Hi,

This query is used when some one tries to change payment terms it should display error mesage.

SELECT SINGLE zterm

FROM vbkd

INTO l_zterm

WHERE vbeln EQ vbak-vbeln.

IF sy-subrc = 0.

IF l_zterm NE *vbkd-zterm.

error message

endif.

here i have two doubts

1. what does * represents in *vbkd-vbeln

2.does this query works if you write proper error message.

Hi,

1. This is actually a facility provided in abap syntax.

2. It is usually checked while saving a record.

3. For eg.

If we have one variable

EKKO

and another *EKKO

(They both are same only, with same structure)

(but two different variables)

4. The functional meaning, for usage purpose,

of *EKKO is OLDEKKO.

5. While saving the transaction,

the data is saved only if there is any change

in the values.

IF EKKO <> *EKKO.

*--- SAVE

ELSE.

MESSAGE 'NO DATA CHANGED'

ENDIF.

6. We can aswell use any other variale

eg. oldekko

oekko

myekko

etc,

7. But for business meaning,

R/3 has the facility for *

***************************************

. we can use almost everywhere.

2. just copy paste

report azbc.

*--------------------------
TABLES : T001.
TABLES : *T001.

DATA : ITAB LIKE EKKO.
DATA : *ITAB LIKE EKKO.

DATA : NUM TYPE I.
DATA : *NUM TYPE I.

Hi Shewta,

*vbkd is an alias of vbkd ( another workarea ).

Yes you can write your own error message.

For error msg check txn SE91.

Hope this helps, Erwan
