Answer / goli

When a user logs on to the SAP R/3 System, a user buffer is
built containing all authorizations for that user. Each
user has their own individual user buffer. For example, if
user Smith logs on to the system, his user buffer contains
all authorizations of role USER_SMITH_ROLE. The user buffer
can be displayed in transaction SU56.

A user would fail an authorization check if:

* The authorization object does not exist in the user
buffer.
* The values checked by the application are not assigned to
the authorization object in the user buffer.
* The user buffer contains too many entries and has
overflowed. The number of entries in the user buffer can be
controlled using the system profile parameter
auth/number_in_userbuffer.
