    what is you actual problem? I thinkthere is a misunderstanding.

    4294 seconds is the maximum which you can trace, and you can't change that.

    4294 000 000 microseconds is 4G microseconds and the maximal number for a Interger 32 bit field.

    However, it usually does not make sense to trace longer SE30 traces. Hundrets of other people can like with

    that, so why should it not be sufficient for you.

    The problem you are talking about is the maximum interval between two GET RUN TIME calls. If this is exceeded when you are using high-accuracy measurement, the system cannot represent the measurement interval in a processor register. Consequently, it returns a false value.

    You can use SET RUN TIME CLOCK RESOLUTION to set the measurement accuracy. The default setting is high accuracy.

    Example

    Runtime measurement for the MOVE statement

    DATA: T1 TYPE I,
    T2 TYPE I,
    TMIN TYPE I.
    
    DATA: F1(4000), F2 LIKE F1.
    
    TMIN = 1000000.
    DO 10 TIMES.
    GET RUN TIME FIELD T1.
    MOVE F1 TO F2.
    GET RUN TIME FIELD T2.
    T2 = T2 - T1.
    IF T2 < tmin =" T2."> Interval...').

    Variant 1

    SET RUN TIME CLOCK RESOLUTION HIGH.

    Effect

    GET RUN TIME uses high accuracy with a short measurement interval to measure the runtime.

    Variant 2

    SET RUN TIME CLOCK RESOLUTION LOW.

    Effect

    GET RUN TIME uses low accuracy with a long measurement interval to measure the runtime.

    Note

    Runtime errors:

    u2022 SET_RUN_TIME_CLOCK_ERROR : After GET RUN TIME, you may no longer use SET RUN TIME CLOCK RESOLUTION.
