The Code Editor is an ActiveX control that can be used to replace the standard source code editor (based on an SAP TextEditor) for any SAP system that supports ActiveX embedding. The reason for the replacement is that the standard RTF control, which the SAP TextEditor is based on, is not optimized for working with line-based text (as source code) and does not support modern code-editing functionality.

ABAP/4 programs can take a very long time to execute, and can make other processes have to wait before executing. Here are some tips to speed up your programs and reduce the load your programs put on the system:

Using this tool can help you know what is effective, under what kinds of conditions. The GET RUN TIME has problems under multiple CPUs, so you should use it to test small pieces of your program, rather than the whole program.
