Need help to disable adding more line to Customer Invoice (account.move) using inheritance.
I've tried using these methods;
- Use create=0 on the tree but it disables not only Customer Invoice, but other account.move move_type as well (example: Vendor Bill).
- Tried to put options - no_create = [('move_type') , '=', 'out_invoice)] but it also failed.
Logically, i need to use create=[('move_type') , '=', 'out_invoice)] to solve the method 1 problem but it failed because i think the 'create' attribute is not accepting domain. Any other idea how to disable it?
Thankyou in advance!
