ABAP Query SQ01 - get the data using SUBMIT.

I'm using ABAP Query SQ01 and try to get the data using function LIST TO MEMORY  and WRITE LIST resulting garbage value.

Try the suggestion give our fellow SCN members in this link   http://scn.sap.com/thread/2122861 but still not resolved. Appreciate if there is any idea and input on this.

   call function 'LIST_FROM_MEMORY'

     tables

       listobject = listtab.

 

 

call function 'WRITE_LIST'

* EXPORTING

*   WRITE_ONLY       = ' '

   tables

     listobject       = listtab

* EXCEPTIONS

*   EMPTY_LIST       = 1

*   OTHERS           = 2

.

           .

 

call function 'LIST_FREE_MEMORY'

  tables

    listobject       = listtab

           .

 

   call function 'GUI_DOWNLOAD'
