Defining Checkboxes  Locate the document in its SAP Library structure

To define the input field of a parameter as a checkbox, you use the following syntax:

PARAMETERS p ...... AS CHECKBOX ......

Parameter p is created with type c and length 1. In this case, you may not use the additions TYPE and LIKE. Valid values for p are '  ' and 'X'. These values are assigned to the parameter when the user clicks the checkbox on the selection screen.

If you use the TYPE addition to refer to a data type in the ABAP Dictionary of type CHAR and length 1 for which 'X' and '  ' are defined as valid values in the domain, the parameter automatically appears as a checkbox on the selection screen.

Example

REPORT demo_sel_screen_param_checkbox .

PARAMETERS: a AS CHECKBOX,
            b AS CHECKBOX DEFAULT 'X'.

The selection screen looks as follows:

This graphic is explained in the accompanying text

Two checkboxes appear on the left side of the selection screen with the selection text appearing on their right. Checkbox b has the default value of 'X'.
