!Connecting SAP SuccessFactors Using an OAuth 2.0 Client (OA2CS)

Follow \\
SIMG > ABAP Platform > Application Server > Basis Services > Communication Interfaces \\
> OAuth 2.0 Client Implementation for SAP SuccessFactors Integration

The default implementation allows only a connection to ONE SuccessFactors instance.\\
Then you can use the existing objects.

This ones decribes how to create custom objects for multiple instances.

!certificates / communication
1. Configure Proxy Settings\\
x.SICF > F8 > Menu > Client > Proxy Settings \\
*   > HTTPS Protocol = <host>:<port> SKIPPED !!!\\
*   > Global Settings > Set Active SKIPPED !!!
   

!OAuth configuration
* OAuth profile, default "SUCCESSFACTORS", use SE80 > Create > Others > OAuth 2.0 Client Profile (t.OA2C_PROFILES)
* Application ID, default "DEFAULT", x.CLB2_APPLI
* Provider type, default "SuccessFactors", x.CLB2_PTYPE (SM30 > CLB2V_PTYPE)
* Application Server Assignment, default "DEFAULT", SM34 > CLB2VC_APPLI_PLATF  <= here we have the OAuth App ID and the companyId
* Server Communication, default "SuccessFactors", SM34 > CLB2VC_PLATF (SM30 > CLB2V_PLATF), make sure to fill also the "Authentication Methods" like USER
* Server, default "SuccessFactors", SM34 > CLB2VC_PLATF_DEF 
* Application Settings" for each instance with SM30 > CLB2V_APPL_DATA
* Parameters for each instance with SM30 > CLB2V_APPL_EXT, here we have company_id

!Modifications
Whenever you choose to create SAML a new STRUST is created:
"SSF OAuth2 Client Identity Provider - Signature" (x.SSFA)
table SSFAPPLIC  <====
	> Create entry with r.ZMDW_TEST


Note: use always same case to avoid mixing up at all artifacts:
Profile, Type, Application ID, Service Provider Type, SSF ID, Server
