Integrating with JDE/Concur

Summary:

Content (required):

Dear Experts, Has anyone implemented HCM extract directly with JDE and or Concur vendor applications without going through middleware? We are interfacing with these two vendors' application but were told years ago that it could not accept directly. We are looking to enhance this and see if we can make end to end direct instead of going through middleware. I would appreciate if anyone can provide thoughts/feedback if they have implemented this.
