Hello Odoo community,

I’m encountering an issue while trying to invoice a task in the Odoo Online Field Service module. The error message I receive is:

"Invalid Operation: Cannot create an invoice. No items are available to invoice."

Here’s what I’ve checked so far:

• The task is marked as completed.
• The products/services have been delivered.
• I’ve reviewed the product’s invoicing policy and ensured it's set correctly:
  • For storable products: I’m using "Delivered Quantities" or "Ordered Quantities" as needed.
  • For services: The invoicing policy is set to Prepaid/Fixed Price.
• Additionally, I invoice and pay my employees using two different pay types: Hourly and/or Flat Rate. I want to ensure that this pay structure is being accounted for when invoicing the task.

Despite these settings, I still receive the error when attempting to invoice.

Has anyone encountered a similar issue, or could you provide any suggestions to resolve this?

Thanks in advance for your help!
