I have got tipical problem while modifying the user & time through SM30.
Crrated a routine from  V_TVIMF view.
Since my table contains some of the key fields as DEC , I could not populate my ztable from total, instead I;m using to populate only change_by and Change_time from total and vice versa.
So it does change to the SSM30 screen when I click on save but not the database save, means once i go to display mode in the SM30 the changes get refereshed to old values.
Any idea to resolve this issue highly appreciated.
Thanks a lot.

Here is my code.

  DATA BEGIN OF total_s.
          INCLUDE STRUCTURE zds_sheet_trim.
  DATA action.
  DATA mark.

  DATA extract_s LIKE total_s.
  DATA: ls_time      TYPE ttztstmp.
**// Set the change user and change time
  ls_time-date = sy-datum.
  ls_time-time = sy-uzeit.
  LOOP AT total.
    IF <action> = 'U'.
     MOVE total TO total_s.
      total+83 = total_s-change_by.
      total+95 = total_s-change_time.
      READ TABLE extract WITH KEY total.
