Denis made a good point about choosing the path of integration based on the specific requirements of the scheduling software and the ERP. However, it's important to highlight that this line of reasoning often leads to the existence of those many point-to-point connections, which can complicate the IT landscape over time. The decision should be based of not only your current needs but also future integration requirements. While integrating the scheduling software directly with the ERP seems straightforward now, consider whether other systems, like a MES, might need to access this data in the future. Without detailed knowledge of your systems, it's challenging to provide a specific recommendation. In the end, it's crucial to weigh the immediate convenience against potential future needs. So in short: depends on what the scheduling software does
