I am a beginner and started creating some mapping using hibernate mapping generator, but started getting an exception

“Foreign Key(batch_job_Dependency)[ID_DEPENDANT_BATCH] must have the same number of columns as the referenced primary key
(Batch_job)[ID_BATCH,ID_BATCH_JOB]”

Could anyone please help me in fixing this problem, I would very much appreciate your help

There are 2 tables

create table “BATCH_JOB_DEPENDENCY”(
“ID_DEPENDANT_BATCH” NUMBER not null,
“ID_DEPENDANT_BATCH_JOB” NUMBER not null,
“ID_BATCH” NUMBER not null,
“ID_BATCH_JOB” NUMBER not null,
constraint “PK_BATCH_JOB_DEPENDENCY” primary key (“ID_DEPENDANT_BATCH”,”ID_DEPENDANT_BATCH_JOB”,”ID_BATCH”,”ID_BATCH_JOB”)
);

alter table “BATCH_JOB_DEPENDENCY”
add constraint “FK_MATCH_JOB_DEPENDENCY_01”
foreign key (“ID_DEPENDANT_BATCH”,”ID_DEPENDANT_BATCH_JOB”)
references “BATCH_JOB”(“ID_BATCH”,”ID_BATCH_JOB”);
alter table “BATCH_JOB_DEPENDENCY”
add constraint “FK_MATCH_JOB_DEPENDENCY_02”
foreign key (“ID_BATCH”,”ID_BATCH_JOB”)
references “BATCH_JOB”(“ID_BATCH”,”ID_BATCH_JOB”);
create unique index “PK_BATCH_JOB_DEPENDENCY” on “BATCH_JOB_DEPENDENCY”(“ID_BATCH”,”ID_BATCH_JOB”,”ID_DEPENDANT_BATCH”,”ID_DEPENDANT_BATCH_JOB”);

create table “BATCH_JOB”(
“ID_BATCH_JOB” NUMBER not null,
“JOB_NAME” VARCHAR2(30) not null,
“JOB_DESCRIPTION” VARCHAR2(200),
“JOB_ORDER” NUMBER not null,
“JOB_STATUS” VARCHAR2(1) default ‘E’ not null,
“ID_BATCH” NUMBER not null,
“JOB_NUMBER” NUMBER not null,
constraint “PK_BATCH_JOB” primary key (“ID_BATCH_JOB”,”ID_BATCH”)
);

alter table “BATCH_JOB”
add constraint “FK_BATCH_JOB_01”
foreign key (“ID_BATCH”)
references “BATCH”(“ID_BATCH”);
create unique index “IX_BATCH_JOB_01” on “BATCH_JOB”(“ID_BATCH”,”ID_BATCH_JOB”);

create table “BATCH”(
“ID_BATCH” NUMBER(8) not null,
“NAME_BATCH” VARCHAR2(40) not null,
“AD_FREQUENCY” VARCHAR2(30),
“CMT” VARCHAR2(2000),
constraint “PK_BATCH” primary key (“ID_BATCH”)
);

create unique index “IX_BATCH_01” on “BATCH”(“ID_BATCH”);

These are the two mappings
