I've created a multi-company setup with 1 parent and 2 child companies. The POS on the parent works normally and I am able to close and validate a session. However, When I create a POS for the child companies, when I try to close the session I get the error "Cannot create moves for other companies". I have separate Chart of Accounts for each company. I have traced back the error and have managed to determine the following:

move.company_id.id = 5

x.company_id.id = 1

I cannot understand why x.company_id.id is always 1

Please assist.
