A Readiness Checklist for ERP or S/4HANA Integration with Decentralized EWM

Overview

Integration guides can feel long because they are long. A readiness checklist helps translate that detail into a project conversation people can act on.

Core prerequisites

Confirm that the enterprise system and decentralized EWM releases fit the intended scenario, that required applications are active, that the EWM client has the necessary warehouse-independent configuration content, and that mandatory SAP notes have been reviewed.

Communication design

Review logical systems, RFC destinations, qRFC setup, ALE or DRF decisions, reduced message types, partner profiles, and change-pointer strategy. If communication setup is unclear, do not rush into process testing.

Warehouse integration

Check enterprise structure assignments, supply chain unit creation, warehouse creation and integration in EWM, number ranges, HU numbering, and additional transfer settings for transaction data and batches.

Support readiness

Ask who monitors queues, IDocs, master-data failures, and warehouse integration issues after go-live. A project is only ready when the support model is visible.

Quick takeaways

• A readiness checklist converts a long guide into a manageable governance tool.
• Communication setup and warehouse integration should be reviewed together.
• Go-live readiness includes support ownership, not only configuration completion.
