consistencie data check on table control

Question: Hi all
I am making a table control
in my pai, I have the folowing simple code


MODULE UPDATE_100 INPUT.

  modify int_invent index tab_code-current_line.

  ENDMODULE.                 " UPDATE_100  INPUT.

intinvent have a few field, including those 4: min_wip_plant, max_wip_plant, min_wip_sc and max_wip_sc

im trying to check if max > min before the int-table is being modified with modify. It is possible to do so or i must do it in this code instead:

FORM RELMINMAXUPD.

  LOOP AT INT_INVENT.
    MOVE-CORRESPONDING INT_INVENT TO INT_ZRELMINMAX.
    APPEND INT_ZRELMINMAX.
    CLEAR INT_ZRELMINMAX.
  ENDLOOP.


  MODIFY ZRELMINMAX FROM TABLE INT_ZRELMINMAX.

ENDFORM.                    " relminmaxupd

wich is called when ok-code 'save' is pressed. If i do it there and i stop the save cause of wrong data, will update_100 get called again?
update_100 is called in the screen flow logic tc loop but im a bit confused on when its being called. As soon as a user clic/modify the tc?? As soon as any button is pressed??

Thanks, Regards.

Answer:
Hello,

Normally it should work with the if clause around your modify statement in the input PAI.


Best regards,
