Hello,
We have implemented HR Renewal previously with an Embedded Gateway and everything went okay (few notes here and there but generally ok 
On our current project, we are using a Gateway HUB (External Gateway) and a Web Dispatcher and we are slowly working our way through the challenges.
The main issue right now is the missing CHIPs in the SBP admin page, we are only seeing 15 CHIPs. The HR Renewal CHIPs are missing (see screenshot). All required OData and SICF are active.
Any idea on this issue? Appreciate your help. Thanks!
