In BW it is possible to register the AFL & PAL Functions for use within a BW-type called 'HANA Analysis Process' by providing the schema and the procedure (pls see screenshot below).
In what schema can I find the the PAL functions???
I assume they are procedures, right?
I have installed PAL successfully (checked tables SYS.AFL_PACKAGES_ & SYS.AFL_FUNCTIONS_ for the required function 'BINNING' which appears as expected).
