At PAI you can read the current cursor position.

GET CURSOR FIELD <f> LINE <lin> ...

In addition to the information given under Finding Out the Cursor Position , field <lin> contains information on which row of the table control the cursor is currently on. You can also use


TABLE CONTROL

These are the screen elements used to display tabular data they can be called
as screen tables( like STEP LOOP).To use table control we have to create it on the screen using SCREEN PAINTER(SE51) and declare a control variable of TYPE TABLEVIEW using CONTROLS statement in the ABAP program. We have to use LOOP .. ENDLOOP statement in both PBO and PAI with or without AT int_table parameter. IF AT int_table parameter is not used than we have to place a MODULE call between the LOOP...ENDLOOP statement to fill the screen table rows from the ABAP program in PBO and program our own scrolling functions
using OK_CODE field.
Having a parallel loop(at screen table rows & int table rows) by using parameter 
AT int_table makes the ABAP code simple.
A special structure of type CXTAB_CONTROL is used to set/get various
attributes of table control at runtime like CURRENT_LINE ,TOP_LINE.

ABAP declaration

CONTROLS: tab_con TYPE TABLEVIEW USING SCREEN nnnn
Here tab_con is the same name we used in screen for the table control.
This ABAP statement will declare a control variable that will be used to access
the table control , and set it's various attributes like number of fixed columns(tab_con-FIXED_COLS) ,total number of records it will display(tab_con-LINES).It is of type CXTAB_CONTROL and is a deep structure(structure containing structures).
