I created another company(B) and installed the COA package already. I exported the COA from the company(B) and updated based on company A customized COA. When I import to the company B, it shows that "The values for the fields 'code, company_id' already exist (they are probably 'Code, Company' in the current model). at multiple rows"

I checked that there is no duplicated code, but I guess the issue is because that I have the same code from Company A. Does anyone know how to figure it out?
