Subinventory Transfer integration within projects not working

Summary:

Hi Team,

This is Oracle fusion Inventory Management. We are doing subinventory transfer under same projects. From the UI it is working, but the integration is picking from the common stock instead of project stock. For intial testing there were stocks created under common but ideally the business will use project stock only in all transactions. The subinventory transfer from source to destination within same project and task is not working from API.
