Determine Permissions Error by Debugging
Permissions checks
You assign a reference user to a dialogue user by registering the reference user for additional rights in the SU01 transaction on the Roles tab in the Reference User field. If you are using Central User Administration (ZBV), the assignment applies to all connected systems. If the reference user does not exist in one of the systems, the mapping is ignored. However, the use of reference users also creates risks. This makes it easier to summarise permissions because it is difficult to keep track of the assigned permissions. In SAP NetWeaver AS ABAP 7.0 and above, reference users are considered in the reports of the user information system.
Increased compliance requirements and the design of internal control systems confront companies with an increasing number of rules on how SAP (and other IT) systems must be technically protected. The SAP authorization concept specifies such legal standards and internal company rules. This ensures that each user only receives the authorizations he or she needs for his or her activities. The business risk can thus be reduced to a minimum.
WHY ACCESS CONTROL
Alternatively, you can maintain this information from the SE93 transaction by selecting a transaction first. You will then be presented with the list of all transactions that can be called from this transaction by using the Tools > Called Transaction Permission menu path. The implementation of SAP Note 1870622 provides a feature enhancement for the SE97 transaction. Among other things, there is the new button Modification Synchronisation. So far, changes in the SE97 transaction have been overwritten by inserting support packages or upgrades. With the modification comparison it is now possible to match your changes with the default values.
SAP authorizations control the access options of users in an SAP system, for example to personal data. Managing this access securely is essential for every company. This makes authorization concepts, authorization tools and automated protection of the SAP system all the more important.
Secure your go-live additionally with "Shortcut for SAP systems". You can assign necessary SAP authorizations quickly and easily directly in the system.
Here you can check whether there are parameter or variant transactions for a given table, or for a particular view, for which you can set up permissions, instead of allowing access to the table through generic table access tools.
This applies to the USR02 and USH02 tables and in more recent releases the USRPWDHISTORY table.
