Hi Pradip ,
Call above program once again with New Parameter Id to User "X" , i mean first call to remove all parameter id then again call same but with new parameter id and it's value.
like ...
MOVE ' ' TO I_PAT-PARID . " Parameter ID
MOVE ' ' TO I_PAT-PARVA. " Parameter Value
MOVE ' ' TO I_PAT-PARTEXT. " Shot description
APPEND I_PAT.
CLEAR I_PAT.
CALL FUNCTION 'SUSR_USER_PARAMETERS_PUT'
CALL FUNCTION 'SUSR_USER_BUFFERS_TO_DB'
upto this you remove all parameter id to particular user id .
then now pass with new value parameter id 's.
MOVE 'ABC ' TO I_PAT-PARID . " Parameter ID
MOVE ' XYZ' TO I_PAT-PARVA. " Parameter Value
MOVE 'SAMPLE TEST ' TO I_PAT-PARTEXT. " Shot description
APPEND I_PAT.
CLEAR I_PAT.
CALL FUNCTION 'SUSR_USER_PARAMETERS_PUT'
CALL FUNCTION 'SUSR_USER_BUFFERS_TO_DB'
