... EXPORTING LIST TO MEMORY

Does not display the output list of the called report, but
saves it in ABAP/4 memory and leaves the called report
immediately. Since the calling program can read the list from
memory and process it further, you need to use the addition ...
AND RETURN. Also, since the called report cannot be requested
for printing, the addition ... TO SAP-SPOOL is not allowed
here. You can read the saved list from SAP memory with the
function module 'LIST_FROM_MEMORY' and then (for example) store
it in the database with EXPORT. You can process this list
further with the function modules 'WRITE_LIST', 'DISPLAY_LIST'
... of the function group "SLST".
