Cash Flow report without resource loading in P6

putting the budget against each activity is resource loading its loading with dollars not manhours

How can I prepare a report with dollars for each activity?

add a resource call LUMPSUM or what ever

filter for all of the activities that you want to cost load

select edit select all

right click and select assign 

then select  resources

then select the new resource that you created

now in the resource tab under budgeted cost

assign the cost for each of teh actyivities

when done you can either select view show on bottom activity usage spreadsheet

or view show on bottom resource usage profile thsi will give you your cost curve

I'd agree that cost loading is most commonly done through resource loading of a lump-sum resource as Zoltan has laid out.  The restriction, "...without resource loading in P6...." can be strictly satisfied by loading costs through the Expenses tab.  Although this is not the stated purpose of the Expenses tab, some contract specifications explicitly require it (not sure why.)  

you can use Expenses to load cost on all activities you want,

add one expense on an activity then export on excel then add the cost and import it again on primavera.

I am not sure that you can get an S curve using expenses

Zoltan, yes you can.  Activity Usage Profile using Cost instead of Units incorporates all the Expense tab data. 

thanks Tom good to know I never uses expenses
