SUBMIT program USING SELECTION-SET goes to GUI SCREEN instead of providing a list.

I am using above code to call IW38 report, which gives a list of orders to be confirmed, user clicks the order from the list and goes to below screen to confirm the order

In case of multiple orders IW38 provides a list of orders and I can call the BAPI to confirm the orders inside a loop.
But in case of 1 record, the transaction IW38 itself goes to the above screen instead of providing a list.

But my code fails and opens a new window for the gui transaction, is there anyway I can get list of 1 record instead of above screen?

Looks like this should be possible by exporting 'X' to memory ID 'G_VARIANT_SAVE' before submitting the report.

Form DISPLAY_LIST_F14 checks if global variable g_variant_save is 'X' - if it is it behaves as if there's more than one hit.
Form VARIANT_INIT_F14 tries to get g_variant_save from memory ID 'G_VARIANT_SAVE' and otherwise sets it to 'U'

did not work unfortunately:
EXPORT value = abap_true TO MEMORY ID 'G_VARIANT_SAVE'..

It still opens the IW32 screen which is in the screenshot.

I feel really stuck here, I tried with reading SUBMIT REPORT documentation but nothing.

@KjetilKilhavnI can see that based on number of rows, different subroutines are getting called.
In case of multiple records, it calls PERFORM call_listviewer_f14.
but with single record, it calls PERFORM fcodes_with_mark_f16.

Is there any way I can call the SUBMIT PROGRAM in some way that sets SY-BATCH = 0?
my Z program is supposed to run as a background job, but it seems SUBMIT RIAUFK20 statement doesn't set SY-BATCH = X.
SY-BATCH = X only when my Z Program is running.

Unable to find any enhancement. 

[KjetilKilhavn]

That's too bad. Either that means VARIANT_INIT_F14 isn't called when you submit the report, or a different value is assigned to variable g_variant_save before DISPLAY_LIST_F14 is called.

Debug to find out. I don't have any other tips.

[KjetilKilhavn]

Perhaps you need to start looking for some other solution than submitting RIAUFK20?

Horrible comment feature, button is disabled and it still takes whatever is typed in.

@KjetilKilhavn eventually SPOOL was used and list was collected with string manipulation from spool output.
Thank you for your suggestion!
