SAP E-Book


You can use this program in cases where performance bottlenecks occur during the processing of CIF queue entries (LUWs) by the scheduler for outbound queues (QOUT scheduler). Performance bottlenecks can occur, for example, if a large number of CIF queue entries have built up in the outbound queue as a result of system downtimes or other technical problems in the system.

Note that the program is intended for emergency situations only. Do not use the program as a standard substitute for the QOUT scheduler. For this reason, make sure that you reset the settings changed temporarily in transaction SMQS to the original values once the program has ended.





The selection screen contains the following fields:

  • Recipient
Here you enter the name of the recipient who is to be notified automatically when the program has ended.
  • Recipient Type
A recipient type can be the user name or an Internet address, for example.

Standard Variants


The system sends a notification to the recipient when the program has ended.


  1. You call the QOUT scheduler using transaction SMQS. You deregister the existing destination entries and register new entries with the prefix ZZ.
    For the CIF destinations, this means that you e.g. delete the entry CF* and create a new entry ZZCF*. As a result, the QOUT scheduler ignores the CIF destinations and they can be processed by the program /SAPAPO/CIF_EMRG_QOUTSCHED.
  2. You start the program /SAPAPO/CIF_EMRG_QOUTSCHED. To avoid performance problems and timeouts during the execution of the program, you can execute the program in the background only. During the runtime, the program writes additional information about the queues that have been started to the spool. The program comes to an end after a defined number of internal runs.
  3. After the program has come to an end, the recipient specified in the selection screen is notified automatically.
  4. If, after the program has run, there is still a large number of CIF queue entries in the oubound queue, start the program again.
  5. After the program has ended, you reset the settings that we changed temporarily in transaction SMQS to the original values. Notifying the recipient ensures that the settings are reset shortly after the program has ended.
