SAP ECC and BambooHR integration

What moves between them

Employee data flows from BambooHR into SAP ECC. ml-connector polls BambooHR's employee list and compensation records on a schedule tied to your payroll cycle. For each active employee, it maps BambooHR employment status, job title, and assigned cost center into the SAP ECC employee master record (BAPI_EMPLOYEE_GETDATA) and verifies that the cost center exists in BAPI_COSTCENTER_GETLIST before writing. When an employee is terminated in BambooHR, ml-connector marks the employee record as inactive in SAP ECC. Compensation history (base salary, pay grade changes) flows into GL cost allocations so that labor cost journals post to the correct SAP general ledger accounts.

How ml-connector handles it

ml-connector stores the SAP RFC agent credentials (username, password, host, port) encrypted and uses Java Connector or .NET Connector calls to authenticate against the SAP instance per customer. For BambooHR, it manages the OAuth token lifecycle, requesting a refresh token via the per-customer OAuth endpoint (https://{companyDomain}.bamboohr.com/token.php) when the access token approaches expiry, and gracefully handles 401 responses by refreshing the token before retrying. Because SAP ECC is pull-only (no RFC webhooks), ml-connector polls BambooHR on a fixed schedule aligned with your payroll calendar (e.g., weekly, bi-weekly) and polls SAP cost centers and GL accounts to validate that every HR change maps to an existing GL dimension before posting. Write operations to SAP ECC require explicit BAPI_TRANSACTION_COMMIT calls; ml-connector ensures the commit succeeds before marking the record as synced. Employee ID mapping uses BambooHR's internal employee ID as the key to match against SAP ECC's employee number field, and any duplicate employee IDs are flagged in the audit log rather than silently overwriting.

A real-world example

A mid-market manufacturing company runs SAP ECC for production planning, cost accounting, and general ledger, and uses BambooHR for HR management across three plants and a corporate office. Before the integration, every time an employee was hired, transferred to a different cost center, or terminated, the HR team notified the accounting department, and the accounting staff manually updated the employee master record in SAP ECC and re-assigned the employee to the correct cost center. This manual process caused delays, duplicate records, and month-end reconciliation headaches when SAP headcount did not match the HR records. With BambooHR and SAP ECC connected, every hire, termination, and cost center change in BambooHR automatically flows into SAP ECC within hours, the cost center assignments are validated before they write, and the payroll GL accounts are reconciled correctly without manual intervention.

What you can do

• •Sync employee records, employment status changes, and cost center assignments from BambooHR into SAP ECC employee master records via BAPI calls.
• •Map BambooHR compensation history and pay grades into SAP ECC GL dimensions and cost center allocations so labor costs post to the correct accounts.
• •Validate cost centers and GL accounts in SAP ECC before writing HR changes, preventing orphaned records and GL posting errors.
• •Authenticate to SAP ECC via RFC Basic Auth with on-premises agent credentials and to BambooHR via OAuth 2.0 token refresh, handling expiry and temporary failures.
• •Poll BambooHR on a configurable schedule aligned with payroll cycles, with a full audit trail on every employee record change and BAPI transaction.

Questions

How does the integration authenticate to SAP ECC if SAP is on-premises?

ml-connector stores your SAP RFC agent credentials (username, password, host, port, client, language) encrypted. It uses SAP .NET Connector or Java Connector to make RFC/BAPI calls to your SAP ECC instance. The agent must run on a server with network access to SAP; ml-connector does not require an agent itself but relies on you to configure the connection parameters. BambooHR authentication is handled via OAuth 2.0 token refresh to your per-customer subdomain.

Does the integration support real-time employee changes or only scheduled polling?

The integration polls BambooHR on a schedule you define (e.g., every 4 hours or daily, aligned with your payroll cycle) because SAP ECC has no native webhook system for RFC callbacks. BambooHR does support webhooks for immediate notification, but SAP ECC is still pull-only, so changes must eventually be read via RFC polling. You can trigger a manual poll on demand if an urgent employee record change must sync immediately.

What happens if a BambooHR compensation change maps to a cost center that does not exist in SAP ECC?

ml-connector validates that the cost center exists in SAP ECC before writing the employee record. If the cost center is missing, ml-connector logs the error and does not post the record to SAP; the record is marked for manual review in the audit trail. This prevents orphaned GL allocations and gives your SAP Basis team time to add the missing cost center before the next sync attempt.
