slowly and at a time in smq2 2000 messages are coming to XI end from R/3 Server, those signals going with 4, 5mins, but why suddently singals are coming to XI End & in Engine status Backlogs also we are able to see 1000 queues those are going but taking some time.
