How to relate a report page to a tabular form?

Question

I have a table called PRODUCT
SQL> desc product
Name                                      Null?    Type
PRODUCTNUMBER                             NOT NULL VARCHAR2(15 CHAR)
PRODUCTDESCRIPTION                                 VARCHAR2(30 CHAR)
LOCATION                                           VARCHAR2(10 CHAR)
WARRANTY                                           NUMBER(4)
PRODUCTSN                                 NOT NULL VARCHAR2(25 CHAR)
STATUS                                             VARCHAR2(20 CHAR)Now I create a view, and based on this view I create a report page
CREATE OR REPLACE VIEW V_PRODUCT_OVERVIEW AS
SELECT PRODUCTNUMBER, PRODUCTDESCRIPTION, LOCATION, WARRANTY, COUNT(PRODUCTSN) QUANTITY
FROM PRODUCT
GROUP BY PRODUCTNUMBER, PRODUCTDESCRIPTION, LOCATION, WARRANTY;For each type of product (identified by PRODUCTNUMBER), there may be many instances (identified by PRODUCTSN). I want to put an edit button beside each record on the report page. After clicking the edit button, it will redirect to a detail page, which is based on the specific PRODUCTNUMBER, where I can add or modify products.
SELECT PRODUCTSN, PRODUCTSTATUS
FROM PRODUCT
WHERE PRODUCTNUMBER = #THE_PRODUCTNUMBER_OF_LAST_PAGE#I don't know how to accomplish this, especially how to relate these two pages, and how to pass the PRODUCTNUMBER from the first page to the second. Any idea is appreciated! Thanks!

Can't run sample appliation. When I run the appliation, login using "demo/#lower_case_workspace_name#", the browser comes with error message:
ORA-06550: line 2, column 8: PLS-00201: identifier 'CUSTOM_AUTH' must be declared ORA-06550: line 2, column 1: PL/SQL: Statement ignored
Error      ERR-10460 Unable to run authentication credential check function.
