Hi, I am having trouble with the automation within Odoo.

I am trying to use the source field (record.origin (char) - it  value to reference a many2one relation which references the sales order to populate sales info on our manufacturing order.

I can update a record by a pythonic expression to another studio field (char), but I cannot use the same information to update a many2one as the data types are different (both have identical alpha-numeric entries).

How can I use the automation to essentially "copy and paste" the contents of record.origin to the many2one relationship automatically - both values are in the production model?
