iprocurement non catalog request page customization
The requirement is,
1) to include a new LOV, that contains the inventory items from mtl_system_items
2) Once the user chooses the inventory item, the item description and Category fields which are already available in that OAF page must be populated based on the inventory item.
I created a new LOV from JDev for step1 containing inventory items along with their purchasing categories and moved it to my server.
And using personalization i created a new "Message LOV Input" field with its External LOV property set to the one i created. And created LOV mappings also using personalization for this additional field i created. My results are populated as expected. When i chose the inventory item from my custom field(created through personalization) the description is automatically populated into the standard "Item Description" field. And the Category field(standard field) is populated automatically.
