Saving Ztable using Module Pool

Question

hi
I want to save the entries into a Ztable using Module pool programming.. I want the Module Pool Program to work like the SM30 table maintenance...
Right now.. I have 2 module pool screen on the screen... one which displays the entries of Ztable and the other which is an input enabled screen so that I can enter records into it..
When I save the records the Ztable should get updated and when the screen again comes to PBO the enetered records should be displayed in the first table control
Right now I am stuck here
PROCESS BEFORE OUTPUT.
* MODULE STATUS_0001.r45
MODULE FILL_TABLE.
LOOP AT TBL_ZTVM3 into wa_ztvm3 WITH CONTROL TC1 CURSOR TC1-TOP_LINE.
ENDLOOP.
LOOP AT TBL2_ZTVM3 into ztvm3 WITH CONTROL TC2 CURSOR TC2-TOP_LINE.
ENDLOOP.
PROCESS AFTER INPUT.
LOOP AT TBL_ZTVM3.
ENDLOOP.
LOOP AT TBL2_ZTVM3.
ENDLOOP.
MODULE USER_COMMAND_0001.
user command goes like this
*&  Include           YENTRIES_ZTABLE_I01
*&      Module  USER_COMMAND_0001  INPUT
*       text
MODULE USER_COMMAND_0001 INPUT.
CASE SY-ucomm.
when 'SAVE'.
modify tbl2_ztvm3 from wa2_ztvm3 INDEX TC2-CURRENT_LINE.
ENDCASE.
ENDMODULE.                 " USER_COMMAND_0001  INPUT
SO quite a simple code.. but after 1 year I just lost touch with this.. I have defined the Selection Column check rows too for the table control
Can you please help me with this.. I <REMOVED BY MODERATOR>

IN PAI of the Module flow logic
you need to modify the internal table with the modified content.
Like this
PROCESS AFTER INPUT.
  MODULE EXIT AT EXIT-COMMAND.
  MODULE CHECK_PAI.
  LOOP WITH CONTROL TC.
    MODULE MODIFY_DATA.
  ENDLOOP.
IN side the MODIFY_DATA
You need to update the Internal table with the modified content. then your internal table will have the latest Information.
You save the latest information.
