Need you help !!! -- How to set PACKAGE SIZE in CURSOR?

Question

Dear experts:
Does anybody know how to set the package size if you use cursor in your abap program?
My scenario is to select all the data from MARA table in which the data volumn is very big, and then process for some specific logic. When I try to select them into one internal table or use CURSOR without package, my abap program will abort after running for around 1 hour. So I was thinking if I can use cursor and set the PACKAGE SIZE like 10,000 and process the data by batch.
Here is my sample code:
OPEN CURSOR: CUR_MARA_TBL FOR
SELECT * FROM MARA.
DO.
FETCH NEXT CURSOR CUR_MARA_TBL INTO CORRESPONDING FIELDS OF WA_MARA_TBL.
IF sy-subrc = 0.
......Detail logic......
ENDIF.
ENDDO.
I would appreciate if anybody can let me know how to set the package size based on the sample code above, or any webpage/article about that.
Any reply would be appreciated and thank you all in advance!
Best Regards.
Tim

Answer 1

The Spark List's layout property has the requestedRowCount and requestedMinRowCount properties.
You can either set a new layout property on your List like this:
<s:List>
        <s:layout>
            <s:VerticalLayout requestedMinRowCount="1" />
        </s:layout>
    </s:List>
or reskin the List and modify the VerticalLayout in your copy of ListSkin.
