Project Changing % Complete when entered
Why does MS Project change the % Complete value entered?
We have a task with a Start date of 11/12/25 and Finish date of 1/20/27. The duration is 223.9 days based on a 4 day/10 hrs per day calendar (it is a long lead time material procurement task). The status date is 1/5/26 and the task has an Actual Start of 11/12/25. When I enter 10 in the % complete column and hit enter, Project changes this to 0%. When I enter 15 in the % complete column and hit enter, Project changes this to 5%. When I enter 50 in the % complete column and hit enter, Project changes this to 44%.
I believe % Complete is either calculated or entered, but it seems if you enter a value in this field, Project shouldn't change it. What causes Project to change your % Complete value entered, and how do you get Project to display the desired % Complete for a task like this?

Brett_Phifer_SCI,
Somethings not quite jelling with the scenario you provide. When I set up a task with the parameters stated, the finish date is 12/8/26, not 1/20/27. Are there some non-working days thrown in (e.g. holidays)?
You mention the status date is 1/5/26 but that is irrelevant when entering percent complete directly into the % Complete field.
A few questions:
- What is the task type?
- Is the task auto-scheduled?
- Are any resources assigned and if so, what is the resource's Base Calendar?
- Are you by chance entering a value into the Actual Duration field, Remaining Duration or Actual Work fields in addition to entering a value in the % Complete field?
