hi,
Dialog Work Process
Dialog work processes deal with requests from an active user to execute dialog steps (see also Dialog Programming).
Update Work Process
Update work processes execute database update requests. Update requests are part of an SAP LUW that bundle the database operations resulting from the dialog in a database LUW for processing in the background.
Background Work Process
Background work processes process programs that can be executed without user interaction (background jobs).
Enqueue Work Process
The enqueue work process administers a lock table in the shared memory area. The lock table contains the logical database locks for NetWeaver AS ABAP and is an important part of the SAP LUW concept. In NW AS, you may only have one lock table. You may therefore also only have one ABAP application server with enqueue work processes. Normally, a single enqueue work process is sufficient to perform the required tasks.
Spool Work Process
The spool work process passes sequential datasets to a printer or to optical archiving. Each ABAP application server may contain only one spool work process.
