Can you please read this ABAP sentence for me? :-)

Question

Hi,
What does it means the "operator" CHECK in the apap sentence below?
Does the bset-mwskz EQ 'II' or OR bset-mwskz EQ 'N0' should be present in the report or not?
    SELECT * FROM bset WHERE bukrs = bkpf-bukrs
                         AND gjahr = bkpf-gjahr
                         AND belnr = bkpf-belnr
                         AND ( ktosl = 'ESA' OR ktosl = 'VST' ).
      CHECK bset-mwskz EQ 'II' OR bset-mwskz EQ 'N0'.
Thanks and BR

Answer 1

CHECK bset-mwskz EQ 'II' OR bset-mwskz EQ 'N0'
The above check is similar to the below code.
IF bset-mwskz EQ 'II' OR bset-mwskz EQ 'N0'.
   <<code after CHECK statement>>
ELSE.
  <<branching statment>>
ENDIF.
The <<branching statement>> could be
1. CONTINUE if the CHECK is within a LOOP.
2. EXIT if its called within a subroutine or a particular event.
Say for example, if your code is llike this.
SELECT * FROM bset WHERE bukrs = bkpf-bukrs
AND gjahr = bkpf-gjahr
AND belnr = bkpf-belnr
AND ( ktosl = 'ESA' OR ktosl = 'VST' ).
CHECK bset-mwskz EQ 'II' OR bset-mwskz EQ 'N0'.
<<some code>>
ENDSELECT.
Then it is similar to the code below.
SELECT * FROM bset WHERE bukrs = bkpf-bukrs
    AND gjahr = bkpf-gjahr
    AND belnr = bkpf-belnr
    AND ( ktosl = 'ESA' OR ktosl = 'VST' )
    AND ( mwskz EQ 'II' OR mwskz EQ 'N0' ).
<<some code>>
ENDSELECT
Hope this helps.
