Budget at completion, Earned value cost, Planned value cost is double of what is mentioned in the resources

1st ALWAYS ALWAYS 

go to the projects directory 

makes ure that your project is highlighted

click on the resources tab 

on the lower right under resource assignments make sure that 

RESOURCES and be assigned to the same activity more than once is NOT checked 

this will eliminated double dipping the resource or adding it again if your re-import an excel file 

Thanks for the reply, Zoltan. I checked the prog, no double resoucing was done but what had happened is that there was budgeted cost assigned in resource tab and also in expense tab so the two were doubling up to display the budget at completion. I removed the budgetd cost from expense tab now to keep it just as the non-labour resource.

I never ever use expenses glad you figured it out
