Answer 1

What do you mean by ALV check box selection screen?
ALV and selection screen check box( you are mixing two cases in your Question).
You need use the Function moduel in the user command to get the updated data.
in fieldcatalog you have to use INPUT = 'X' and EDIT = 'X' for the columns which ever you want edit.
GET_GLOBALS_FROM_SLVC_FULLSCR
follow the sample code.
REPORT ZTEST_ALV_CHECK MESSAGE-ID ZZ .
TYPE-POOLS: SLIS.
DATA: X_FIELDCAT TYPE SLIS_FIELDCAT_ALV,
IT_FIELDCAT TYPE SLIS_T_FIELDCAT_ALV,

IT_EVENTS TYPE SLIS_T_EVENT.
DATA: BEGIN OF ITAB OCCURS 0,
VBELN LIKE VBAK-VBELN,
POSNR LIKE VBAP-POSNR,
