Implementing SAP Workflow without using Org Structure

[Cristiana D'Agosto]

Hello workflow experts,
 
I believe that it is possible to implement SAP Workflow without having to
implement the SAP HR PD Org Structure. Probably using customized tables to
store the info needed (eg. who reports to who, etc).
 
>From your experience, there is any advantages in using customized tables
as opposed to using the HR PD Org Structure?
 
It seems to me that the approach of customized tables would limit the
options of retrieving data for future workflows if the rules that define
an approver changes?
 
Any thoughts on this subject will be more than welcome!
 
Thanks and regards
 
Cristiana
