Freelancer required for Salesforce development.
1. Shift existing data from Lead object to Lead as well as Opportunity & Product Object. The mapping etc will be provided, script to be written for migration.
2. Trigger to make fields write once read forever.
3. While importing data into a multi-select picklist, we have to first export existing data then append new values to existing values followed by final import. Create a visualforce page to deal with data import so that data can be given directly which by logic can be appended to the multi select field.
