ALV automatically insert row in alv grid when pressing custom button

[acetedi]

Hello expert!!

I have a requirement when I press custom button to create new data and insert new rows

this is the first screen.. when i press button create call screen 2 and the logic should get new row automatically

I have tried to create a subroutine for button 'CREATE'

  LOOP AT gs_fieldcatalog INTO gv_fcat.
    gv_fcat-edit = 'X'.
    MODIFY gs_fieldcatalog FROM gv_fcat.
  ENDLOOP.
  CLEAR: gt_drebate.
  DO 100 TIMES.
    APPEND wa_rebate TO gt_rebate.
  ENDDO.

Any help or guide would be grateful

Thank You

Do an ALV refresh.

The problem is i put the wrong screen

i should put subroutine in the screen two

FORM update_database .

  CLEAR: gt_drebate.
  DO 25 TIMES.
    APPEND wa_drebate TO gt_drebate.
  ENDDO.

ENDFORM.

I guess you are experiencing the issue of instantiating several GUI controls (i.e. several ALV grids in your case) in the same container: only the first one is shown, so you think that it doesn't work.

See abap - ALV refresh problem while navigating from user command - Stack Overflow.

Okay. Next time, debug your program before posting the question 😉
