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.

For Work area check this link...

hi

user context contains user authorization like your user name,your authorization for a particular transaction etc.

Jus go thru the below scenario.

Once you start executing any transaction/program say for eg you are executing VA01 transaction for sales order creation now the request will go from your presentation server to the application server.Now the user context will be rolled into the application server's roll area.

Roll area is nothing but a temporary buffer in your applciation server.If you have valid authorization then the application server will allow you to process whatever you want else you will get an error message something like 'You are not authorized to execute the transaction'.

Still confused then let me know...

Cheers,

Abdul Hakim

Hi,

<b> Roll Area</b>

This parameter is used to specify the total size of the roll area, in bytes.

<b>Activities</b>

The roll area is not important with 64 bit platforms where sufficient extended memory is available. The default value is platform-specific and is determined dynamically. The default value is specified in transaction RZ11. This value should not normally be changed.

<b>User Contexts</b>

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.
