ROA Objects
ROA objects are data containers created by the processes. An object can
act as data input for subsequent processes. A single object can contain
several data values referred to as data items. These data items are the
values shown on the screens of the end-user applications.
The ROA objects can be monitored in the Diagnostics application. For
more information, see
Chapter 5, Diagnostics, on page 49
ROA objects can be divided into the following categories:
-
System objects
