liveCache error exception when calling SYSTEM.AFL_WRAPPER_GENERATOR

Hi all,

I am starting with PAL, and create the types and the signature table

but when I call the AFL_WRAPPER_GENERATOR procedure I get the following error:

Could not execute 'CALL SYSTEM.AFL_WRAPPER_GENERATOR ('PAL_TS_S', 'AFLPAL', 'SINGLESMOOTH', PAL_TS_SIGNATURE)' in 254 ms 967 µs .

SAP DBTech JDBC: [423]: liveCache error:  [423] SYSTEM.AFL_WRAPPER_GENERATOR: line 34 col 1 (at pos 1717): liveCache error exception: liveCache error: registration finished with errors, see indexserver trace

The code I am trying is the following:

SET SCHEMA I301605;

Drop type PAL_T_TS_DATA;

create type PAL_T_TS_DATA as Table (CALENDAR_ID INT, SALES_AMOUNT  DOUBLE);

Drop type PAL_T_TS_PARAMS;

create type PAL_T_TS_PARAMS as table (NAME VARCHAR(60), INTARGS INTEGER, DOUBLEARGS DOUBLE, STRINGARGS VARCHAR(100));

drop type PAL_T_TS_RESULTS;

create type PAL_T_TS_RESULTS AS Table (CALENDAR_ID INT, SALES_AMOUNT DOUBLE);

drop table PAL_TS_SIGNATURE;

create column table PAL_TS_SIGNATURE (ID INTEGER, TYPENAME VARCHAR(100), DIRECTION VARCHAR(100));

insert into PAL_TS_SIGNATURE VALUES (1, 'PAL_T_TS_DATA', 'in');

insert into PAL_TS_SIGNATURE VALUES (2, 'PAL_T_TS_PARAMS', 'in');

insert into PAL_TS_SIGNATURE VALUES (3, 'PAL_T_TS_RESULTS', 'out');

CALL SYSTEM.AFL_WRAPPER_GENERATOR ('PAL_TS_S', 'AFLPAL', 'SINGLESMOOTH', PAL_TS_SIGNATURE);

Does anyone what this error mean and how to solve it?

Thanks and Regards
