Error code: CST_DPROC_UNCOSTED_COGS_TXN
COGS is the last domino in a chain: the sales-order issue behind it must cost first, and that issue needed an inventory layer with a real cost, which never formed, usually because the receipt that should have created it came in costless. You can't fix the last domino; you stand up the first one.
The sales-order issue never costed (no layer with a cost), so COGS has nothing to distribute.
