SAP Note 20128 - User name - ? - in tran. ST03, top 40 hit lists .

Symptom

In transactions ST03, ST03N, ST03G, STAD, or STATTRACE, no user names are displayed. Instead, the system displays "- ? -" or a hash key (as of SAP_BASIS 7.00).
This also affects the BI-based IT performance reporting in Solution Manager.

Reason and Prerequisites

The user is not authorized to display user data.

Solution
The user requires the value S_TOOLS_EX_A in the field AUTH of authorization object S_TOOLS_EX. This exists, for example, in the profile S_TOOLS_EX.
For the BI-based IT performance reporting, the user that you use for the data extraction must have the relevant authorization.
