PAL - [423]: liveCache error SYSTEM.AFL_WRAPPER_GENERATOR

Dear all,

we would like to use PAL functions. The wrapper procedure has been created and tested successfully by calling it with the SYSTEM user, as described in hana_dev_pal_en document.
But now we see the following error message, by calling:

callSYSTEM.afl_wrapper_generator

Could not execute 'call SYSTEM.afl_wrapper_generator('PAL_ANOMALY_DETECTION', 'AFLPAL', 'ANOMALYDETECTION', PDATA)' in 55 ms 674 µs . SAP DBTech JDBC: [423]: liveCache error:  [423] SYSTEM.AFL_WRAPPER_GENERATOR: line 34 col 1 (at pos 1711): liveCache error exception: liveCache error: registration finished with errors, see indexserver trace

Has had anyone similar problems?

Thanks a lot!

Cheers

Alexander
