1. 在系统对于modification的调整中，reset to original对大部分object都是起作用的，除了BAdI和customer exit这种customer enhancement。这个是不能调整会系统原始状态的。

2. 对于使用了modification assistant的

如果还没有用SPAU进行调整(object前有交通灯icon)，此刻使用reset to original只是将此刻的active版本作为original版本，也就是说object不会被更改，相反，升级中产生的modification会被删除。

如果已经进行了SPAU进行调整，则升级中产生的新的版本会在modification log中记录，此版本被认为是orginal版本，使用reset to original功能，以前的modification会被删除，upgrade过程中的版本会成为当前object.

3. 对于没有使用modification assistant的

不管有没有用SPAU进行调整过，当前的active版本都会被当作original版本使用

4.reset to original使用之后，SE95 SPAU都不会再显示这个Object，而且在以后的升级过程中，也不会再次出现在list中。

Restrict users (sales persons) to view or change Sales order data - Using Enhancement framework:
Source Code Enhancement is one of the enhancement technologies available under Enhancement Framework. Implementing this technology is also called as Source Code Plug-In. Technically the source code plug-in implementations are stored in a separate include program and not as part of the original source program.
There are two types of Source Code enhancements possible.

Implicit enhancement option
• Explicit enhancement option

Example Scenario:
One sales person can’t see or change another sales person’s sales orders.
In my program, I have used following users.
Sales person1 (user 1): lz8xzf
Owner for Sales order no: 174.
Sales person2 (user 2): lzn4rm
Steps to Implement the Implicit enhancement option:
Step1:
Go to SE38 and Open include MV45AFZB
Step2:

In order to implement any of these Source code enhancements, you need to be in
‘change Enhancement mode’ (the spiral icon available in the editor).


Step3: Go to EDIT option in the menu and choose Enhancement Operations -> Show implicit Enhancement Options

All Implicit Enhancement option will be displayed. All yellow lines indicate Implicit Enhancement options. In ABAP programs, implicit enhancement options are predefined at the following places:
•
Begin/End of an include.
•
Begin/End of Method/Function Module/Form Routine
•
End of a structure
•
End of Private/Protected/Public Section of a local class


Step4: Place the cursor on the yellow line and choose
Enhancement implementation à Create.

Step5: Give Implementation name and then create.

Step6: Here Editor will be enabled to write the code. Write your own code save and activate it.

Step 7:
Once the development is completed you can test the scenario.
When Sales person (lzn4rm) tries to Open Sales order no 174, it gives error message ’Access Denied’.

Note: Sales order 174 is created by another sales person (lz8xzf).
