(Formoreinformationaboutdetailtables,multipledetailtablesandnesteddetailtables,see"Detail
tables"onpage298.)
DetailtablesarecreatedwhenanExtractstepisaddedwithinaRepeatstep.TheRepeatstepgoes
throughanumberoflinesornodes.AnExtractstepwithinthatloopextractsdatafromeachlineor
node.
Howexactlythisloopisconstructeddependsonthetypeofsourcedata.
Tip: Tobreakoutofaloopandimmediatelyjumptothenexttaskfollowingthecurrentloop,use
anActiontaskandsetitsactiontoBreak out of repeat loop.
Notethatsuchloopsworkwellwhenthedataarestructureduniformly,e.g.whenallrowshavethe
samenumberofcolumns,andwhendetaildataalwaysstartatthesamepointintheline.Obviously,
thatisnotalwaysthecase.
Howtoextracttransactionaldatathatisstructureddifferentlyisexplainedinanothertopic:Extracting
datawithascript.
Thetopic:"Extractingdataofvariablelength"onpage245explainsafewwaystoextractdatafroma
variablenumberoflinesintoonedatafield.
