Plan cost for resources

Hello Gurus,

I have mapped cProject scenario as below (using version 4.5) -

Step 1 - Operative cProject structure will be created (in Structure Tab) and roles will be created for the project (Resource Tab)

Step 2 - The cost/revenue rates maintained (in config) for those roles will get determine in operative project (Resource Tab)

Step 3 - Staffing or resources (Business Partner) will be done for the role (Resource Tab)

Step 4 - The roles and resource planning will be done for individual task (Main Tab - Structure & Role Tab for the Task) by entering work hours for individual role & resource combination. I may have several roles & resource combination assigned to individual task.

Note - No cost/revenue rate will be maintained for the task (on Additional Data Tab)

Question - Will system calculate plan cost for the individual task considering assignment of role, their plan working hours and rates as explained in above steps automatically or any other setting is required to achieve this

Please let me know in case you need any further inputs

Thanks in advance
