Function documentationSelecting the Display Mode for Displaying Statistics Records

 

If you want to display ABAP Statistics Records for performance analysis, you can use transaction STADWD for this purpose. In this transaction you define, among other things, the criteria in accordance with which the displayed main statistics records and formatted and sorted. You have the following options:

  • Sort by time

    The main records are sorted by the time at which the action starts.

  • Sort by trans IDs

    A new trans ID (transaction ID) is always assigned when a user starts a transaction. While the user is using this transaction, this trans ID remains constant for all of his or her actions within the transaction, until the user ends the transaction again. If you select this option, it means that the main records are no longer sorted by time, but rather you can find all of the actions that a user performs while using a transaction, among other things. Actions with different trans IDs are sorted by the time at which the transaction is started.

  • Aggregate by trans IDs

    This display mode is largely the same as the mode described above, Sort by Trans IDs, but the actions with the same trans IDs are also hierarchically sorted in accordance with the following hierarchy:

    All actions with the same trans ID

         All actions on the same instance with the same task type

              Individual actions

  • EPP filter

    EPP stands for "Extended Passport“. There is a corresponding subrecord that contains, among other things, information about the user who originally triggered an action (even across system boundaries). Two IDs with the following properties are generated:

    • The Root Context ID is generated for each new action. If additional steps (for example, over RFC) are performed due to this action, this ID remains constant, so that you can identify the original action (even across system boundaries).

    • The Connection ID is always generated if a calls to a particular RFC destination are made within an action. As long as the RFC destination remains open within this action, the Connection ID remains constant for additional RFC calls using this connection.

    If you choose the EPP filter display mode, you can enter in the EPP Filter Options the Root Context ID or the Connection ID by which you want to filter the statistics records to be displayed. This display mode is usually used for the second step of an investigation. For example, if you have discovered a statistics record for which you are interested in the associated actions in other systems or instances. If you want to display the Extended Passport subrecord for this record (more information: Displaying the Statistics Records), you can determine the relevant Root Context ID, and specify it in the EPP Filter in a second step.
