[former_member135351]

This blog is focused on providing a detailed process on two-tier ERP solution for project-based engineer-to-order with headquarters and subsidiary.

Most manufacturing companies spread their production across the globe. In this process, they struggle to maximize their operational efficiency when it comes to cost, time, and quality. It is mainly due to the lack of transparency during various stages of production.

The two-tier ERP model helps companies bring the organization together, spread across the globe. The companies can keep their existing first tier as ERP system at the headquarters and SAP S/4 HANA Cloud system as second tier at various subsidiaries/business units. The project-based manufacturing setup across the two-tier will help companies in organizing well the various production-related task allocated to different subsidiaries.
