            [STARTING AT col1 lin1
            [ENDING   AT col2 lin2]].


... STARTING AT col1 lin1 [ENDING AT col2 lin2]


This statement calls the dynpro with the dynpro number specified in dynnr. dynnr expects a data object of the type n and the length 4. The call starts a new dynpro sequence, which is embedded into the current dynpro sequence. The dynpro with dynpro number dynnr is the initial dynpro of the dynpro sequence. In a dynpro sequence started by a transaction code, up to 50 other dynpro sequences can be nested.

The called dynpro sequence is ended when one the dynpros branches to the next dynpro with the number 0. The program flow is then continued after CALL SCREEN.

The statement CALL SCREEN accesses the dynpros of the relevant main program of the current program group and these use the global data and dialog modules of the main program. Except when calling a dynpro in an externally called subroutine, the main program usually is the current program. If the specified dynpro does not exist in the main program of the program group, an unhandleable exception is raised.

By default, the screens of all dynpros of the called dynpro sequence are displayed in the current GUI window. Use addition STARTING AT to open a modal dialog window.


... STARTING AT col1 lin1 [ENDING AT col2 lin2]


Use addition STARTING AT to open a new popup level and to display all screens of the called dynpro sequence in a modal dialog window. The upper left corner of the dialog box is determined by the values in col1 and lin1 for column and row. The values refer to the GUI window with popup level 0. The lower right corner is set automatically or use col2 and lin2 can be used to specify it after ENDING AT. col1, lin1, col2, and lin2 expect data objects of the type i. The values of col1, lin1 should be less than col2, lin2, otherwise the behavior will be undefined. The maximum popup level is 9.


  • The called dynpro should not be a selection screen. To call a selection screen, use the statement CALL SELECTION-SCREEN.
  • When nesting dynpro sequences and creating popup levels, it must be noted that a (nested) dynpro sequence has generally already been entered when the program is being executed and that the system itself can also create other dynpro sequences or popup levels (for example, field or input help or messages in dialog windows). For this reason, the maximum values of 50 dynpro sequences or nine popup levels within a program should never be used.
  • If during the processing of a modal dialog window a new dynpro sequence is called, it must be started in another popup level. In this case, the statement CALL SCREEN cannot be used without the addition STARTING AT.
  • When calling a dynpro in a dialog window, specify the window as a modal dialog window in its properties and set an appropriate GUI status beforehand. We recommend that a dynpro sequence in a modal dialog window consists of one dynpro only.
  • If there is an open spool request during the execution of the statement CALL SCREEN, a new spool list level is created. The first list output in the new spool list level creates a new spool request.
