     at com.sap.aii.mappingtool.tf7.DummyHandler.putValue(Ljava/lang/Object;)V(DummyHandler.java:98)
     at com.sap.aii.mappingtool.tf7.rt.LeafStructureNode.putValue(Lcom/sap/aii/mappingtool/tf7/IOutputHandler;Ljava/lang/Object;)V(LeafStructureNode.java:33)
     at com.sap.aii.mappingtool.tf7.AMappingProgram.processNode(Lcom/sap/aii/mappingtool/tf7/rt/AStructureNode;)V(AMappingProgram.java:429)
