Integration Process Flow

​
Data Flow

  • The SAP BTP Skill Sync brokers all communication between TechWolf and SAP SuccessFactors through three Integration Flows deployed in the customer’s SAP Integration Suite. Every request passes through a customer-owned iFlow, so TechWolf never calls SuccessFactors APIs directly.
  • The iFlows authenticate to SuccessFactors using an OAuth 2 SAML Bearer Assertion, backed by a customer-managed X.509 certificate stored in the BTP Keystore. TechWolf authenticates to the iFlows using OAuth 2 Client Credentials, backed by the Process Integration Runtime service key created during installation (Employees / Jobs ).
  • Employee and Job Skills are synchronized in a bidirectional flow, where Employee and Job Skill data updates in the TechWolf SkillEngine API are synchronized in real-time to SAP SuccessFactors using the iFlows, following a push strategy.
    • TechWolf-originated Employee Skill Profile updates are pushed to SAP SuccessFactors Growth Portfolios using the Update Employee Growth Portfolio Integration Flow.
    • TechWolf-originated Job Skill Profile updates are pushed to SAP SuccessFactors Job Role Skill Mappings using the Update RoleSkillMappingEntity Integration Flow.
  • SAP SuccessFactors updates to Job Skill Profiles are synced at regular intervals to the SkillEngine API using a TechWolf-initiated pull strategy.
    • The frequency by which SAP SuccessFactors Skills are synchronized to TechWolf is configurable, but bi-hourly by default.
    • TechWolf pulls the current state of the Job Role Skill Mappings from SAP SuccessFactors using the Query RoleSkillMappingEntity Integration Flow.
    • Job Skills synced by the SAP BTP Skill Sync are tracked using the source field in the Job Skill Profile Feedback endpoint payload, tagged as "sap-integration". To retrieve these sources from a Job, use the List Job Profile Data endpoint . Items with "data_type": "skill_profile_feedback" and "source": "sap-integration" indicate Skills synced by the SAP BTP Skill Sync.
  • Employee Skills synced by the SAP BTP Skill Sync are tracked using the source field in the Employee Skill Profile Feedback endpoint payload, tagged as "sap-integration". To retrieve these sources in an Employee’s profile, use the query parameter ?include=sources in the Employee Skill Profile Feedback endpoint , which returns the Skill’s source_event with "event_type": "skill_profile_feedback" and "source": "sap-integration".
  • Every iFlow-brokered call carries the TechWolf AIR key in its request header so SAP SuccessFactors can attribute traffic to the TechWolf Skill Sync partner solution.
In summary: TechWolf uses the three iFlows in your SAP Integration Suite as the single integration surface to SuccessFactors. Job Skill Profiles sync bidirectionally (real-time push from TechWolf, bi-hourly pull into TechWolf). Employee Skill Profiles sync in near-real time from TechWolf to SuccessFactors via the Talent Intelligence Hub REST API. The latest state of the Employee Growth Portfolios is also propagated to TechWolf through a file-based sync. All file-based integrations are managed through the SAP Integration Center.

Configuration Options

​
Sync Direction

The integration supports three sync direction options, specifying which data flow directions are allowed:
  1. TechWolf - SAP Bidirectional Sync (default): Two-way sync between TechWolf and SAP SuccessFactors; changes made in TechWolf Skill Profiles are synchronized to their corresponding SAP SuccessFactors Skill Profiles, and vice versa.
  2. TechWolf to SAP Unidirectional Sync: Skills flow from TechWolf to SAP SuccessFactors only; changes made in TechWolf Skill Profiles are copied to their corresponding SAP SuccessFactors Skill Profiles, while changes made in SAP SuccessFactors are discarded and overwritten with the state of the TechWolf Skill Profiles.
  3. SAP to TechWolf Unidirectional Sync: Skills flow from SAP SuccessFactors to TechWolf only; changes made in SAP SuccessFactors Skill Profiles are copied to their corresponding TechWolf Skill Profiles, while changes made in TechWolf are discarded and overwritten with the state of the SAP SuccessFactors Skill Profiles.

​
Initial Load Merge Strategy

For the correct functioning of the normal operation of the integration, the Skill Profiles in both systems should be initially aligned. The integration will do this initial alignment itself automatically when the integration is first enabled, or when it is re-enabled after having been paused, or when it encounters an entity it had no knowledge about yet. The initial alignment can happen in different ways; we support three such merge strategy options:
  1. Merge Systems: Combines Skills from both SAP SuccessFactors and TechWolf systems. Skills present in SAP SuccessFactors but not in TechWolf will be synced to TechWolf, and vice versa. This preserves existing Skill data in both systems. TechWolf takes precedence over SAP SuccessFactors in case of conflicting values (e.g. conflicting proficiency levels).
  2. Push TechWolf: Replaces all Skills in SAP SuccessFactors with the Skill data from TechWolf. This strategy clears existing SAP SuccessFactors Skills before importing TechWolf data.
  3. Push SAP: Replaces all Skills in TechWolf with the Skill data from SAP SuccessFactors. This strategy clears existing TechWolf Skills before importing SAP SuccessFactors data.
