New Field at Item Level

Question

Hi Folks,
We are using BOB web shop in our project. we have a requirement of an additional field at Item Level named 'Order Reason'. This will be a drop down with a set of values, client requirement is that this range of values should be easily maintainable as it keeps changing from time to time.
- Can this be achieved with configuration, i actually researched a bit on 'Subject Profile'. But i am not sure whether it can be configured for item level.
- If done with Customization, i want this drop down to be populated on loading of shopping basket. Which BADI or FM should i use during shopping basket loading that can populate this drop down.
Kindly feel free to suggest any alternative approach too.
Thanks for cooperation.
Regards,
Rahul

Hi Rahul,
From the technical point of view to achieve this you need to write new custom RFC where you will fetch the dropdown items for your new field and send this data as a table to your frontend application.
In the frontend application you need to write one java backend object which will call your RFC and fetch
the dropdown list from backend.
You need to write atleast one business object which will hold your data and will make it available to http session.
You need to write one action which will call your backend java object and make the data available to
the order creation jsp.
You need to modify the config.xml file like below
<!--  Customizing the show basket action with Z-Actions  -->
<!-- <action path="/b2b/showbasket" type="com.sap.isa.isacore.action.order.ShowBasketAction">
     <forward name="showbasket" path="/b2b/order.jsp"/>
      </action>-->
<action path="/b2b/showbasket" type="com.sap.isa.isacore.action.order.ShowBasketAction">
        <forward name="showbasket" path="/b2b/Z_getItem.do" />
</action>
<action path="/b2b/Z_getItem" type="com.yourcompany.isa.actions.Z_Zitem">
   <forward name="success" path="/b2b/order.jsp" />
</action>
<!--  End of customization  -->
Than you need to make the changes there in jsp to create a new custom field at item level.
Once you are done with all above you have to send the user selected data back to the backend also.
To save the data to the backend you again have to write one action and make the changes in config.xml
like below
<!-- Edited for item -->
<!-- <action path="/b2b/maintainbasket" type="com.sap.isa.isacore.action.order.MaintainBasketDispatcherAction">-->
<action path="/b2b/maintainbasket"
type="com.youcompany.isa.customBasketDispatchAction.Z_CustomBasketDispatcherAction">
<!-- End of edit-->
To save the data to the backend you can implement "CRM_ISA_BASKET_ITEMS" BADI and can get the data in "CHANGEITEMS_BEFORE_ORDER"
