Dear  Venkatesh,
Here is your problem
parameters: EMPLOGIN TYPE ZFIR_PASS-EMPLOGIN,
PASSWORD TYPE ZFIR_PASS-PASSWORD.
CASE SY-UCOMM.
WHEN 'LOGIN'.
SELECT SINGLE EMPLOGIN
FROM ZFIR_PASS
INTO L_CODE
WHERE EMPLOGIN IN ZFIR_PASS-EMPLOGIN.
+*why are you checking ZFIRPASS-EMPLOGIN?+_
*you should check with value from the screen the login     *entered by the user in the parameter field EMPLOGIN 
IF SY-SUBRC 0.
MESSAGE I000.
ENDIF.
it should be
SELECT SINGLE EMPLOGIN
FROM ZFIR_PASS
INTO L_CODE
WHERE EMPLOGIN =  EMPLOGIN .
IF SY-SUBRC 0.
MESSAGE I000.
ENDIF.
*same problem repeated here ...instead of checking the screen
*password value passed you are checking something else
SELECT SINGLE PASSWORD
FROM ZFIR_PASS INTO L_SUPNAM
WHERE PASSWORD IN ZFIR_PASS-PASSWORD.
IF SY-SUBRC 0.
MESSAGE I000.
ENDIF.
replace it as
SELECT SINGLE PASSWORD
FROM ZFIR_PASS INTO L_SUPNAM
WHERE PASSWORD  = PASSWORD.
IF SY-SUBRC 0.
MESSAGE I000.
ENDIF.
please check and revert and reward if helpful
