Sometimes we need to configure the sap server to pop up a message to the users when they logon to the system. Generally, there are two methods to meet this requirement.

1. Go to transaction SM02 – System Messages. You can maintain the system message here. If user refreshes or open the window, the system message will be displayed.
2. But business wants only part of user will receive such messages when user logon, above method doesn’t work very well. Some enhancement needs to be done. Use customer exit ‘SUSR0001’. Below are the detail steps.

SAPLink is a great tool for ABAPer to share the ABAP development objects between programmers. It is quite easy to import and export custom objects.

This open source project is hosted in Google code and this is the project link: http://code.google.com/p/saplink/.

The core SAPLink only support report and class objects. For other objects like scripts, smartforms and function group, you can down load corresponding plug-ins from another project: SAPLink-plugins.

Here is the document about how to install SAPLink and the user manual. https://wiki.sdn.sap.com/wiki/display/ABAP/SAPlink+User+Documentation

There are several ways to find BADIs in the program.

1. Set a beark-point in method ‘CL_EXITHANDLER=>GET_INSTANCE’. Because old BAID technology will always call this method to get the BADI instance.

2. Search string ‘CL_EXITHANDLER=>GET_INSTANCE’ in the program. This drawback of this method is that the program may call another program in the runtime. In this case, you will be able to find the BADI in another program.

This article aims to give a brief introduction about the SAP Enhancement technologies. The standard deliveried sap programs do not always meet the requirement, so enhancment is an very importment part in the ABAP development. SAP provide several technologies to support developer to enhance the standard logic.

1. User exit.

Actually user exit is not part of enhancement technology, as it need us to enter access key to modify it. But sap delivery these user exit form routines in seperate include files and will not overwrite them in the upgrade version. So we can feel free to modify them.
