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.

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