ATG | Persist price information for incomplete orders

By default ATG won't persists price information for incomplete orders. If you print incomplete order from dyn/admin, you won't get price information.

Incomplete Order without price information :

------ Printing item with id: o120001 

<add-item item-descriptor="order" id="o120001">

</add-item>

=========================================================================

To achieve this update orderStateSaveModes (Order state to save mode mapping) property of /atg/commerce/order/processor/SavePriceInfoObjects/ processor [add mapping for INCOMPLETE order].

Example Mapping :

INCOMPLETE=ALL

The valid save modes are :

• ALL : Saves all PriceInfo types.
• ALL_NO_AUDIT : Saves all PriceInfo types, but does not save audit trail information (pricing adjustments and detailed price info objects).
• ORDER : Saves only the OrderPriceInfo object (not shipping, item, tax).
• ORDER_NO_AUDIT : Saves only the OrderPriceInfo object, with no audit information.
• NONE : Saves no pricing information.

ProcSavePriceInfoObjects also includes a defaultSaveMode to use if the current order state does not have an entry in the orderStateSaveModes map.

Incomplete Order with price information (post above configuration change) :

ATG | Configure Last-Modified Property for repository items

Sometimes we need to persist the information, when a repository item was most recently modified. In ATG there is a way to configure last-modified property for item descriptor. 

Follow below steps to configure last-modified property for a given item-descriptor.

1. The item descriptor must contain a date or timestamp property that stores the last-modified value. This property must be persistent (add column in one of the existing table) and single-valued.

   <property name="lastActivity" data-type="timestamp"/>

2. The item descriptor sets the last-modified-property attribute to the name of the last-modified property (defined in above step).

    <item-descriptor name="customerServiceArticle" last-modified-property="lastActivity">

3. The item descriptor sets the updateLastModified <attribute> (attribute of item descriptor) element to true.

<attribute name="updateLastModified" value="true"/>

Example item descriptor (Only demonstrating last modified property).
==========================================================================
<item-descriptor name="customerServiceArticle" last-modified-property="lastActivity">

    <attribute name="updateLastModified" value="true"/>

    <table name="customer_articles" type="primary">
        <property name="lastActivity" data-type="timestamp"  column-name="last_updated"/>
    </table>

</item-descriptor>
 =========================================================================

Note : This property is automatically (no code required) updated with the current time when the item is added or updated.
