In the new SAP ABAP editor, it’s sort-of possible to remap the keybindings you use. If you’re a regular Emacs user, you often find yourself pressing the wrong key combination accidentally – for instance C-a to go to the beginning of a line, only to find that the new ABAP editor by default respects the regular windows CUA keybindings – so C-a does a “Select All” as it does in many windows programs.

In a recent SAP CRM 2007 implementation, we had the requirement to hide a view (“partial”) in response to a change in a dropdown value.

This is easily done using javascript code on the client side, and what’s more such a solution to the problem is easy to implement and is not really restricted to SAP CRM 2007 or even SAP web development in general.

A short while back I downloaded and installed the SAP NetWeaver 2004S TestDrive SAP system (running on my Atom! machine at home). This provided me with my own (90-day licensed) basic SAP R/3 system which, according to the documentation, includes both ABAP and Java stacks running on SAP’s own database Max DB.

One of the issues that this system is prone to is that the Max DB log gets full (there is no default log cycling). It is quite a well known issue and is even described on the SAP on Linux: Test Drives – Tips and Tricks FAQ . In my case, I encountered this issue after running an SGEN job to generate all the basis components on the system. I could log into the SAP system, but the GUI froze before anything useful came up. Trying to run stopsap, it hung forever at the checking database step (where it runs R3trans d).

Looking in knldiag, I knew I had a full log problem because of this message:
