problem in FM

Hi,

I have created a Function Module, and from the function module i am calling a report program thru "SUBMIT" command.

now in the 'submit' command i add the addition 'exporting list to memory and return'.

after that i read the contents of the list using FM

'list_from_memory'.

now i enter the name of the internal table which i declared in FM. But this is giving me run time error.

for detaild view i post the code down below:-

submit zrpt_mm_045 with s_werks-low = s_werks

with s_mtart-low = s_mtart_low

with s_mtart-high = s_mtart_high

with s_matnr-low = s_matnr_low

with s_matnr-high = s_matnr_high

with s_budat-low = s_budat_low

with s_budat-high = s_budat_high

with s_lgort-low = s_lgort

with rb1 = rb1

with rb2 = rb2

with rb3 = rb3

EXPORTING LIST TO MEMORY AND RETURN.

CALL FUNCTION 'LIST_FROM_MEMORY'

TABLES

listobject = itmatgrp1 ---> from FM

• EXCEPTIONS

• NOT_FOUND = 1

• OTHERS = 2

.

IF sy-subrc <> 0.

• MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

• WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

ENDIF.

endfunction.
