generic extractor

hello,

thank you all for your ideas. I'm faced with two choices, and I want to know what the right:

1) I installed five standard extractors on Shipments. But these extractors do not bring all the fields I need. To solve this problem, I chose to create a view, and from that view, creating generic extractors for transaction data. Will I need to code in ABAP?

2) How these generic extractors manage the full load, Delta, Init?

3) With LO Standard Datasource, i have the concept of Filling the SetUp Tables....Now what about a generic datasource?
