How to load 0customer_text by ALE delta

Question

Hi,
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 ?
Thankfully,

hi Mohamad,
try if generic delta helps.
RSO2, give your datasource master text name in 'texts', and create. click generic delta button, and choose 'calendar day', and field nm 'UPDAT'.
safety upper limit interval = 1, leave lower limit blank.
click save, in next screen mark field KTOKD for selection. and save. replicate to bw, and map NAME1 to TXTMD or TXTSH or TXTLG.
another way is try without click 'generic delta' but mark ERDAT UPDAT as selection, later in bw create 2 infopackage, one with ERDAT as selection and the other with UPDAT as selection in infopackage, and can choose type 0 (get yesterday), or 6 (abap routine) and put routine for both
ERDAT
data: l_idx like sy-tabix.
          read table l_t_range with key
               fieldname = 'ERDAT'.
          l_idx = sy-tabix.
          l_t_range-low = sy-datum.
          append l_t_range.
          modify l_t_range index l_idx.
          p_subrc = 0.
UPDAT
data: l_idx like sy-tabix.
          read table l_t_range with key
               fieldname = 'UPDAT'.
          l_idx = sy-tabix.
          l_t_range-low = sy-datum.
          append l_t_range.
          modify l_t_range index l_idx.
          p_subrc = 0.
hope this helps.
