T1  - Development of an Interface for the Synchronization of Delivery Dates in an ERP Migration Phase
N2  - This paper focuses on designing a robust interface solution for synchronizing critical delivery dates during a complex ERP migration phase, necessitated by the parallel operation of a legacy system and a new target system. The core challenge is that automatic rollback operations triggered between the synchronized ERP systems—due to technical errors—are systematically not communicated to the downstream PPC systems (Production Planning and Control systems). This data inconsistency leads to significant business risks, including production disruptions, delivery delays, and increased inventory costs. The developed solution implements an API-centric approach based on Microservices principles to ensure loose coupling between the systems. It utilizes a two-stage synchronization mechanism to proactively resolve these inconsistencies. First, a time-delayed individual validation employs a strategic 30-minute buffer time to guarantee that potential ERP rollback operations are completed before consistency checks with the PPC system begin. Second, a comprehensive nightly consistency validation systematically reviews all business-relevant delivery dates within a defined time window and initiates automatic corrections. The system's status-based processing model, combined with comprehensive logging and a "Live-Feed" Web Interface, guarantees transaction security and complete traceability. This approach successfully minimizes business risks during the critical transition and offers an effective design pattern for handling rollback situations in similar complex, heterogeneous integration projects.
