When an employee’s payroll deductions don’t align with their benefit elections, it doesn’t just result in minor errors—it creates a ripple of risk:
SAP HCM is often the system of record for payroll. Vendors like Alight manage benefits enrollment. Without integration, these two systems drift apart—causing deduction mismatches and administrative chaos.
This is where point-to-point SAP integrations shine.

Payroll is the single most critical and risk-sensitive area in any SAP deployment. Integrating third-party systems into your payroll processes—without losing control of retroactivity, wage type generation, and deduction accuracy—requires a level of precision that only SAP-native point-to-point integrations can offer.
We dive into Infotype structures, ABAP interface designs, compliance considerations, and how to build integrations aligned with your payroll control record lifecycle.
At its core, point-to-point integration is the direct, tightly coupled connection between SAP and a third-party system, bypassing generic middleware tools. This method:
1. Reduces latency
2. Improves customization
3. Simplifies error handling
4. Aligns closely with payroll and compliance needs
Rather than sending data into a black box middleware, you're in full control—writing ABAP logic that knows exactly which Info type, PA subtype, or Wage Type to manipulate.
1. Data Extraction: Use ABAP programs or LSMW tools to pull employee master data, time punches, deduction records, etc. Accessed from Infotypes like 0002, 0167, 0378, 2010, 2011
2. Transformation: ABAP logic maps SAP internal formats to the vendor’s schema (e.g., Fidelity fixed-width layout, Alight’s ANSI X12)
3. File Generation & Encryption: Generated file stored on the SAP application server or NFS path PGP encryption applied if needed
4. Secure Transmission: Transferred via SFTP using command-line tools or SAP’s own connectivity add-ons
5. Audit Logging: All activity logged via custom Z-tables or application logs (SLG1)

2. TransformField Mapping Tables (V_T77SFEC_BIBF): Defines EC → Infotype field relationships
Transformation Templates: Handle conversion logic (e.g., map EC ‘grade’ to SAP ‘job group’)
Filters: Set by country, employment type, event reason
Switches: To allow client-specific logic branching ation: ABAP logic maps SAP internal formats to the vendor’s schema (e.g., Fidelity fixed-width layout, Alight’s ANSI X12)

If a benefit enrollment change occurs after the payroll cutoff, SAP must:
This is done by:
ABAP logic enforces:
Issue:
Employees enrolling in Health Savings Account (HSA) after the cutoff faced missed deductions and had to wait for refunds.
Solution
Result:

Health data must be encrypted in transmission

Deduction limits for HSA/FSA must be enforced

Coverage effective dates must match employer mandate thresholds
