ABAP_MODIFICATION_1 Measurement in Parallel Session
You can activate runtime analysis for ten simultaneous external sessions (work processes). This makes it possible to switch into a long-runnng job from outside. You can switch in and out of the work processes that you want to measure using a screen similar to Transaction
ABAP_MODIFICATION_2 Measurement Restrictions
You can restrict the duration of a measurement, the size of the performance data file, and also select the objects that you want to measure.
The duration of the measurement is specified in minutes.
The measurement ends after this time. The maximum duration is
approximately 72 minutes. The size of the performance data file is specified in kilobytes. Once this size is reached, the measurement ends. You can restrict the measurement to specific objects:
Programs and function groups
Global and local classes
Methods, subroutines, or function modules
Particular statements
ABAP_MODIFICATION_3 Aggregation
Aggregation can be divided into
This allows a multiple-level analysis in which the first step is to determine the most runtime-intensive statements. Then, in a second step, you can run a new measurement restricted to these objects.
Some information is missing from the aggregation: There is no hierarchy. Furthermore, you cannot branch to the call location from
ABAP_MODIFICATION_4 Measurement Variants
The default variant is stored under the name
ABAP_MODIFICATION_5 Unique Identification for Internal Tables
The name of an internal table is the internally-unique

ABAP_MODIFICATION_7 Hit Lists
In the hit list of the database tables, the buffering is empty if buffering is switched off or not allowed. As well as the database hit list, there are object-based hit lists for classes, instances, and internal tables. For classes and instances, there is a further division between methods and events.
ABAP_MODIFICATION_8 Use of New Toolss
The various hit lists are created using the

ABAP_MODIFICATION_9 Changes to the User Interface
The user interface of the runtime analysis tool has been fully revised. The new features are represented by four main areas, into which you can branch from the initial screen, namely: Executing the runtime analysis Switching on an external session Setting the measurement restrictions Evaluating the measurement results
