Workflow substitutes in a multi SAP system component lanscape

[jerry martinek]

Hi All,

I need some help trying to understand and figure out how to best proceed with a recommendation/solution for defining workflow substitutes in a new SAP installation that includes the following components: Netweaver 2004S, EP6,  SRM5 and ERP 2005.

The client is planning to rollout various ESS, MSS, ERP and SRM workflows throughout the organization and use the UWL for all workflow scenarios.
 
Being new to the portal and UWL, I been reading and trying different things with respect to maintaining substitutes in the ERP and SRM systems as well as the UWL. 

I’ve figured out that the UWL substitute processing is not linked to the ERP and SRM functionality. This means that anyone responsible for approvals will need to log into the ERP system and define the required personal substitutes in the Workflow Inbox and then repeat the same process in the SRM Approval tab.

If the above is the only way to define substitutes, then the process will not be met with open arms for all sorts of reasons. 

As I’m new to these new SAP components, am I missing something? There is a simple solution to defining substitutes in this type of a system landscape or do you need to build something to provide the required/desired single entry point for both systems.

Also, what do the UWL substitutes provide?

Regards,
Jerry
