The migration of an enterprise SAP system from one major version to another is a project that consumes years of preparation and, traditionally, a long blackout period during which production transactions cannot flow. Holcim Services South Asia, the shared services arm of the Swiss building materials group, faced one such project in the late 2000s: a planned move from SAP 4.6C to ECC 6.0 across multiple group companies on the subcontinent. The technical lead on the upgrade was Heta Amritlal Patel, an ABAP developer who had joined the organization in April 2007.

Patel's contribution to the project was a proprietary suite of automation tools that took the most labor-intensive parts of the conversion - the SPDD and SPAU adjustment cycles, the remediation of hundreds of customer modifications, and the validation of dependent transports - and codified them as repeatable scripts. The result, recorded in Patel's biographical materials, was a reduction in system downtime from twenty-four hours to three. An 87.5 percent compression of the upgrade window in a project of this scale is the kind of outcome that ordinarily generates a case study; it is also the kind of outcome that tends to attract the next assignment.
