Creating invoice from contract in workflow

Hi I’m trying to create invoice when contract status changes to signed in workflow.
The invoice is created but I’m unable to copy prouducts from contract to invoice.
This is my workflow:

What fields I need to set to get products from contract in invoice?

it seems line items are a separate module when looking through workflow

Add action
record type = invoice

Add another
record type = line items

I have not tested this works and creates one invoice with line items inside - just a suggestion :slight_smile:
