We are loading MATMAS IDOC . We are mapping RawMATMAS to CanonicalGiftItem in datahub-extension.xml file. After composition CanonicalGiftItem is created with 'INVALID PRIMARY KEY' error.
We are doing some customizations in GroupingHandler. We are not comfortable using grouping handler and composition handler . Dont no when we call new CompositionGroup in grouping handler what exactly happens. Sample file is attached.
Please let us know how to use custom grouping handler, composition handlerlink text
