          [WITH sel criterion]
          [WITH FREE SELECTIONS freesel]
          [WITH SELECTION-TABLE rspar].

These additions have the following effects:

·        VIA SELECTION-SCREEN

The selection screen of the called executable program appears. If you transfer values to the program using one or more of the other options, the corresponding input fields in the selections screen are filled. The user can change these values. By default, the system does not display a selection screen after SUBMIT.

·        USING SELECTION-SET <var>

This addition tells the system to start the called program with the variant var.

·        WITH sel criterion

Use this addition to fill individual elements sel of the selection screen (selection tables and parameters) with the help of the language elements criterion.

·        WITH FREE SELECTION freesel
User dialog for dynamic selections. To use this option, the called program must be connected to a logical database that supports dynamic selections.

·        WITH SELECTION-TABLE rspar
Dynamic transfer of different values. An internal table rspar with the Dictionary structure RSPARAMS is created. This table can be filled dynamically in the calling program with all the required values for the selection screen of the called program.

For more information on these additions, refer to the keyword documentation.

Except for WITH SELECTION-TABLE, you can use any of the above options several times and in any combination within a SUBMITstatement. In particular, you can use the WITH sel addition several times for one single criterion sel. The only combination possible for the WITH SELECTION-TABLE addition is USING SELECTION-SET.
