Hi all,

I just want to know Flow of the following code. I want to know which Perform will execute First and which one is 2nd ?

PERFORM process_files.

IF NOT px_par IS INITIAL.

PERFORM schedule_jobs.

ELSEIF NOT px_seq IS INITIAL.

PERFORM file_split.

ENDIF.

Perform xxx.

Perform yyy

Perform zzz

If we have different No of performs like Above Inner Perform( Perform zzz) will execute first or Perform xxx will execute?

Thanks

Hi Krish

Flow goes in sequential manner.

Perform xxx.

Perform yyy

Perform zzz

In this case first sub-routine xxx , next yyy and lastly zzz are executed.

PERFORM process_files.
IF NOT px_par IS INITIAL.
    PERFORM schedule_jobs.
ELSEIF NOT px_seq IS INITIAL.
    PERFORM file_split.
ENDIF.

In this case first process_files then either of schedule_jobs or file_split will be executed.

Kind Regards

The performs will be executed in the sequence they are called. The first one to be called will be executed first, the second one next and so on..

Hi,

It's not clear what exactly you want. PLz. try to be more specific.

Anyway, if you refer to IF, that 2 performs are executed accordingly with values of IF conditions.

- Both px_par and px_seq are initial => no perform executed

- px_par = initial AND px_seq not => file_split only

- px_par <> initial AND px_seq = initial => schedule_jobs only

- both px_par and px_seq <> initial => schedule_jobs only
