User Parameters

[Former Member]

I have an abap code in a user exit that is working fine. In order though not to have a long coding and not have to correct the coding every now and then, I would like to use the user parameter (SPA) that is stored for every user to have the same outcome in terms of checking. Can anyone help me what to correct in my abap code to use the user parameter SPA

IF sy-uname = 'xxx'

AND ( sy-tcode = 'VA22'

OR sy-tcode = 'VA23' ).

DATA: BEGIN OF i_vbak OCCURS 0,

vbeln LIKE vbak-vbeln,

spart LIKE vbak-spart.

DATA: END OF i_vbak.

SELECT * FROM VBAK

INTO CORRESPONDING FIELDS OF TABLE i_vbak

WHERE vbeln = vbak-vbeln

AND spart = vbak-spart.

LOOP AT i_vbak where spart = '20'.

Flag = 'X'.

endloop.

if flag NE 'X'.

MESSAGE ID 'ZSD' TYPE 'E' NUMBER '997'.

ENDIF.

ENDIF.
