Thanks for the responses but i believe i have fixed the issue - this was down to the Earned Value Calculartion settings within P6 Admin menu.
When calculating Earned Value Calculation from a baseline, i was configured to "Budgeted values with planned dates" which was populating my Baseline dates against the baseline early S/F / baseline actual S/F fields for in progress activities and giving me spurious dates in my main Project BL fields.
I have since amended that setting to "Budgeted values with current dates" which uses the live activity dates at the point of baseline and populates the main BL Project Start / BL Project Finish fields with these dates. The BL Actual S/F columns are populated only for activities this applies to at the time of Baseline.
Alexandre's advice is on-point - Ron's paper is money.
Short answer - "Planned" dates in P6 are quite peculiar.
1. For any given project, Planned Dates = Early Dates, UNTIL an Actual Start is recorded. Then Planned Dates are frozen at the values they held when an actual start was recorded. This usage makes sense for a very specific workflow case - for all others it makes no sense at all. In particular, one must be sure to record ALL progress before incrementing the Data Date. While accepted as good practice, this is far from universal.
2. In the absence of an embedded Baseline schedule, the "Baseline" dates and bars are actually "Planned" dates and bars.
3. When an embedded Baseline schedule is present, the "Planned" dates from the Baseline are the ones that get used as "Baseline" dates - e.g. in Baseline bars. This can cause problems if the Baseline includes some progress.
Most of these issues are removed by running a global change as part of the standard update process - replacing "planned" dates with the Actual or Early dates.
Good luck, tom

a few years ago, Ron Winter wrote the following paper about Dates fileds in P6; I suggest you read it carefully, you will find all the explanations you need.

Andy,
I understand that a baseline when attached to an updated progress schedule will never and shall never be changed and remain intact accordingly.
I suggest you check the default baseline setting in the project window. Either it is set to Project baseline or User baseline.
