SPO via BADI

Hello Experts,

I was going though below post :

http://scn.sap.com/message/13654521

I really need help in getting the technical name (suffix, last 2 characters) of SPO part provider right. I followed the above post but unable to resolve the issue. I want it ending with LC, LA & LN but I get it as 01,02,03.

Can someone help with sample piece of code to get this done ? I also followed http://scn.sap.com/docs/DOC-26583 and directly pasted the ABAP code available in "Class YCL_IM_RSLPO_BADI_PARTITIONING v1.txt.zip" in link http://scn.sap.com/docs/DOC-26583.

Do I need to modify the code available in http://scn.sap.com/docs/DOC-26583 link ?

Regards,

Mihir
