Check 1 = 2

[Former Member]

Hi,

Can anyone explain the <b>'1 = 2'</b> which you can find in SAP sources (for example : SAPDBVAV, SAPDBVLV, SAPF011) ?

It looks to me that it is being used as a way of exiting the FORM. For example, in the program SAPF011.

FORM VORTRAG_AUF_GLEICHES_KONTO.

  IF CONTR-EXIST = SPACE.
    MIGTAB-RACCT = EXTR-RACCT.
    MIGTAB-BUKRS = EXTR-BUKRS.
    CASE CONTR-ERROR.
      WHEN 'SKA1'. MIGTAB-TEXT1 = TEXT-007.
      WHEN 'SKB1'. MIGTAB-TEXT1 = TEXT-008.
      WHEN 'T001'. MIGTAB-TEXT1 = TEXT-026.
    ENDCASE.
    COLLECT MIGTAB.
    CHECK 1 = 2.
  ENDIF.

If it goes inside this IF statement, then it will never go any further in the FORM, it will exit at the CHECK 1 = 2.

Not sure why they didn't just use the "EXIT" statement.

maybe the return code is different

[FredericGirod]

It's a not possible equality, so you will stop at this point and exit the form. It's like an EXIT command.

The people who make this code like to play

It's a way to not execute the code of program after the control.

In a routine like FORM you could also write EXIT instead of CHECK 1 = 2 or...... CHECK 'BATMAN' = 'ROBIN'.... eh! eh! eh!

Hi,

I suppose that this CHECK performs always a negative result.

"CHECK with a negative outcome terminates the current loop pass and goes back to the beginning of the loop to start the next pass, if there is one. "

Sometimes it used to make possible searching something (e.g. messages) via <b>where-used</b> list. E.g. there are places where they collect messages into some application log without issueing it by MESSAGE statement, and obviously in that case you cannot find particular message via where-used list. And certainly something like

IF 1 = 2.
  MESSAGE ....
ENDIF.

can help somehow.
