ADFDI is another Data Import tool in oracle fusion to insert the data in the Oracle Cloud. ADFDI is the same as WebADI in Oracle Apps which is totally integrated with the application. This works online as compared to the FBDI which works offline means we prepare the data offline so ADFDI provided the real time real time data validation.
Second good thing in ADFDI is that , it provided real time interaction with Fusion Application. It means you select values from List of Values from the ADFDI Excel sheets. Like BU ,Supplier, Its Sites. So if you are entering any wrong information in ADFDI template which does not exists in Fusion Application , it will give error on the same time when you are entering this values in the ADFI template but this is not possible in FBDI. FBDI does not provide your selection and list validation from the Application. in FBDI you will get errors when you will trying to import data in fusion Base Tables.
Fusion has given you ADFDI for each important function of the Business like (Supplier, customer, AP Invoice, AR Invoice, GL Journals, Fixed Assets, Purchase Orders and many more).
