Pathch is applied when their are multiples error are their in program

Hi..

Following might be useful to u.

Usually S notes will be given by SAP and u implement using Snote.

The Note Assistant (transaction SNOTE) helps you to implement SAP OSS notes. Although it

is not perfect it does generally make the application of OSS notes a much easier process. Note

assistant is at its best when all that is required is a simple code deletion/insertion into an existing

ABAP object. If the object does not exists then you will be required to do the creation bit manually,

note assistant will then be able to insert the ABAP code.

Another benefit of SAP note assistant is that it automatically prompts you to implement any

prerequisite notes that apply.

Note assistants biggest problem comes when updates have been provided by SAP but not for

general release (i.e. a specific fix for your company) or you have modified standard SAP code. If

note assistant tries to update an object which has been changed using this method then it

may have trouble inserting the code in the correct place.

<b> ABOUT PATCHES</b>

These are like enhancements.

Enhancement points are basically hooks at certain defined points within the ABAP code i.e. at the beginning and end of a FORM. These hooks allow you to attach your own custom code which will be executed as if it had been hard coded into the code using a modification. Unlike hard coded modifications these will not be lost during upgrade or patching exercises.

There are 2 types of enhancements with the enhancement framework:

1. Explicit enhancement points: These are basically hooks already coded into the program by SAP at various points of the code. See program RIAUFMVK for examples of these! These are very easy to implement simply go into enhancement mode of SE80 and right click on the enhancement point where you want to add your code and choose ‘Enhancement Implementation->Create’ Give it a name, description and assign it to a change request (should not be a Z package) and then simply add the code as normal.

2. Implicit enhancement points: These are basically points within ABAP code where an enhancement point is implied, and in which case can be created. Examples of implicit enhancement points are at the beginning and end of FORM’s, at the end of a program, include or function module etc.

Thanks
