In MDM studio, you define where you want to send your data to and who can do so. You can set up companies of these types:
Standard
Set up a standard company for each D365 FO company that you use to exchange master data. A standard company is required for each source and each target company. For each standard company, define the data stewards. A data steward is a user in D365 FO who can send and release master data for the source company and can receive the data for the target company. Note: A target company data steward must have full access rights in the target company and read access rights in the source company.
External
Set up an external company for each external application to which you want to send master data.
If you send the same data in the same way to several companies, you can group these companies in a target group. You are advised to use separate groups for standard companies and external companies. The data stewards, as defined in the standard companies, are also used for a target group.
