Напомните пожалуйста как маркировать в абап коде фрагмент для изменерения времени выполнения. Когда то давно это делал, фм какой, вроде там тайм штамп участвует.
Предложения в виде
t1 = sy-uzeit.
...
t2 = sy-uzeit.
delta = t2 - t1.
не годятся.

GET TIME STAMP FIELD <f>.

Returns the short or long form of the current date and time, depending on whether the variable <f> has the type P(8) or P(11). The long form returns the time correct to seven decimal places.

GET RUN TIME FIELD rtime.

Effect
At the first execution of GET RUN TIME after the creation of an internal mode, the value 0 is placed into the variable rtime. At each further execution in the same internal mode, the program runtime that has elapsed since the first execution, in seconds, is placed into the variable rtime. The return value of the statement is of the data type i.

Notes
To measure the runtime of program sections, a GET RUN TIME statement can be executed before and after the required section and then the difference of the results can be created. The sequence of statements set within limits is called measuring section, and the time duration determined for it is caled measuring interval.
