I have a Custom Object called Opportunity_carset.the related list of Opportunity Carset Object is Service.
The Opportunity Carse Object has two fields.
- Model
Version
The Service object has some Picklist Field called
CodeLabelModel and Version values from "Opportunity Carset" are sent as parameter to webservice class to retrieve the "service" Object Custom Picklist values.
My scenario:
Whenever am creating the "Service" record by clicking "New Service" from realted list of "Opportunity carset" Object,the Custom Picklist values should be displayed in Service Object.
Here,
I have created a apex class which take the Model and Version values and will give the custom Picklist values.

This class will return the Picklist Options.Using MetaDataApi I can update the picklist field values in"Service" object.But this all to be happen while creating a record from Relatedlist.Give me some Idea!!!
