Hi,

I am trying to create a PAL procedure of KMEANS and I get this below error:

AFL error: [423] "SYS"."AFLLANG_WRAPPER_PROCEDURE_CREATE": line 156 col 5 (at pos 5073): [423] (range 3) AFL error exception: AFL error: Registration of AFLLANG wrapper procedure "OWNSCHEMA"."PAL_KMEANS_PROC" failed with error 'no matching overload found'

code:

CALL "SYS"."AFLLANG_WRAPPER_PROCEDURE_CREATE"('AFLPAL', 'KMEANS', 'OWNSCHEMA', 'PAL_KMEANS_PROC', "PAL_KMEANS_PDATA_TBL");

I have access to OWNSCHEMA and created the table types and the signature table mentioned in the call statement above.

Please help us to solve this error:'no matching overload found'.

Thanks in advance,

Shilpa.

This may happen due to the incompatible changes between different HANA SPS versions. Please check the appropriate documentation for the version that you are using.

To get the version, execute following sql:

Select * from "SYS"."M_DATABASE";

Then check if that procedure has same or different number of parameters.

Use the example in that particular version of help documentation for:
