When we were working on Performance Appraisal, Customer asked whether Auto Save is possible as the Appraisal document has lot of things to enter. After entering certain things, if user leaves and goes away, system gives time out error. When we explore, we found UI element TimedTrigger element which can used for the purpose.
UI element TimedTrigger automatically and periodically triggers an event with a specified delay.

Sample program

• Create one Web Dynpro component(ZTST_TIMED_TRIGGER).

• Go to view
• Context. Create one node IT_EMP_DATA and attributes in the nodes as shown.

• Place transparent Container and place input fields and bind with attributes of node IT_EMP_DATA.

• Place button for SAVE and create action event SAVE_DATA.

• Code under SAVE_DATA

METHOD ONACTIONSAVE_DATA .

 WD_THIS->SAVE( ).

  ENDIF.

ENDMETHOD.

• Place TimedTrigger element.

•  (1) Set delay here. IF we set Delay 30 means system will trigger action(2) after 30 seconds

• Create Web Dynpro Application

• Run Application and enter data but do not save.

• TimedTrigger triggers event SAVE_DATA after Delay we set to 30 seconds.
