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 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.
