Web Services REST to create Forecast Line in Financial Summary and to update Forecast and Actauls cells are availabe and documented?

Hi All.

I need to integrate the Financial Summary from external system. The capabilities required are:

- create a Forecast Line

- update Forecast cell

- update Actuals cell

I would like to use REST Web Services, but in my understanding such capabilities are not supported (by <PPM_BASE_URL>/itg/rest2/swagger.json

I retrieved the related old discussion https://community.microfocus.com/devops-cloud/proj-port-mgmt/f/discussions/516659/any-webservice-soap-or-rest-available-for-financial-summary-actuals-update-in-ppm-9-62 

My question are:

  1. do I wrong the investigation, the required capabilities are available and documented ?
  2. if NOT, the recommedation contained in the related old discussion are still valid ?

Best Regards, Silvio
