the IFRS 16 solution accelerator is sold through IBM business partners on a fixed price statement of work and gives client a quick start for IFRS 16. Typically there is a start up/configuration service provided. If you want I can connect you with a local IBM representative to help you out.
It's recommended to use Planning Analytics SaaS with digital pack or base or the on-premise version of Planning Analytics. However the solution accelerator comes with a number of created web sheets why Planning Analytics on Demand isn't the recommended approach.Hope it helps!
