How to catch Delta Initialization and Delta Update in a Function Module

Question

Hi Experts:
I'm developing a FM to extract data from R3. I wonder if anybody knows how to catch when i'm making a delta initialization and a delta update in my FM, because i have different parameters and routines from each one.
Thanks in advanced.
Points for helpfull answers.

Hi,
Keep one dummy date field in the structure. Make this dummy date field as delta enabled field. When you do Init load this date field value will be blank and next time when you do load it will have the last upload (in this case init load) date. You have to write a code before open cursor as below:
      LOOP AT s_s_if-t_select INTO l_s_select.
                              WHERE fieldnm = '(dummy date field name)'.
         l_date = l_s_select-low.
      ENDLOOP.
l_date will have the last upload date. This you can use to select the delta records from the table or for the further processing.
If you want to check the value during Init or delta load, go to RSA3 and debug it(Don't use F - Full load. Use I or D in the update field).
Hope this helps.
