ABAP Classes and BADIs for HR

Question

Hi all,
Can anyone give me a list of classes SAP has released for HR use by customers and all utility ABAP classes. Also any utility abap classes that would be useful for future. I am only interested in those relevant for ECC 5 and up.
Could you supply the BADIs or Enhancement Spots for HR too.
Thanks
Wayne

The BADI's I have found most useful are the BADI exits that duplicate the existing PA30 PAI / PBO User exits.  If you trace back to where the exits are called you will find the BADI call within a few lines of code - but the difference is that the BADI is called outside one layer of IF logic, so it gets called in some circumstances where the user exits do not - I think this was to do with certain change or copy data situations.
Can't remember the name of the BADI, and do not have a system available to check at present, but it was not hard to find when I looked in the system.
Others I have used are as exits in the HR to FI posting interface, and also some in the travel to vendor interface.  There is also an exit for customising the PERNR search help - cannot remember if this was a class or a FM.
For moving data inside the user exits in a unicode compliant way there are classes for moving data from the flat PRELP character structure to individual infotype structures - CL_HR_PNNNN_TYPE_CAST=>PRELP_TO_PNNNN and CL_HR_PNNNN_TYPE_CAST=>PNNNN_TO_PRELP.
For general unicode compliant constants such as a Tab character there is class CL_ABAP_CHAR_UTILITIES with attributes like CL_ABAP_CHAR_UTILITIES=>HORIZONTAL_TAB.
Also if you go to SE38, select the Blue "Online Help" button, and then go to the ABAP Overview, you will find under the ABAP by Theme branch an entry "ABAP System Classes and Interfaces" which documents 20+ general ABAP classes
Hope this helps
