Symptoms
The WCF-SAP NCO adapter does not log any error message when it receives an IDOC that contains fields that are longer than the allowed length.
Cause
When the IDOC is transferred to SAP, the fields are misaligned when the IDOC is processed. This issue occurs because the WCF-SAP NCO adapter does not validate the created IDOC against the IDOC schema.
