loading the data from fullload datasouc and deltaload datasource into ODS

Hi

Im planning to extract the data from QMEL table. But for

New Records -

> I need to consider the ERDAT as a delta field.

Updated records -

> I need to consider the AEDAT as a delta field.

So if i suppose create the two datasources one for full load and one for delta load.

Then Can i directly map these two datasource(Full Load datasource and Delta Load Datasource) without InfoSource or with InfoSource ????

Please let me know
