Steps for Using PA WebAdi Budget Upload

Hi

We are using Form based screen to enter and maintain Budgets within Project Costing Module.

We wanted to use the functionality of loading Budgets using Spreadsheet ( PA WebAdi Budget Spreadsheet).

Few questions around this:

1. Can we use Budget WebAdi Upload when we are using Form Based Budget for enter and maintaining budget or Do we have to upgrade to us Plan Types to be able to use WebAdi Budget Upload.
2. Which Seeded Project Standard Responsibility has WebAdi Spreadsheet for Budget available
3. Any metalink documentation that we can refer for this.

Thanks
