Hi,

First time in this community and an unexperienced user of MS Project, so would appreciate any help.

There is a pretty extensive schedule in MSP originally created by someone else which is maintained by a different "someone else", and this "different someone else" sends me the freshly updated schedule weekly so that I can run a few reports on the project progress (or a lack of thereof).

This "different someone else" is not exactly a super user of MSP either, so today he surprised me with this question: When I tried to update the “Actual Finish”, the “Finish” column changed to the same date. What could be wrong?
They updated the project weekly multiple times before but never mentioned this problem, hence I assume this is new. So what could be wrong this time and why adjusting actuals made original dates change accordingly?

Apologies for what probably is a very naive question and many thanks

P.S. In case if anyone thinks this has something to do with baselines - and fyi - we have baseline start and finish columns in this schedule, and these are "locked", meaning we don't change them unless with the mngt's permission. The last baseline (so far there's a total of three) was set back in Sep 2013.
