Creating a data mapping workflow
AdatamappingworkflowalwaysstartswiththePreprocessorstepandendswiththePostprocessor
step.Thesestepsallowtheapplicationtoperformactionsonthedatafileitselfbeforeitishandedover
tothedatamappingworkflow("Preprocessorstep"onpage249)andaftertheDataMappingworkflow
hascompleted("Postprocessorstep"onpage258).
Whenyoucreateanewdatamappingconfiguration,thesestepsareaddedautomatically,butthey
don'tactuallydoanythinguntilyouconfigurethem.
InbetweenthePreprocessorandPostprocessorstep,theworkflowcancontainasmanystepsas
neededtoextracttherequireddata.
Definingpropertiesandruntimeparameters
Beforeaddingsteps,definethepropertiesandruntimevariablesthatyouwillneedinthedatamapping
configuration.
Adatamappingconfiguration'spropertiesholddatathatcanbeusedthroughoutthedatamapping
workflowtocompareagainstinconditionsortocomplementtheexistingdata.
Runtime parametersarepropertiesthatwillpassinformationfromOLConnectWorkflowtothedata
mappingconfiguration.
AllpropertiesaredefinedinthePreprocessorstep.
Formoreinformationsee"Propertiesandruntimeparameters"onpage227.
Addingsteps
Extractingdataisthemainwaytobuildadatamappingworkflow;see"Extractingdata"onpage229.
Extractsteps,ConditionstepsandRepeatstepscanbeaddedafterselectingdataintheDataViewer.
AllstepscanbeaddedviatheStepspane:
1. IntheextractionworkflowontheStepspane,selectthestepafterwhichtoaddthenewstep.
2. Right-clickontheStepspaneandselectAdd a Step;thenselectoneofthesteptypes.
ToaddafirstStepinsideaRepeatorConditionstructure,clickontheinitialstepoftheRepeat/Condi-
tionstructure.ThishighlightstheentirestructureandanyStepyouaddnowwouldbepositionedimme-
diatelyafterthestructure.Clickoncemoreonthestructure'sinitialsteptohighlightitalone.Thenext
Stepaddedwillnowbepositionedasthefirstchildinsidethestructure.
Editingsteps
ThepropertiesofeachstepintheextractionworkflowbecomevisibleintheStep propertiespane
whenyouselectthatstepintheStepspane.
ThenameofeachstepisshownintheStepspane.YoucanchangeitunderDescriptionintheStep
propertiespane.
Theotherpropertiesaredifferentpersteptype;see"Steps"onpage248.
