Hi Lisa,

After user enters value in Screen 102, lets say CONTINUE is pressed. In PAI for 102 for OK_CODE 'CONTINUE' use

SET SCREEN 0.
      LEAVE SCREEN.

Your processing will then start from CALL METHOD gcl_tree->add_node

Hi,

In the place, you want to leave screen processing,

Place the code specified above. i.e.

SET SCREEN 0.

LEAVE SCREEN.

Which will take you to Parent screen i.e. the earlier screen.
