ABAP事务码SAT里的Gross time and net time

以一个简单的例子说明：

REPORT ztest22.
START-OF-SELECTION.
  PERFORM main.
  CALL FUNCTION 'ZTIME_SPENT'
    EXPORTING
      iv_time = 2.
  CALL FUNCTION 'ZTIME_SPENT'
    EXPORTING
      iv_time   = 1
      iv_nested = abap_true.
  WRITE:/ 'finish'.
FORM main.
  WAIT UP TO 1 SECONDS.
ENDFORM.

ZTIME_SPENT的实现:

CHECK iv_time > 0.

WAIT UP TO iv_time SECONDS.

IF iv_nested = abap_true.
   CALL FUNCTION 'ZTIME_SPENT2'
      EXPORTING
         iv_time = iv_time.
ENDIF.

ZTIME_SPENT2的实现:

CHECK iv_time > 0.

WAIT UP TO iv_time SECONDS.

总的gross time: 1 ( subroutine MAIN ) + 2 (ZTIME_SPENT call with iv_nested = abap_false ) + 1 ( time spent on ZTIME_SPENT itself) + 1 ( time spent on ZTIME_SPENT2, since iv_nested = abap_true)

image

第一次ZTIME_SPENT调用，其gross time = net time = 2 seconds 第二次ZTIME_SPENT调用, 其net time = 1 second ( WAIT UP TO 1 second), 其gross time 的另一个1 second是花费在另一个function module call ZTIME_SPENT2 上的，因此不能计算在其net time内。
