Please read everything before doing anything ... mistakes can be costly.

*** You have just wiped out all actual costs for the project. ****
You need to have some way to map the Actuals from your Accounting System to
line items in your Project. Most accounting systems aggregate costs at a
much higher level than the detailed tasks in Project.
For the sake of simplicity, I assume you have a field such as Text1 in the
Task Usage View that contains job numbers for tasks... this is what maps to
the cost accounting system.
You can enter some type of one line summary task (we call it Cost Data) and
underneath that we have indented every job number costed in the Cost
Accounting System. That is: the name of the task is the same as the job
number-- JN 10A103A. No resources or work, just Job Numbers. The job
numbers also appear in the Text1 column for that row.
On the right side of the Task Usage View, right click on the Details Column
and make sure the actual costs row is displayed. On that same view, format
the time scale at the top to be something equal to your cost accounting
system. For example, monthly.
Each month, you can cross reference your output from cost accounting, by Job
Number and manually key the dollars into the Actual Cost row for the Job
Number Rows. The data needs to be calculated "monthly." You can now export
BCWP, BCWS, and ACWP to Excel using the Export Wizard and graph away.
VB Code can be written to populate this information for you, contact me if
further assistance is needed in that area.
