Interface and API in Oracle

Interface and API in Oracle
--==============================================

Interface:- 
--=======================================

User Interface, we have to write codes for validation and
insertion of data’s in Interface tables and then in Oracle
base tables
·         The good is that if there is failure of record, they remain 
        in the table until either fixed or purged.


Supplier Base Tables:- 

AP_SUPPLIERS
AP_SUPPLIER_SITES_ALL
AP_SUPPLIER_CONTACTS 


Supplier Interface Tables:

AP_SUPPLIERS_INT 
AP_SUPPLIER_SITES_INT
AP_SUP_SITE_CONTACT_INT

Supplier Error Interface Table:-

AP_SUPPLIER_INT_REJECTIONS 

Supplier Interface import Programs:-


1.    Supplier Open Interface Import
2.    Supplier Sites Open Interface Import
3.    Supplier Site Contacts Open Interface Import


API:- Application Programming Interface
--=======================================
An API (Application Programming Interface) is inbuilt
program through which data can be transferred to Oracle
base tables directly without writing the program for
validating or inserting in Interface tables.


-- Call the API
  ap_vendor_pub_pkg.create_vendor(p_api_version      => p_api_version,
                                  p_init_msg_list    => p_init_msg_list,
                                  p_commit           => p_commit,
                                  p_validation_level => p_validation_level,
                                  x_return_status    => x_return_status,
                                  x_msg_count        => x_msg_count,
                                  x_msg_data         => x_msg_data,
                                  p_vendor_rec       => lr_vend,
                                  x_vendor_id        => x_vendor_id,
                                  x_party_id         => x_party_id);

  dbms_output.put_line('X_RETURN_STATUS = ' || x_return_status);
  dbms_output.put_line('X_MSG_COUNT = ' || x_msg_count);
  dbms_output.put_line('X_MSG_DATA = ' || x_msg_data);
  dbms_output.put_line('X_VENDOR_ID = ' || x_vendor_id);
  dbms_output.put_line('X_PARTY_ID = ' || x_party_id);


  IF (x_return_status <> FND_API.G_RET_STS_SUCCESS)
  THEN     
    FOR i IN 1..FND_MSG_PUB.COUNT_MSG LOOP
      l_msg := FND_MSG_PUB.get( p_msg_index => i,
                                p_encoded   => FND_API.G_FALSE
                              );   
       dbms_output.put_line('The API call failed with error '||l_msg);
    END LOOP;
  ELSE
    dbms_output.put_line('The API call ended with SUCESSS status');
  END IF;
