Hi ,

User command is used to handle GUI events in SAP.

For example if you want to trigger some event on 'BACK , ENTER, STOP' buttons which are on GUI menu bar. You use AT -USER COMMNAD events.

For more refer link :

[http://help.sap.com/saphelp_nw04/helpdata/en/9f/dba3ae35c111d1829f0000e829fbfe/content.htm]

The use of SET parameter is :

SET PARAMETER:

syntax:

SET PARAMETER ID <pid> FIELD <f>.

it is used to store a value of the field in sap memory and it is identified by parameter id(pid).

GET PARAMETER:

syntax:

GET PARAMETER ID<pid> FIELD <f>.

it is used to get data from memory location pid into the given field f.

Hope this will help you.

SELECTION-SCREEN COMMENT 40(15) lb2.

PARAMETERS : b(10).

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN PUSHBUTTON 10(10) lb3 USER-COMMAND pb1.

SELECTION-SCREEN SKIP.

SELECTION-SCREEN PUSHBUTTON /10(10) lb5 USER-COMMAND pb3.

SELECTION-SCREEN SKIP.

SELECTION-SCREEN PUSHBUTTON /10(10) lb4 USER-COMMAND pb2.

*SELECTION-SCREEN BEGIN OF SCREEN 200 AS WINDOW TITLE T2.

SELECTION-SCREEN BEGIN OF BLOCK b1.

PARAMETERS : ch1 AS CHECKBOX, ch2 AS CHECKBOX, ch3 AS CHECKBOX.

SELECTION-SCREEN END OF BLOCK b1.

SELECTION-SCREEN BEGIN OF BLOCK b2.

PARAMETERS : rb1 RADIOBUTTON GROUP a,

rb2 RADIOBUTTON GROUP a,

rb3 RADIOBUTTON GROUP a.

SELECTION-SCREEN END OF BLOCK b2.

*SELECTION-SCREEN END OF SCREEN 200.

INITIALIZATION.

lb1 = 'ENTER A VALUE'.

lb2 = 'ENTER B VALUE'.

lb3 = 'DISPLAY'.

lb4 = 'EXIT'.

lb5 = 'CALL NEXT'.

AT SELECTION-SCREEN.

CASE sy-ucomm.

WHEN 'PB1'.

LEAVE TO LIST-PROCESSING.

WRITE : a, b.

IF ch1 = 'X'.

LEAVE TO LIST-PROCESSING.

WRITE 'FIRST CHECKBOX IS SELECTED'.

ENDIF.

IF ch2 = 'X'.

WRITE 😕 'SECOND CHECKBOX IS SELECTED'.

ELSEIF rb3 = 'X'.

WRITE 😕 'THIRD RADIOBUTTON'.

ENDIF.

WHEN 'PB2'.

LEAVE PROGRAM.

WHEN 'PB3'.

CALL SELECTION-SCREEN 200.

ENDCASE.

SET parameter :

this is used to pass a value from one report a memory n from there we can use in the same report or the other report..

SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens

Hope this helps u,
