How to make an abap program pause?

问题

For testing purposes I need my ABAP program to wait for few seconds. How can this be done?

回答1:

2 solutions:

1) Either use WAIT UP TO ... SECONDS.

WAIT UP TO 42 SECONDS.
WAIT UP TO '0.5' SECONDS.

• Does a roll-out and releases the work process to the listener
• Does an implicit Database commit

Use it when CPU processes are at a premium and when the implicit commit will not corrupt your data or cause a short dump because of an open database cursor.

2) Or use the function module ENQUE_SLEEP:

    CALL FUNCTION 'ENQUE_SLEEP'
      EXPORTING
        seconds = 42.

• Does not release the work process
• Does not cause an implicit Database commit

Use it when you cannot afford an implicit commit, and the system can handle the work process(es) being tied up for the duration of the SLEEP command.

ABAP WAIT UP TO SAP Documentation

WAIT statement has an implicit COMMIT which is something that should be avoided.

Do you really need it to pause? You could trace through it by entering /h into the transaction field before you execute the program or by setting a breakpoint in the code.
