Checking logged users' permissions by comparing their name to a hardcoded string can create security vulnerabilities. It prevents system
administrators from changing users' permissions when needed (example: when their account has been compromised). Thus system fields
SY-UNAME and SYST-UNAME should not be compared to hardcoded strings. Use instead AUTHORITY-CHECK to check
users' permissions.
This rule raises an issue when either of the system fields SY-UNAME or SYST-UNAME are compared to a hardcoded value in a
CASE statement or using one of the following operators: =, EQ, <>, NE.
