Creating your own SAP Customized Main Menu

You can add additional menu transaction in the SAP main menu without affecting the original SAP default area menu S000.
For example, you have created a transaction code called ( z123 - ABC Own Report ) and you want to insert it under Logistics.  The specific user will be able to access ABC Own Report by clicking Logistics -> ABC Own Report.
Steps :-

• Goto Transaction SE43 - Area Menu
• Click the copy button.  Copy from S000 to ZXXX
• After copying, click Change (area menu ZXXX)
• Double click on Logistics and add in your transaction code in the AreaMenu.
• Remembers to Activate it.
• Next Goto Transaction SU01 - Maintain users
• Type in the user name and click the Defaults button
• Type in the area menu (ZXXX) in the Start Menu field.

• Click Save
• The user will be able to see the additional transaction on the next logon.

The CUA area menus are converted to tree navigation in Release 4.6A. The menu contents are automatically copied into a new data structure in Upgrade to Release 4.6A or higher. You can edit Area Menus with a new maintenance interface (Area Menu maintenance transaction: SE43 ). Reporting Tree Integration - Only transactions could previously be put in Area Menus. From Release 4.6A you can also put all the types of reports which are in reporting trees, in Area Menus. The system automatically assigns a transaction code to call the report from the menu. If you have already put the report in another Area Menu, no new transaction code is generated, the unique transaction code already assigned is used.
You can create Area Menus from complete reporting trees with the migration transaction RTTREE_MIGRATION . The report transaction codes are generated automatically.
Reporting trees can only be displayed. They cannot be maintained. To modify the contents of reporting trees, you must convert them with the migration transaction. You can then modify the contents with the Area Menu maintenance.
