Adjusting the Project Start Date

[tahajassim]

I have created a project which the planned start date was set to 1 Feb 2017 and then in the process I have discovered that the correct planned start date is 15 Jan 2017! Having used MS Project, it was very clear that I just needed to update the planned start date for the project and that should have fixed it, but it seems I am unable to do so!

It seems once the project is started and you start reporting some progress, you cannot adjust the planned start date to an earlier date.

I have tried searching the community but unfortunately I was not able to find a solution to this problem! I am really sure, I am not the first one who faced such issue

Our [London[ instance has this property turned ON but still changes to Project Planned Start Date are discarded after entered. Any additional suggestions?

I just realized there is another property which needs to be turned OFF for cases when you need to update the Project Start Date. 

com.snc.project.rollup_project_start_date needs to be OFF otherwise the Project Start date will be set based on the earliest start date of project tasks.
