SAP Note 24814 - SAPSQL_ARRAY_INSERT_DUPREC in SAPLCOMV

Symptom:

An update termination occurs when confirming an intermediate status or when saving after the signature has been entered.

Cause and prerequisites

If a characteristic PPPI_AUTOMATIC_VALUE is valuated several times in the process order under the same characteristic name, an update termination occurs.
The same characteristic may not be contained several times in a message with an identical valuation.
The attempt to insert two identical records in database table COME leads to a termination during the SAP SQL array insert.

Solution
Create a new process order in which the error does not occur.
Create and send a new control recipe.
Process the new PI sheet.
