Background

The HCM Conversion Workbench is an approach and a toolkit that has evolved through multiple SAP HCM conversions from a variety of legacy systems for both new implementations and acquisitions.

The primary goal of the workbench is to retain the benefits of a programmed, automated conversion process and still minimize coding effort by reusing common program logic and leveraging data mapping and translation spreadsheets.

Step 1 – Legacy Data Extract

The legacy data is extracted from the source system in whatever format is the easiest and quickest to generate, in its “raw” untranslated form.

This minimizes the dependency on legacy resources and allows for fast and frequent extracts.

Step 2 – Data Transformation

The data transformation from legacy to SAP is completely automated in ABAP programs that are configurable with data mapping and translation spreadsheets.

The inputs are the legacy data files; the outputs are the infotype load files.

Step 3 – Data Load

A generic infotype load utility reads the load files created by the translator and loads the master data infotypes via BDC sessions.

This utility uses the same loader templates as the Best Practices Loader/DTT.

The main screen is the launchpad for all of the functions built in to the Workbench, including:• Translators • Loaders• Utilities

The Translators read the legacy data extract files and create the infotype load files.

One Infotype Loader program supports all the OM and PA infotypes.

This takes the place of the Best Practices Data Transfer Toolkit or LSMW as a loading mechanism

The HR Consistency Check Report provides a quick way to validate the conversion.

It can check for missing infotypes or any other data inconsistencies which may cause problems in downstream processing (payroll, interfaces, etc).
