Approval Workflow (for object type BUS2094)

["Jäger, Sascha"]

Dear workflowers,
 
we want to define an Approval Workflow (for object type BUS2094) within a 4.5b System.
In dependency of an amount (in Euro) different persons have to approve the Workflow. We'll have PD-Org from a HR System.
I've already tried a standard role with responsibilities. This works fine for a single-level approval, but we have a multi-level approval signature directive like the following:
 
1-5000 Euro             -> head of department
5001-25000 Euro -> area manager
>25000 Euro             -> area manager + business manager
 
Does anyone knows, if there is a standard solution (no Z table with bespoken reports!) which meets this requirements?
 
(I didn't found anything about this whether in the documentation nor in the OSS System.)
 
Any idea or hint will be appreciated.
 
Thanks and Kind regards,
Sascha
