Detail tables
AdetailtableisafieldintheDataModelthatcontainsarecordsetinsteadofasinglevalue.Detail
tablescontaintransactionaldata.TheyarecreatedwhenanExtractstepisaddedwithinaRepeat
step;see"Extractingtransactionaldata"onpage235.
Inthemostbasicoftransactionalcommunications,asingledetailtableissufficient.However,itispos-
sibletocreatemultipledetailtables,aswellasnestedtables.Detailtablesandnestedtablesaredis-
playedasseparatelevelsintheDataModel(see"TheDataModel"onpage260).
DetailtablescanbeincludedinatemplateviaaDynamic Table;see"DynamicTable"onpage742.
Renamingadetailtable
Renamingdetailtablesisespeciallyusefulwhentherearemoredetailtablesinonerecord,orwhena
detailtablecontainsanotherdetailtable.Forthisdetailtable,‘products’wouldbeabettername.
