The LINE parameter in the GET or SET statement refers to the system field SY-STEPL, the special loop index in the flow logic.

You calculate the internal table line that corresponds to the selected table control line as follows:

Line = <ctrl>-TOP_LINE + cursor position - 1.

The GET CURSOR statement sets the return code as follows:

SY-SUBRC = 0 if the cursor was positioned on a field

SY-SUBRC = 4 if it was not.

You can position the cursor on a particular element in the table control using the LINE parameter in the following statement:

SET CURSOR FIELD <field_name> LINE <line>.

You can also use the OFFSET and LINE parameters together.

Hi Ashish Gupta(AG),

When you display records in the table control and you get all the records from the database table.

Now at CHANGE button, you want modify the existing record.

Use this code to modify your data. Its working.

First populate your internal table from the database table.

In the table control keep the name of the I/O fields same as of <internal_table-field_name>.

for example : movie_tab-rel_year.

When you navigate to table control (probably on another screen).

Automatically, the records from internal table are populated on to the table control.

Now if you make some changes in your data and click 'CHANGE', use this code to modify your data in database table.

****AT SCREEN FLOW LOGIC********************************************************************************

PROCESS AFTER INPUT.

LOOP WITH CONTROL MOVIE.

MODULE SAVE_DATA.

ENDLOOP.

**********************************************************************************************************************

****MODULE SAVE_DATA*************************************************************************************

MODULE SAVE_DATA INPUT.

OK_CODE = SY-UCOMM.

CASE OK_CODE.

WHEN 'CHANGE'.

MODIFY MOVIE_TAB INDEX MOVIE-CURRENT_LINE. "table_control-current_line

UPDATE Y00MOVIES FROM TABLE MOVIE_TAB. "updates database table

ENDCASE.

ENDMODULE.

***********************************************************************************************************************

Hope this solves your problem.
