Finding a condition

Whereitisn'tpossibletouseasettingtoextractdataofvariablelength,thekeyistofindoneormore

differencesbetweenlinesthatmakeclearhowbigtheregionisfromwheredataneedstobeextracted.

Whilst,forexample,aproductdescriptionmayextendovertwolines,otherdata-suchastheunitprice

-willneverbelongerthanoneline.Eithertheareaaboveortheonebelowtheunitpricewillbeempty

whentheproductdescriptioncoverstwolines.

SuchadifferencecanthenbeusedasaconditioninaConditionsteporaCaseinaMultipleConditions

step.

AConditionstep,aswellaseachCaseinaMultipleConditionsstep,canonlycheckforonecondition.

Tocombineconditions,youwouldneedascript.

Using a Condition step or Multiple Conditions step

UsingaConditionstep("Conditionstep"onpage253)oraMultipleConditionsstep("MultipleCondi-

tionsstep"onpage256)onecoulddeterminehowbigtheregionisthatcontainsthedatathatneedsto

beextracted.

IneachofthebranchesundertheConditionorMultipleConditionsstep,anExtractstepcouldbe

addedtoextractthedatafromaparticularregion.TheExtractstepscouldwritetheirdatatothesame

field.

Note: Datacannotbeextractedmorethanonceinanyrecord,unlesstheExtractstepsaremutu-

allyexclusive.ThisisthecasewhentheyarelocatedindifferentbranchesofaConditionstepor

MultipleConditionsstep.

InsideaDetailtable,multipleExtractstepsmayextractthesamedatabuteachofthemwillcre-

ateanewchildrecordintheDetailtable.

IfyouticktheAppend values to current recordoptionwhenseveralstepsareextractingthesame

field,thestepwillerrorout.

CreateandedittheExtractstepinthe'true'branch,thenright-clickthestepontheStepspane,

selectCopyStep,andpastethestepinthe'false'branch.Nowyouonlyhavetoadjusttheregion

fromwhichthisExtractstepextractsdata.
