How to identify shadow enabled customer transport ord

Based on a white list approach the transport orders are checked :

Objects with object type listed in the white list are moved to shadow instance White list currently contains about 100 entries of objects types

Examples for shadow enabled objects

– Dictionary objects (e.g. tables, view types, search help),

– ABAP objects (e.g. classes, programs, screens)

Examples for objects transported in downtime

– Roles,

– Authority objects,

– Forms,

– Customizing Uptime
