To all that have made changes to the SBO_SP_TransactionNotification Stored Procedure, please be aware the the object-code is now nvarchar(20), [Actually been that since SBO2004, but SAP have made changes that get errors to surface].
Problem is that Addons using User Defined Objects can't save their data in SBO2007 and later versions of 2005 if there are incorrect code in the SBO_SP_TransactionNotification (Not taking care of that the code might be alphanumeric)
Here is a PDF describing the problem (written because many people tend to get the error at the moment because of the SAP change):
