sap PAL algorithm - LLANG

I am trying to code a PAL function .

; # create type for kmeans result

ALTER SESSION SET CURRENT_SCHEMA = "CHAVADJO";

DROPTYPE T_KMEANS_RESULT_ASSIGN_TAB;

CREATETYPE T_KMEANS_RESULT_ASSIGN_TAB ASTABLE(

"ID" INT,

"CENTER_ASSIGN" INT,

"ENERGY"DOUBLE);

; # create type for double arguments

DROPTYPE T_SINGLE_COLUMN_DOUBLE_TAB ;

CREATETYPE T_SINGLE_COLUMN_DOUBLE_TAB ASTABLE("VALUE"DOUBLE) ;

; # create type for integer arguments

DROPTYPE T_SINGLE_COLUMN_INT_TAB ;

CREATETYPE T_SINGLE_COLUMN_INT_TAB ASTABLE("VALUE" INT) ;

DROPTYPE KMEANS_DOUBLE_INPUT;

CREATETYPE KMEANS_DOUBLE_INPUT ASTABLE(

"ID" INT,

"V000"DOUBLE, "V001"DOUBLE,

primarykey("ID"));

DROPTABLE #CONTROL_TAB;

CREATELOCALTEMPORARYCOLUMNTABLE #CONTROL_TAB (

"Name"VARCHAR (50),

"intArgs"INTEGER,

"doubleArgs"DOUBLE,

"stringArgs"VARCHAR (100));

DROPTYPE CONTROL_T;

CREATETYPE CONTROL_T ASTABLE ( "Name"VARCHAR (50),"intArgs"INTEGER, "doubleArgs"DOUBLE,"stringArgs"VARCHAR (100));

CREATETYPE PAL_T_KM_CENTERS ASTABLE (CENTER_ID INTEGER, LIFESPEND DOUBLE, NEWSPEND DOUBLE, INCOME DOUBLE, LOYALTY DOUBLE);

DROPPROCEDURE KMEANS_WITH_NEWDB;

CREATEPROCEDURE

KMEANS_WITH_NEWDB

(IN dataset KMEANS_DOUBLE_INPUT,

IN control CONTROL_T,

OUT cluster_assignment T_KMEANS_RESULT_ASSIGN_TAB,

OUT centers PAL_T_KM_CENTERS)

LANGUAGELLANGAS

BEGIN

export Void main(

Table<Int32 "ID",Double"V000", Double"V001"> "dataset" datasetTab,

Table<String "Name", Int32 "intArgs", Double"doubleArgs", String "stringArgs"> "control" argsTab,

Table<Int32 "ID", Int32 "CENTER_ASSIGN", Double"ENERGY">"cluster_assignment"  resultTab,

Table<Int32 "ID", Double"LIFESPEND",Double"NEWSPEND", Double"INCOME", Double"LOYALTY"> "centers" rCEMTab

)

{

pal::kmeans(datasetTab, argsTab, resultTab,rCEMTab);

}

END;

But the issue I get is , please check

Could not execute 'CREATE PROCEDURE KMEANS_WITH_NEWDB (IN dataset KMEANS_DOUBLE_INPUT, IN control CONTROL_T, OUT ...' in 245 ms 286 µs . SAP DBTech JDBC: [2048]: column store error: [34011] failed to save calculation scenario : The following errors occured: Inconsistent calculation model (34011)
