Situation:

We create a new PO with budget checking. We set a deferral template, and this PO will apply it. When posting the PO Invoice, the invoice deferral tag is "Yes", and the deferral schedule will auto-generate for this PO invoice. However, the PO budget will be released at the same time. When we decide to recognize these deferral lines, the budget checking will be triggered again.

Error:

If we don't recognize the deferral schedule as soon as the PO invoiced, the released budget may be occupied by other procurement action. And we cannot see the records in budget control statistics table. It is unreasonable.

Requirements:

1. We hope budget control statistics table can have a column to show the budget used by "PO invoiced-deferral schedule-active".
2. Budget control statistics table should reserve the budget, do not allow it to be released for other procurement, after deferral generated.
