Provision User via IPS to SAP Concur via Identity v4 API

[LX_]

Dear Community,

I hope my question finds you well!

Does anyone have experience with provisioning users from SAP Cloud Identity Services – Identity Directory via SAP IPS using the latest API version, Identity v4 API (also known as IPS property concur.api.version = 2)?

We were able to provision users with their core identity information (part of the main identity), but are not able to maintain attributes that are part of Spend or Travel. Based on what we found in this documentation:
https://developer.concur.com/api-reference/user-provisioning/v4.user-provisioning.html

…it seems that you need to call the UPS (User Provisioning Service) in order to maintain all attributes. This URL should follow the pattern:

https://{datacenterURI}/profile/v4/Users/

What SAP IPS does instead is call the following URL:

https://{datacenterURI}/profile/identity/v4/Users/

Does anyone know if there is a way to determine which URL is used by SAP IPS? It seems that the property concur.api.version defines which API URL is being used.

EDIT:

As described here, it seems that SAP IPS is restricted from maintaining the Spend Profile.

However, we think that it might be possible to achieve this using the IPS target system type "SCIM-System" to reach the following API URL:

https://{datacenterURI}/profile/v4/Users/

Any feedback from someone who has tried this before or has any further information about integrating SAP IPS would be much appreciated 🙂

Thank you in advance for your feedback and kind regards,
Alex
