How to transfer large transactional tables from RFC to background ABAP?

Question

Which is preferrable to use ABAP memory, SHARED MEMORY/BUFFER or SHARED ABAP OBJECTS in my scenario:  I have an external application sending two tables to an RFC.  The tables are made up of transaction data and can approach 1 GB in size.
The RFC times out, since it is a dialogue process. Therefore, I programmed the RFC to SUBMIT a background job VIA JOB.
QUESTION: How to import internal table into a program that was submitted via JOB?
Do I have to use SHARED MEMORY/SHARED BUFFER, or can I still use ABAP memory?
Can I send a table in a parameter in SUBMIT WITH construct?
An issue I have encountered is that the result of the IMPORT FROM SHARED BUFFER constructu  is not consistent in consecutive executions. Why would the result of the  IMPORT be inconsistent if the code is exactly the same and the data is exactly the same?
FYI I am building the memory ID dynamically and then sending in SUBMIT WITH parmeter?
Please don't post links to SAP HELP documentation.. I have read it, re-read it and read it again.
I really need expert experience, not generic documentation.
Thanks in advance.

Hi here is an example for the submit command use,
You can call one selection screen from other selection screen program using SUBMIT command.
The syntax is as follows -
codeSUBMIT... VIA SELECTION-SCREEN
USING SELECTION-SET <var>
WITH <sel> <criterion>
WITH FREE SELECTIONS <freesel>
WITH SELECTION-TABLE <rspar>.[/code]
e.g.
The following executable program (report) creates a selection screen containing the parameter PARAMET and the selection criterion SELECTO:
codeREPORT demo_program_submit_rep1.
DATA number TYPE i.
PARAMETERS paramet(14) TYPE c.
SELECT-OPTIONS selecto FOR number.[/code]
The program DEMO_PROGRAM_SUBMIT_REP1 is called by the following program using various parameters:
codeREPORT demo_program_submit_sel_screen NO STANDARD PAGE HEADING.
DATA: int TYPE i,
rspar TYPE TABLE OF rsparams,
wa_rspar LIKE LINE OF rspar.
RANGES seltab FOR int.
WRITE: 'Select a Selection!',
SKIP.
FORMAT HOTSPOT COLOR 5 INVERSE ON.
WRITE: 'Selection 1',
/ 'Selection 2'.
AT LINE-SELECTION.
CASE sy-lilli.
WHEN 4.
seltab-sign = 'I'. seltab-option = 'BT'.
seltab-low = 1. seltab-high = 5.
APPEND seltab.
SUBMIT demo_program_submit_rep1 VIA SELECTION-SCREEN
WITH paramet eq 'Selection 1'
WITH selecto IN seltab
WITH selecto ne 3
AND RETURN.
WHEN 5.
wa_rspar-selname = 'SELECTO'. wa_rspar-kind = 'S'.
wa_rspar-sign = 'E'. wa_rspar-option = 'BT'.
wa_rspar-low = 14. wa_rspar-high = 17.
APPEND wa_rspar TO rspar.
wa_rspar-selname = 'PARAMET'. wa_rspar-kind = 'P'.
wa_rspar-low = 'Selection 2'.
APPEND wa_rspar TO rspar.
wa_rspar-selname = 'SELECTO'. wa_rspar-kind = 'S'.
wa_rspar-sign = 'I'. wa_rspar-option = 'GT'.
wa_rspar-low = 10.
APPEND wa_rspar TO rspar.
SUBMIT demo_program_submit_rep1 VIA SELECTION-SCREEN
WITH SELECTION-TABLE rspar
AND RETURN.
ENDCASE.[/code]
=> To leave a called program, you can use SUBMIT .... AND RETURN. by choosing F3 or F15 from list level 0 of the called report.
Hope this helps.
