CALL FUNCTION 'Z_CHECK_EXIT' ?

Former Member · ‎2006 Dec 26

How can I use CALL FUNCTION 'Z_CHECK_EXIT' for checking two conditions :

1) The enhancement is to be triggered while creation(va01)/change(va02) of sales orders for Africa fleet card sales only.So check whether va01 or va02.

2) Check whether the sales order type is one from ZSDS,ZSDR,ZSCD and ZSCR.

Source code for the function module:

FUNCTION Z_CHECK_EXIT.

read table xza01 with key ZZUSEREXIT = USEREXIT

CK1 = CK1

CK2 = CK2

CK3 = CK3

CK4 = CK4

CK5 = CK5.

SELECT SINGLE * FROM ZA01 WHERE ZZUSEREXIT = USEREXIT AND

Determine if execution restricted to a single userid

IF xzA01-UNAME IS INITIAL OR xZA01-UNAME = SYST-UNAME.

EXECUTE = 'X'.

I_ZA01 = xZA01.

APPEND I_ZA01.
