What is the difference between APL and UAFL?

Hi There,

Can someone please tell me the difference between APL and UAFL?

As per my understanding APL stands for Automated Predictive Analysis and these are the set of algorithms which SAP inherited with the acquisition of KXEN and APL is enabled from SP9 onwards.

So what is the difference between APL and UAFL?

Can someone answer this?

Regards,

Arjun
