WF for travel managment

["Schröder, Ute Marion"]

Hi all,
 
our company evaluates the possibilities to run workflow for travel
managment,
there are different solutions to discuss, one of them is SAP.
Thia seems to be preferable due to data being already in the system.
 
Today, my superior asked me, how the user managment has to be done.
As far as I know, every user who works with SAP needs his own userid.
In our case the user should type his travel data directly into the system
via an
Website.
The question is how userids have to be organized, is there a possibility to
to reduce the needed ids?
 
Helps highly appreciated 'cause I'm a bit at a loss.
 
thanx
 
Ute
