I want to add order items grid in the sales section of the admin panel
I am following the below link for the same How to Add a Custom Table to Magento Admin Backend
I am getting the menu as order items in sales => order items but when I click on the order items Link to goes to 404 error page
following is the code in my config.xml file
<config>
<adminhtml>
<menu>
<sales>
<children>
<order_items translate="title">
<title>Order Items</title>
<sort_order>20</sort_order>
<action>adminhtml/order_items/index</action>
</order_items>
</children>
</sales>
</menu>
</adminhtml>
I have added Ikantam_KnowledgeBase.xml file in app/etc/modules folder which contains the following code :
<config>
<modules>
<Ikantam_KnowledgeBase>
<active>true</active>
<codePool>local</codePool>
</Ikantam_KnowledgeBase>
</modules>
i was not able to see the menu until I added this file in the above mentioned location . which was not given in the tutorial .
Now I am able to create the menu but the menu takes me to 404 error page.
The tutorial also mentions adding the following code in the configuration file
<config>
<admin>
<routers>
<adminhtml>
<args>
<modules>
<knowledgebase before="Mage_Adminhtml">Ikantam_KnowledgeBase_Adminhtml</knowledgebase>
</modules>
</args>
</adminhtml>
</routers>
</admin>
when I added the above code to the config.xml files code the order items menu disappeared .
I am very new to Magento ,I have no idea where this code should be added.
Any Help will be Highly Appreciated.
