SAP SCM architecture for the problems without a template
I'm Omar Olwan — a master of SAP Materials Management and supply chain, at home in the cross-functional ground where MM meets AP, FI, and PM. I lead design authority on multi-country programs, and I'm still the one who writes the functional specs, the code, and knows the tables cold. Master data, code, configuration — I go as deep as the problem requires, and I've delivered one complex SAP program after another.

Five things that don't change from program to program
Deep, not generalist
SAP MM, MRP, procure-to-pay and source-to-pay — including the master data work most architects delegate: legacy-to-SAP mapping, load templates, and mapping matrices built for migration teams to actually execute against.
Cross-platform & integration
I'm usually brought in once a template has stopped working. I rebuild it into the enterprise standard — not just patch what's already there
Built for real operations
Designed for cutover, UAT, hypercare, and end-user adoption — the phase where most procurement programs actually break.
MM + PM, a rare
