Oracle Workflow vs BPEL (@EBS)

Workflow is an essential and tightly-integrated part of the E-Business Suite, and as per Oracle they don't have any plans to replace workflow in EBS with BPEL.

Workflow and BPEL complement each other in environments that include EBS and other systems. 

• Workflow is used within EBS for process orchestration between EBS products (e.g. between EBS Financials and EBS Procurement).

• BPEL is used for process orchestration between EBS and other systems (e.g. between EBS Financials and PeopleSoft).
