What is mean by SAP Process Flow?

SAP runs eight different types of processes on Application Server. How many actual processes would be run for each type is dictated by SAP instance profiles (which we will talk about next).

These SAP process are sometimes references as DVEBMSG, where

D – dial work process

V – update work processes

V1 – high priority update

V2 – low priority update

E – enqueue

B – background/batch jobs

M – message service

S – spooling (print)

G – gateway

System Administrator can monitor these processes through SAP’s front end interface.

SAP is a tool allowing SAP process flow from start to finish from one department to the other without losing anything and without paper (which is also a good thing for the 5S policies most companies have). But more seriously, SAP is a user friendly tool to allow everything to process correctly from the front office to the back office.

Let me give you an example to clear up a little this explication:

SAP Process Flow

DVEBMSG Descriptions         

Process Name: Dialog

Letter: D

Description: Process real-time information in the foreground

Process Name: Background

Letter: D

Description: Background processing for long-running processes, reports, and batch jobs.

Process Name: Synchronous Update

Description: Processes immediate updates to the database

Letter: V2

Description: Processes updates to the database on a lower priority than V1; on time-permits basis.

Process Name: Enqueue

Letter: E

Description: Manages database locks.

Process Name: Message

Letter: M

Description: Manages communication between application servers.

Process Name: Spool

Letter: S

Description: Manages print jobs (the print spool).

Process Name: Gateway

Letter: G

Description: Communicates with other SAP and non-SAP systems.

SAP Profiles

SAP Profiles are text files containing configuration information.

There are three SAP Profiles:

Default Profile

Start Profile

Instance Profile

An SAP System may consists of more than one SAP instance for the purpose of load balancing.

Default Profile contains information common to all SAP instances within an SAP system.

Start profile contains the executable commands for starting SAP processes.

Instance profile contains information specific to an instance.

There would be one Instance profile for each SAP instance.

It would contain configuration information like:

Memory configuration

Buffer sizes

Number of Work Processes

System Administrator can manage SAP Profiles through front-end interface.
