Calling PAL procedures from *.hdbprocedures ?

Hello,

I try to generate a PAL procedure from a *.hdbprocedure. It gives me an error when executing:

Could not execute 'CALL "KEMPFS"."test.silvanas_project.test_pal::CREATE_PAL_KMEANS_PROCEDURE"' in 54 ms 337 µs .

SAP DBTech JDBC: [423]: AFL error:  [423] "KEMPFS"."test.silvanas_project.test_pal::CREATE_PAL_KMEANS_PROCEDURE": line 29 col 1 (at pos 1146): [423] (range 3) AFL error exception: AFL error:  [423] "SYSTEM"."AFL_WRAPPER_GENERATOR": line 58 col 5 (at pos 1793): [423] (range 3) AFL error exception: AFL error: registration finished with errors, see indexserver trace

I assume the <signature table> is not correctly filled.

I created *.hdbtable objects, e.g. test.silvanas_project.test_pal::PAL_CONTROL_TBL in schema KEMPFS

I filled the <signature table> this way:

INSERT INTO "KEMPFS"."test.silvanas_project.test_pal::PAL_KMEANS_PDATA_TBL"

  VALUES (1, 'KEMPFS.test.silvanas_project.test_pal::PAL_KMEANS_DATA_TBL', 'in');

Does anybody have an idea? Is it possible to use *.hdbprocedure, where I can not create local types?

Thanks and regards,

Silvana
