Hi,

In the subscreen try LEAVE TO SCREEN 0. this will take you to the calling screen, but if it is possible use SUBMIT and RETURN.

CALL TRANSACTION starts a new external session, where as submit starts an internal session in the current external session.

IF SY-UCOMM = 'IK34'.

call transaction 'IK34'.

ELSEIF SY-UCOMM = 'ZRIK34'.

CALL TRANSACTION 'ZRIK34'.

ENDIF.
