Not able to use HANA Online Scenrios with PAL algorithms

Hi everybody,

I just created a scenario using SAP PA 1.15 and SAP HANA SPS7 Rev 73.

I wasnt able to use HANA Online scenarios except of HANA Apriori. I always get the same error:

Funny thing. I did the same thing in a different landscape. Same PA version, same HANA revision --> Same error message!

Another aspect is that all the R algorithms are working fine!

I created a lot of scenarios using HANA online algorithms a couple of month ago with the old version of PA and HANA SPS6 and it actually worked out find.

Any thoughts, any ideas or same problems?

Regards, Christoph.
