8.1.1.11 - Inbound Web Service Error - SBL-EAI-00133: EAI Common Internal Error
This can have an impact on previously working inbound web services, where Error Message was populated, but not considered to require a soap fault.
Note, there is an intended change with 8.1.1.11.7 / 8.2.2.4.7 (i.e Patchset 7) where the generation of a soap fault can be controlled with the existence of a Process Property named 'FaultOnError' . The document above has been updated to reflect this.
