Error description

Local fix

• Either implement a default custom type converter as described
  in the below documentation chapter:
  http://www.ibm.com/support/knowledgecenter/SSQP76_8.7.1/com.ibm.
  odm.dserver.rules.designer.author/cobol_topics/tsk_bom_custom_
  types_define.html
  or provide a "default date" in the COBOL data such as
  01/01/0001 or 99/99/9999 for instance
  

Problem summary

• When cobol date field is empty or an incorrect date format is
  specified in the BOM. The following exception is thrown when
  the copybook is generated from the xom:
  com.ibm.rules.hbr.runtime.
  RulesExecutionManager execute
  SEVERE: GBRZP6002E A RawDataRuleExecutionException occurred
  during rule execution Exception occurred when converting date-
  debut-antecedent
  ilog.rules.res.session.rawdata.internal.runtime.
  ConversionException: Exception occurred when converting date-
  debut-antecedent.
  

Problem conclusion

• A meaningful exception is thrown and the support of
  DateConverters has been improved.
  

Temporary fix

• Implement a custom type converter as decribed in:
  http://www.ibm.com/support/knowledgecenter/SSQP76_8.7.1/com.ibm.
  odm.dserver.rules.designer.author/cobol_topics/tsk_bom_custom_ty
  pes_define.html
  or provide a "default date" in the COBOL data such as
  01/01/0001 or 99/99/9999 for instance.
