A field that its occurrence is 0...1 is not mandatory.

If the schema was generated by you (not imported) then you can change the XSD and make that field mandatory.

Then use schema validation in the Adapter engine to make the message fails when the field restriction is not met.

This way, you will use the standard mechanism of SAP PI.

Hi Kiran,

Use below UDF.

public String throwMandatoryFieldException(String fieldName, String fieldvalue, Container container) throws StreamTransformationException{
if (!fieldvalue.equals(""))
  return fieldvalue;
  else
  throw new StreamTransformationException("Mandatory field " + fieldName  + " is missing!");
  }

Mapping:

Hi Kiran

Please delete the duplicate thread.

You can use MapwithDefault function from the Graphical mapping editor to avoid error.
