HCP Trial - PAL: AFL Error [423] when creating wrapper

Hi,

i am following Single Exponential Smoothing - SAP HANA Predictive Analysis Library (PAL) - SAP Library in the HCP Trial.

I replaced

CALL SYS.AFLLANG_WRAPPER_PROCEDURE_DROP('DM_PAL', 'SINGLESMOOTH_TEST_PROC');
CALL SYS.AFLLANG_WRAPPER_PROCEDURE_CREATE('AFLPAL', 'SINGLESMOOTH', 'DM_PAL', 'SINGLESMOOTH_TEST_PROC',PAL_SINGLESMOOTH_PDATA_TBL);

with

CALL "HCP"."HCP_AFL_WRAPPER_ERASER"('SINGLESMOOTH_TEST_PROC');

CALL "HCP"."HCP_AFL_WRAPPER_GENERATOR"('SINGLESMOOTH','AFLPAL','SINGLESMOOTH_TEST_PROC',PAL_SINGLESMOOTH_PDATA_TBL);

because of the HCP Trial limitations.

Now i am getting this error:

Could not execute 'CALL ...' in 151 ms 602 µs .

SAP DBTech JDBC: [423]: AFL error:  [423] "HCP"."HCP_AFL_WRAPPER_GENERATOR": line 31 col 5 (at pos 1742): [423] (range 3) AFL error exception: AFL error:  [423] "PSADBA"."AFL_WRAPPER_GENERATOR": line 57 col 5 (at pos 1842): [423] (range 3) AFL error exception: AFL error: registration finished with errors, see indexserver trace

when calling the wrapper like in the example above.

The rest of the code is still like in the example in the link.

How can i get rid of this error?

Thank you in advance,

Julian
