today I want to notice few words about companyid field. What is it's purpose. Initially Acumatica provides two !!!! companyid. 1 and 2. Why two? The first is for some Acumatica internal usage, and then your company will get id 2. Even if you believe that your company deserve to be 1, you'll get 2 or more. It means that first active company will have id 2 or bigger. So, if you have some DAC which should be used by few companies, then you just add companyid field, make it as key, and that's it, Acumatica will track to which company your entity should belong.
