IS it mandatory to customize Project Budget account workflow process for Top down budgeting

Hi Folks,

We have defined the Budget and but not baselined the budget.AS we need to enter the Budget accounts,i tried to enter the budget account under Working version - Review budget accounting,but we don't have any option for this.

As we are defining the Top down budget integration,we need to enter the Account code combination under "Review budget accounts".we don't have any option to enter the GL account code combinations.

In Project Costing,while defining the budget we have the option to enter the GL account code combination under "Tools -Review budget account

Same as in Project Costing,Do we have the option to enter the GL code combinations in Project Management without customising the Project Budget account workflow.
