When you create the form by SMARTFORMS, system will automatically create the function module for called by ABAP/4. You can get this function module by apply function module "SSF_FUNCTION_MODULE_NAME" and send the form name. This function will return the function name for call SMARTFORMS that you created.

Example

DATA: smf_name TYPE TDSFNAME VALUE ’ZSMARTFORM01’,
      fn_name TYPE RS38L_FNAM.
CALL FUNCTION ’SSF_FUNCTION_MODULE_NAME’
  EXPORTING
    FORMNAME = smf_name
  IMPORTING
    FM_NAME  = fn_name.  

When you want to popup message to confirm action, you can apply function module "POPUP_TO_CONFIRM_WITH_MESSAGE". The function will return:

• ’A’ - Yes
• Others - No or Cancel

Example

CALL FUNCTION ’POPUP_TO_CONFIRM_WITH_MESSAGE’
  EXPORTING
    DIAGNOSETTEXT1    =    ’Do you want save data?’
    TEXTLINE1         =    ’ ’
    TITEL             =    ’Confirm message!’
  IMPORTING
    ANSWER            =    lv_answer.  

• Blank Lines

Example

SELECTION-SCREEN SKIP 3.

• Underlines

Example

SELECTION-SCREEN ULINE.
SELECTION-SCREEN ULINE /1(20).

• Comments

Example

Loop...Where

LOOP AT itab where key = pa1.
  ...
  ...
  ...
ENDLOOP.

Loop...Check

LOOP AT itab.
  CHECK itab-key = pa1.
  ...
  ...
  ...
ENDLOOP.

In above logic, Loop...Where is better than Loop...Check because Loop...Where verifys the specified condition internally.
