Force Background processing with SUBMIT and keeping results in memory

Question

Hi Everyone
I have a very tricky issue that i need some help with.
I have a developed an RFC that allows a NON-SAP front-end to execute reports in the SAP backend the result of the report is saved in memory and formatted to XML and passed to the front-end where the report is displayed.
Therefore for this to work i have added the following code
g_guid = cl_salv_export_db_storage=>create_guid( ).
  " Set ALV memory parameters
export l_mode = 'M' to memory id 'ALV_EXTRACT_MODE'.
  export l_guid = g_guid to memory id 'ALV_EXTRACT_GUID'.
  "Execute the selected report
  SUBMIT (wlv_report_name)
                     USING SELECTION-SET wlv_variant_name
                     WITH PNPTIMED EQ ' '
                     WITH PNPBEGDA EQ im_begda
                     WITH PNPENDDA EQ im_endda
                     WITH PNPPERNR IN wlr_employee
                     AND RETURN.
data: l_xstring type xstring.
            l_xstring = cl_salv_export_db_storage=>import_xmlstring(
                guid  = g_guid ).
This allows me to get the report results to be passed to the front-end.
This works quite good for most reports but in some cases the reports has a popup message. In this case the execution fails as the report is not executed as a background job (if the report is executed in the background then the popups are ignored).
The issue is that the reports cannot be executed in the background as the memory will then not contain the report results and secondly the client does not want to use the spool for the report results at all. The second constraint is that the client does not want to alter the reports in any form to remove the popups due to the large volumes of reports.
What i have noted is that if the report is executed and i set the SY-BATCH parameter to "X" then it works perfectly (via the debugger). I can change the SY-BATCH value in my code but obviously once the SUBMIT is executed the SY parameters are reset.
My question is: Is there a way to force the SY parameter values when i perform a SUBMIT? Or is there any other possible solution to this issue?

Answer 1

If you want to go with the option of spool, then you can use the following addition
SUBMIT <reportname> to SAP-SPOOL
  SPOOL PARAMETERS <print_parameters>
  WITHOUT SPOOL DYNPRO and RETURN.
and then read the spool,
if you want to go with the option of a background job, then you can use the following addition
SUBMIT <reportname> VIA JOB <name> NUMBER <num> AND RETURN.
<name> and <num> are generated using FM JOB_OPEN, and then you have to close it using JOB_CLOSE.
Thanks.
