Workflow error queue - organize by vendor

Question

We use workflow to house EDI Idoc errors.  Currently, WE20 is set up in the Post Processing: Partner type LI (Vendor), permitted agent tab with Type 'O' and an Agent group. 
We would eventually like for one person to be able to work one type of document for a vendor.  To avoid coding changes, we are now testing with setting WE20 Type to User and the Agent to a specific user.
Is anyone set up like this?  What do you do when someone is out on vacation or leaves the company?  Even when I reassigned the vendor to a different user, the errors visible to the original user for that vendor are not re-assigned to the new permitted agent.  It is only errors go forward.
Looking for suggestions on how to handle the exception flow.

Answer 1

There are two parts to your question:
1- Substitution when someone leaves on company or goes on vacation. Typically, users can assign their own substitutes using SAP Inbox (transaction SBWP) menu option: Settings->Workflow Settings->Activate/Deactivate Substitute. If they leave without setting a substitute, workflow administrator should be able to assign substitutes using transaction RMPS_SET_SUBSTITUTE.
2- Assign different agents for each vendor: You can use "rules" (transaction PFAC). In this transaction you can assign a field (vendor) and you will need to define the data element of that field. Then, for this field, you assign responsibilities (range of vendors). So, for example, responsibility R1 is for vendors from 1 - 100 and R2 is for vendors from 2 - 200, and so on. You can even assign a single vendor to each responsibility. In your workflow, you assign this rule as the agent and in the binding  you link the vendor field in the workflow to the vendor field in the rule. Then, in QA, production, or any system, you need to use transaction OOCU_RESP to assign actual agents to the different responsibilities. Agents can be Org Units (type O), persons (type P), positions (type S), Jobs (type C), or user (type US).
