Hi alka ritu  ,
Check the following websites for good documentation o n pf status and user-command

1. How to set pf-status
set pf-status ‘ZZBILSTA’.
2. How to set pf-status excluding/including single menu items
You can exclude menus by using exclude :
set pf-status ‘ZZBILSTA’ excluding ‘PST’.
Note: Can also be used with include instead of exclude
3. How to set pf-status excluding/including several menu items
You have to use an internal table to store the status you wan’t to ex- or include:
DATA:BEGIN OF I_PF_STATUS_TAB OCCURS 10,
FCODE,
END OF I_PF_STATUS_TAB.
FORM SET_PF_STATUS_POSTER.
REFRESH I_PF_STATUS_TAB. MOVE ‘PST’ TO I_PF_STATUS_TAB. APPEND I_PF_STATUS_TAB. MOVE ‘ART’ TO I_PF_STATUS_TAB. APPEND I_PF_STATUS_TAB. SET PF-STATUS ‘ZZBILSTA’ EXCLUDING I_PF_STATUS_TAB.
ENDFORM.
4. Setting PF status to the (SAP) system default
set pf-status ‘BASIC’.
5. How to check for pf-status
AT USER-COMMAND.
CASE SY-UCOMM. WHEN ‘ART’. PERFORM STYR_ARTSKONTI. WHEN ‘PST’. PERFORM STYR_POSTER. WHEN ‘BIL’. PERFORM VIS_BILAG. ENDCASE.
6. Use of SY-PFKEY
You can use the system variable sy-pfkey to retrieve the name of the current pf status
USER-COMMAND:
If the user chooses a function code during list processing that is neither processed by the system, or PICK or PFnn, the system triggers the event AT USER-COMMAND. For this event, you must define your own GUI status for a list. To react to your own function codes in a program, you must define the following event block:
AT USER-COMMAND.
  statements.
In this event block, you can use an IF or CASE structure to differentiate between the function codes. They are available in the system field sy-ucomm. There are further system fields that are filled in list events, such as sy-lsind and sy-pfkey, that allow you to make further case distinctions.
Triggering a List Event from the Program
You can trigger a list event from the program as follows:
SET USER-COMMAND fc.
This statement takes effect after the current list is completed. Before the list is displayed, the event assigned to function code fc is triggered, regardless of the dialog status you are using.
The effect is the same as when the user chooses the function. In other words, predefined list function codes are trapped and processed by the runtime environment, the function codes PICK and PFnn trigger the AT LINE-SELECTION and AT PFnnevents, and user-defined function codes trigger the AT USER-COMMAND event block.
Function code PICK triggers an event only if the cursor is located on a list line.
Using this statement in conjunction with the function codes reserved for system functions, you can call the system functions from the program. For example, you can use SET USER-COMMAND '%SC' to call the Find dialog box directly, or to position the list correctly before it is displayed.
If you use several SET USER-COMMAND statements while creating a list, the system executes only the last one.
Example of AT USER-COMMAND.
REPORT demo_list_at_user_command NO STANDARD PAGE HEADING.
START-OF-SELECTION.
  WRITE: 'Basic List',
       / 'sy-lsind:', sy-lsind.
TOP-OF-PAGE.
  WRITE 'Top-of-Page'.
  ULINE.
TOP-OF-PAGE DURING LINE-SELECTION.
  CASE sy-pfkey.
    WHEN 'TEST'.
      WRITE 'Self-defined GUI for Function Codes'.
      ULINE.
  ENDCASE.
AT LINE-SELECTION.
  SET PF-STATUS 'TEST' EXCLUDING 'PICK'.
  PERFORM out.
  sy-lsind = sy-lsind - 1.
AT USER-COMMAND.
  CASE sy-ucomm.
    WHEN 'FC1'.
      PERFORM out.
      WRITE / 'Button FUN 1 was pressed'.
    WHEN 'FC2'.
      PERFORM out.
      WRITE / 'Button FUN 2 was pressed'.
    WHEN 'FC3'.
      PERFORM out.
      WRITE / 'Button FUN 3 was pressed'.
    WHEN 'FC4'.
      PERFORM out.
      WRITE / 'Button FUN 4 was pressed'.
    WHEN 'FC5'.
      PERFORM out.
      WRITE / 'Button FUN 5 was pressed'.
  ENDCASE.
  sy-lsind = sy-lsind - 1.
FORM out.
  WRITE: 'Secondary List',
       / 'sy-lsind:', sy-lsind,
       / 'sy-pfkey:', sy-pfkey.
ENDFORM.
Example of AT USER-COMMAND.
REPORT demo_list_set_user_command NO STANDARD PAGE HEADING.
START-OF-SELECTION.
  SET USER-COMMAND 'MYCO'.
  WRITE 'Basic List'.
AT USER-COMMAND.
  CASE sy-ucomm.
    WHEN 'MYCO'.
      WRITE 'Secondary List from USER-COMMAND,'.
      WRITE: 'sy-lsind', sy-lsind.
      SET USER-COMMAND 'PF05'.
  ENDCASE.
AT pf05.
  WRITE 'Secondary List from PF05,'.
  WRITE: 'sy-lsind', sy-lsind.
  SET CURSOR LINE 1.
  SET USER-COMMAND 'PICK'.
AT LINE-SELECTION.
  WRITE 'Secondary List from LINE-SELECTION,'.
  WRITE: 'sy-lsind', sy-lsind.
  SET USER-COMMAND '%SC'.
