Roll Area:

Each Internal Session is subdivided into PXA

and Roll Area. The PXA (Program Execution Area) is

a shared memory for the byte codes of all

programs running concurrently at any one time on

an application server. Only the Roll Area is the

memory that is actually reserved for the data and

objects of each individual internal session.

Work Area:

The object types that you want to display

and process in the Engineering Workbench are called

as Work Areas. Work Areas have been created

in Customizing for the Engineering Workbench by

your system administrator.

User Contexts

The memory management system assigns memory to user contexts from the following areas: roll area, SAP extended memory, and heap memory.

The order of assignment from these memory areas arranges itself according to whether the user context runs in an SAP dialog work process or in another SAP work process. This enables the SAP system to optimally use the characteristics of the individual memory types.

When allocating memory, the following characteristics for individual memory types become noticeable.
