Naming convention issue while creating CDS views

Hi,

I have a DDL with basic entities header and item , which looks like this .

namespace test_cds_fu1;
@Schema: 'SYSTEM'
context cds_basic_entity {
entity header {
key header_id : Integer ;
item_id_assoc : Association [1..*] to item { item_id};
customer_id : String(10);
base_amount : Integer;
tax_amount : Integer;
};

entity item {
key item_id : Integer ;
key item_desc : String(30);
};

};

I want to create a view on item entity in another DDL file . It looks like this

namespace test_cds_fu1;

@Schema: 'SYSTEM'

view cds_basic_entity_v as select from test_cds_fu1.cds_basic_entity.item

{

  h_id.header_id ,

  h_id.customer_id , 

  h_id.base_amount ,

  h_id.tax_amount,

  h_id.base_amount + h_id.tax_amount as gross_amount,

   item_id ,

   item_desc

};

But, on activation , it says cannot find artifact test_cds_fu1 . Could you please let me know what is right path name for the item entity ?

Thanks!

Anitha .
