Any suggestions? THANKS FOR ADVANCE

PERFORM MASSENAENDERUNG USING CON_NO.
LEAVE PROGRAM.
ENDIF.
" START-OF-SELECTION .
if not sy-batch is initial.
macro_import_tcndb_for_batch.
l_maspar[] = p_maspar[].
loop at l_maspar where not abap_prog is initial.
clear l_maspar-abap_prog.
modify l_maspar index sy-tabix.
endloop.
p_maspar[] = l_maspar[].
endif.
IF P_MASCNG[] IS INITIAL.
