Just a quick post to highlight a feature in Project Online when changing the rollup of timephased reporting data in Project Online as posted here:
As per the Microsoft support article below:
This mentions only the following endpoints in relation to this change:
You will also find that the ResourceDemandTimephasedDataSet endpoint is also impacted by this reporting setting if your projects are set to calculate the resource utilisation from the Project Plan / Project Plan Until. For example, if you have the timephased data setting set to Never as seen below and your projects resource utilisation is set to the Project Plan, the resource demand for those projects will not appear in the ResourceDemandTimephasedDataSet endpoint.
Just something to be aware of.
