Budgeting: How to define multiple versions of Budgets within one Fiscal year

Hi all,

I´m facing the issue, that my customer is running a rolling forward plan budgeting. Therefore, they need to update the current budget with the forecast, reported by the departements but want to keep the history (for reporting purpose).

A solution could be to define one budget per period, but this won´t meet the requirements.

Question: What about versioning of Budgets. I know, that there is a column in the GL_BUDGET_VERSIONS table, but I don´t understand, how to accomplish this in a functional way?.

By the way and not so unimportant: Customer is on e-Business Suite, R 12.1.3!!
