Find Most Used Transaction Codes by User

2 Way To Check It
1.Way                        
              Using Tcode STAD, enter the date, time and length as required. In this example, we are going find based on date 10.07.2015 starting from 00:00:00 for 24 hours length. Meaning here, the logs will calculate for the whole day of 16.09.2015.

What Is The Job Name EU_REORG

                  When starting Transaction SE80 for the first time, the three EU jobs are scheduled automatically: EU_INIT (single start), EU_REORG (periodically each night), and EU_PUT (periodically each night).

EU_REORG:
                       As mentioned above, the indices are automatically updated online by the tools. To keep the effort for updating these indices as low as possible, only the changes are logged, which means a reorganization of the complete index for each program is required from time to time. To avoid having this reorganization interfere with online work, job EU_REORG runs every night and performs this task. If job EU_REORG did not run one night, this simply means that thereorganization takes place more often online.

EU_INIT:
                   EU_INIT serves for completely rebuilding the indices and therefore has a correspondingly long runtime. It starts program SAPRSEUI. All customer-defined programs (selection according to the name ranges) are analyzed, and an index is created that is used in the DW for the where-used lists for function modules, error messages, reports, etc.






How to implement SAP notes?

The Sap Notes can be implemented with SAP Note Assistant. The SAP Note Assistant is called with the sap transaction SNOTE. The SAP Note Assistant is part of the standard system since Basis release 6.10. In earlier releases, you can import it as an additional software component, as an add-on with transaction SAINT. To implement the SAP Note into your system, select the note on the initial screen of the Note Assistant and choose Implement Note.
SAP Notes are implemented with the Note Assistant in the following steps:
 1. You have to localize the required SAP Notes on the SAP Service Marketplace, for example, by searching for keywords or selecting the SAP Note number
 2. You can then load these SAP Notes to the development system with the Sap Note Assistant.
 3. The SAP Notes are checked by the Note Assistant . It checks whether the release named in the SAP Note and the Support Package level is correct, whether the SAP Note requires other SAP Notes before it can be implemented.
 4. The SAP Note is implemented by pressing the import button. This creates a transport request.
 5. The result of implementing the SAP Note is tested in  the development system.
 6. If this test is successful, the transport request is imported to the quality assurance system.
 7. If there are no problem then the transport request is imported to the production system.
The Sap Note Assistant is very important important because:
  •   Automatically implement SAP Notes which handle ABAP source code corrections .
  •   Handle dependencies with other SAP Notes, Support Packages, and modifications
  •   Display all SAP Notes implemented in the system
  •   Correct only a single bug, not a replacement for Support Packages

What is Sap Notes?

            SAP Notes can contain general information, recommendations from SAP or hints and tips. They can also describe a problem and the solution to errors in standard functions of SAP software. This type of SAP Note contains the solution to an individual problem, which is the solution for a programming error, which are some code lines correction.



What is SAP Memory Types

The memory management system assigns memory to a work process. The different memory types are:
  • SAP roll area
  • SAP extended memory
  • Private memory
The sequence of allocation depends on the type of work process and the configuration.
Click here know more information, see Allocting Memory for User Contexts (UNIX)
The user context area that allows direct access can be extended as required when the size of the user context increases.
Click here know more information, see User Context

Roll Area
The roll area is used for additional memory (if available) when the extended memory becomes full, as well as for the initial memory assigned to a user context. The limits are set using parameters.
Extended Memory
The large part of the user context is stored in the extended memory (EM). Page management of this memory stack is performed directly by the SAP system, and not by the operating system. This extended memory is implemented as an unnamed mapped file (on AIX and optionally on HP-UX as shared memory). This means the address space uses the paging file or uses the swap space of the operating system as background memory. For more information, please see the platform-specific documentation.
When the context is changed, the user context, which is in the extended memory, is not copied as with the roll area. Instead it is allocated to alternating work processes by mapping operations. The roll area can be decreased, which results in a faster context change because less data is copied and mapping an extended area is not work-intensive.
All internal tables and ABAP variables are located completely in the area of a user context that can be directly addressed. Copying and input/output operations when accessing internal tables and lists is no longer needed. The result is low CPU usage and shorter access times.
Private Memory
If the extended memory is fully occupied, or the limit for the work process has been exceeded, the work process allocates heap memory. This is known as private memory because it is specific to the process, and the user context can no longer be processed by a different work process (PRIV mode).
