If you have created structural authorizations with a large number of objects, it is advisable for performance tuning reasons to generate indices for users assigned to these structural authorizations. You can do this using the RHBAUS00 report.
Before you can run this report, you should have specified in table T77UU (User Data in SAP Memory) which users' structural authorization data should be permanently stored in the SAP memory and how often the data should be refreshed (Days field).
There are two possible ways to fill the index with data:
The index can be filled automatically at fixed intervals. In this case, you have to ensure that the user's view is up-to-date on a daily basis because data is refreshed after a batch input session that runs at night.
The index can be filled manually by means of the report. This report updates the data in the SAP memory immediately.
Once the report has been run, you obtain a log that contains a list of the users whose index was regenerated and the number of objects that were included in the index for a user.
Indexes for Structural Authorization Profiles (2)
You can use the RHBAUS01 report to compare the INDX and T77UU tables (Save User Data in SAP Memory). This report generates a list of users who have structural authorization data in the SAP memory, but who are no longer entered in table T77UU. The report also enables you to delete the entries of the users no longer in the T77UU table from the INDX table.
You can use the RHBAUS02 report to enter users that have authorization for a large number of objects in table T77UU (User Data in SAP Memory) or to delete users with a small number of objects from this table.
This report enters users in the T77UU table or deletes users from this table if they have too small a number of objects depending on a threshold value. You can define the threshold value for the report (for example, 1000 for 1000 objects).
The report can then automatically perform the Customizing activity Save User Data in SAP Memory.
