Difference between SELECT-OPTIONS and PARAMETERS

Before discussing the differences between SELECT-OPTIONS and PARAMETERS, let’s have a quick introduction of the two.


SELECT-OPTIONS and PARAMETERS are components of the selection screen. SELECT-OPTIONS are assigned a selection table in the ABAP program as well as two input fields along with a push button for multiple selection.  Parameters are assigned a global elementary data object in the ABAP program as well as an input field. The name of the SELECT-OPTIONS and PARAMETERS is limited to a maximum of 8 characters whereas the length of the input field is restricted to a maximum of 255 characters.

SELECT-OPTIONS and PARAMETERS statements are allowed in the global declaration part of executable programs, function groups, and module pools. In function groups and module pools, these statements are only allowed within the definition of a standalone selection screen. In executable programs, these statements are automatically assigned to the standard selection screen.
