    HDL Transformation & PeopleSoft → Oracle Fusion Field Mapping

    Turning staged PeopleSoft data into Oracle HCM Data Loader (HDL) files — code normalization, source-to-target field mapping, and business-rule transformation — the bridge between the legacy data model and Oracle Fusion.

    Staging & initial transformation

    Extracted data lands in the staging table PS_AZ_FILE_OC_STG for cleansing and standardization before HDL conversion:

    • Normalizing country and state codes
    • Aligning Business Unit codes
    • Mapping PeopleSoft department codes to Oracle Fusion structures
    • Applying business rules and eligibility filtering
    • Enriching records with derived information

    Field mapping: PeopleSoft → Oracle Fusion

    A source-to-target mapping matches each PeopleSoft field to its Oracle Fusion equivalent — meticulous work that is critical for statutory compliance and for consistency across systems. Examples include EMPLOYEE_ID → PERSON_NUMBER, name and department fields, and the Irish Revenue and PRSI fields that payroll reporting depends on.

    🇮🇪

    Irish Revenue fields

    Fields required for Irish Revenue reporting mapped explicitly so payroll data is compliant on day one.

    🛡️

    PRSI data

    Pay Related Social Insurance fields carried through mapping into the Fusion model.

    Automated HDL transformation

    Converting staged data into HDL format is automated, which brings an accelerated timeline (less manual effort) and error reduction (less human error). The output is a set of HDL files ready for the Oracle HCM Data Loader.

    Frequently asked questions

    What is HDL and why is it used?

    HDL is the Oracle HCM Data Loader — the supported bulk-load mechanism for Oracle Fusion HCM. Staged PeopleSoft data is transformed into HDL-compliant files that conform to Fusion specifications.

    How is PeopleSoft data mapped to Oracle Fusion?

    Through a source-to-target mapping document that matches each PeopleSoft field to its Fusion equivalent (e.g. EMPLOYEE_ID → PERSON_NUMBER), including the Irish Revenue and PRSI fields payroll needs.

    What transformation happens before HDL?

    Code normalization (country, state, business-unit and department codes), business-rule and eligibility filtering, and record enrichment in the staging table.
