For a few days I'm trying to write the assignment progress for a specific task for a specific date. For example: I'm able to set the overall progress of the task but not the actual work that resource did at a given date. We are able to do that using Project Pro on the Task Usage view, but we need to automate some actions based on a file generated by another system and that's why i'm working in this solution but I could not find any object that would allow me to save the actual work value for a date. I'm using the CSOM library and Project Online.

EDIT:

Sorry if I was not clear for the first time... Basically, I need to get and set how many hours a resource worked in a single task for a single day. This can be done through the Task Usage view in the Project Pro (image below). I NEED to do this using CSOM and Project Server. I was able to get and set data for the resource and its assignments, but not by day, as I need.

Here is the image of the screen I'm talking about.

This problem is driving me crazy! Any help would be very appreciated.

Thanks in advance!
