parser failed on packing slip scan for net a credit memo against a matched invoice error parsing failure

TL;DR

Fix this agent run by acting on the exact failure first: reject the low confidence parse, re-extract the packing slip fields using the document layout for that supplier, and validate the order number, quantities and dates against the receipt before continuing. Then complete the task in one verified pass: load the original matched invoice and the credit memo side by side and confirm the memo references the same order and tax treatment before netting. Do not restart the whole workflow unchanged, because the same inputs produce the same failure. Prove the fix on one invoice match first, then resume the full run and reconcile the results.

Use this when

• An agent run fails with this exact problem: parser failed on packing slip scan for net a credit memo against a matched invoice error parsing failure.
• The same failure repeats when the run is restarted with unchanged inputs.
• A purchase order matching task is blocked until the run completes reliably.

Not for this skill when

• The notice is a platform outage from the vendor or the network. Resolve that first, then return here if this problem remains.
• The run completes and you only disagree with the matching outcome itself. That is a finance owner decision, not this failure.

Steps

1. Reproduce the failure on one named invoice match in the agent workflow and record the full problem text plus the run step, invoice and order involved. Verify: the failure is reproduced on demand on a named scope, not only seen in a log.
2. Apply the specific fix for this problem: reject the low confidence parse, re-extract the packing slip fields using the document layout for that supplier, and validate the order number, quantities and dates against the receipt before continuing. Then complete the task in one verified pass: load the original matched invoice and the credit memo side by side and confirm the memo references the same order and tax treatment before netting. Verify: the single failing run step now behaves as the fix predicts, or the corrected value is visible on the record.
3. Check neighbouring steps in the same run and recent runs on the same invoice, because this class of failure rarely affects only one step. Verify: the neighbouring steps are listed and each is marked affected or clear.
4. Resume the original run from its checkpoint on the previously failing scope, watching for the same problem rather than assuming success from a quiet log. Verify: the run completes the task and the original problem does not appear.
5. Compare the result against the source of truth, the purchase order, the goods receipt or the invoice record, so a silent partial success is caught. Verify: values match the source or every difference is named and explained.
6. Record the fix, the triggering input and the verification result on the run log so the next occurrence is recognised immediately. Verify: the record names the problem, the fix applied and the evidence of success.

How to fix - parser failed on packing slip scan for net a credit memo against a matched invoice error parsing failure

The alternate phrasing for the same failure in the agent workflow. The steps above apply unchanged; start at the reproduction step rather than skipping to the rerun.

Why it happens

The packing slip layout differed from the layout the parser expected, so a field was read from the wrong position and the extracted values failed validation or matched nothing. In this run the affected task was netting a credit memo against a matched invoice, which is why the failure surfaces as a matching problem rather than a generic run error.

Edge cases

• The order, receipt or invoice changed while the run was stopped. Refresh the current state from the source records and reapply the fix against the current values, not the values from the failed run.
• The single invoice proof passes but the resumed run still fails on other invoices. Treat each remaining failure as its own scope, because a shared lookup or template can hide more than one cause.
• The run output and the source records disagree. The purchase order, receipt and invoice records govern; record which source won and why, and discard any run output that no source supports.

Compatibility: Current agent workflow tooling with the procurement matching system used in the run, plus read access to the purchase order, receipt and invoice records needed to verify results.
