No read access to field string MKPF in SLIN

Question

Hi Friends,
while checking my program through extended program check it is giving warning message as "No read access to field string MKPF" in the TABLES statement. How to correct this?

Hi
The system is just only giving warning as if said to you:
- Hey Abaper! You have declared to use the headerline of MKPF, but perhaps you aren't using it. Check your code and if you don't use you delete that declaretion.
So if you don't use MKPF in your program, you can delete the declaretion, if you use it you can do nothing or you put the string "#EC NEEDED at the end of declaretion. If you do it, while checking program through extend program check, the system skips that message and doesn't show you.
We often use header line of dictionary table only to do an existence query, in this case the system can give that warning message.
For example:
TABLES: BKPF.
SELECT SINGLE * FROM BKPF WHERE BUKRS = P_BUKRS
                            AND BELNR = P_BELNR
                            AND GJAHR = P_GJAHR.
IF SY-SUBRC = 0.
  WRITE: 'Hello'.
ENDIF.
So I made a query on bkpf, but after I haven't read or used its headerline, so the system give me that message.
If I write:
SELECT SINGLE BUKRS FROM BKPF INTO P_BUKRS
                          WHERE BUKRS = P_BUKRS
                            AND BELNR = P_BELNR
                            AND GJAHR = P_GJAHR.
IF SY-SUBRC = 0.
  WRITE: 'Hello'.
ENDIF.
I've done the same thing but now I haven't declared to use the headerline BKPF and so the system won't give me that warning message.
