Issue
Vertex O Series software is used by the current ECCs systems and will still be required for SyWay. The current solution runs on AWS as IasS but Vertex also delivers a on-demand SaaS version of the tool. This KDD aims at deciding which hosting solution would suit best SyWay. We also add a part remated to some etxra tools delivering a smoother implementation.
Recommendation
The recommendation goes for the Vertex On-Demand (i.e SaaS) solution. It will lower the internal workload without compromising on any features. Plus we recommend using the additional extra toolsets provided by Vertex in the form of the Vertex Plus Tools and the Vertex SAP Accelerator.
Both those tools will also simplify the integration between S/4 and Vertex and reduce the workload.
