Procurement transactions exceed PO encumbrance

Hello,

In PeopleSoft 9.2, we have an instance where a procurement cardholder had multiple transactions that were linked to the same purchase order and the encumbrance was exceeded. There wasn't a warning that the encumbrance was exhausted by other transactions during the procurement card statement reconciliation process or (after the procard voucher was built) during the voucher budget check. The voucher budget check did liquidate the PO encumbrance for the originally encumbered amount properly.

I'd appreciate any suggestions/recommendations to help with this procard scenario.

Thank you,

Laurel
