Currently the only way to update the customer project forecast is to use the app "review customer project". My customer is using an external program (linked to non-SAP system as well) to feed S4 with plan and actual data. But for the forecast, they have to maintain manually because no interfacing is possibel.
I could not find any API to load forecast data which is really important to get a correct POC.
By any chance , any of you has already a such requirement? Do you know if SAP has foresee something on the roadmap about an API for forecast on customer porject?
tx in advance for your feedback
