I have a Function Group, where I have added a dialogue program with a sub-screen with SELECTION-OPTIONS...
SELECTION-SCREEN BEGIN OF SCREEN 1010 as subscreen.
SELECTION-SCREEN BEGIN OF BLOCK 1 WITH FRAME TITLE text-s01.
SELECT-OPTIONS: s_parno for /sapsll/pntbp-partner.
SELECTION-SCREEN END OF BLOCK 1.
SELECTION-SCREEN BEGIN OF BLOCK 2 WITH FRAME TITLE text-s02.
PARAMETERS: p_vadrs AS CHECKBOX.
SELECTION-SCREEN END OF BLOCK 2.
SELECTION-SCREEN END OF SCREEN 1010.
In the PAI of the parent screen 1000, I cannot access the content of s_PARNO. It is empty.
And since the sub-screen is generated, SAP reminds me that changes to the PAI of the sub-screen is futile.
