I've been undertaking a study of the differences between the Sage financial reporting and management features and that of other leading "FP&A" solutions in the industry.
One of the leaders in this industry is Datarails (www.datarails.com).
Here is a demo of that solution that I found on youtube - https://www.youtube.com/watch?v=mkFTZNbwLms
One of the features that it exhibits is budget approval and budget locking by senior management. I know that the Operating budgets module has an approval feature but the standard financial budget management does not. Could there be new functions added under the Financials > Budgets menu block that would allow someone with the appropriate access level to approve the budget before it could be used for financial reporting and in addition to lock/unlock the budget to provide further changes and/or release for additional changes?
