How to load 0customer_text by ALE delta
I would like to load customers name of one account group by delta.
The ocustomer_text DataSource has no selection of account group, so it extracts all the customers text.
I tried to create a new datasource which is a view that have the table kna1, and added the field "account group" as selection.
It seems well, but the problem is, that when I try to load data by delta I get nothing.
So,Can anybody explain how can I load text by delta from the table kna1 ?
