Encumbrance accounting for cancelled PO

The accounting entries are created correctly for an encumbered PO.

However, when the PO is cancelled the obligation is reversed in the month that it is cancelled as opposed to each profiled amount.

Although the net effect by the end of a year would be the same, it is not as we were expecting.

eg, in the very simplest form (i.e. no partial receipts, invoices, partial cancel)

• A PO is raised in Nov spanning Nov to Jun (8 periods at £50 each)
• This is cancelled (£350) in Dec
• The accounting entries show the cancellation as a reversal of the commitment (£350) in Dec
