Customers who have multiple deployments of Microsoft Dynamics AX 2012 R2 cannot easily share the master or reference data across all deployments. Sharing currently is implemented using table replication which is very fragile and does not completely support data governance scenarios such as single master, multiple master, conflict resolution, and selective synchronization.
Master data management (MDM) was only introduced in Microsoft Dynamics AX 2012 R3. No feature that supports this scenario exists in Microsoft Dynamics AX 2012 R2.
A supported hotfix is available from Microsoft. There is a "Hotfix download available" section at the top of this Knowledge Base article. If you are encountering an issue downloading, installing this hotfix, or have other technical support questions, contact your partner or, if enrolled in a support plan directly with Microsoft, you can contact technical support for Microsoft Dynamics and create a new support request. To do this, visit the following Microsoft website:

https://mbs.microsoft.com/customersource/support/information/SupportInformation/global_support_contacts_eng.htmIn special cases, charges that are ordinarily incurred for support calls may be canceled if a Technical Support Professional for Microsoft Dynamics and related products determines that a specific update will resolve your problem. The usual support costs will apply to any additional support questions and issues that do not qualify for the specific update in question.
MDM feature overview
MDM is a feature of Microsoft Dynamics AX 2012 that lets you synchronize master data records across multiple instances of Dynamics AX 2012. By creating and maintaining a synchronized copy of master data, you can help guarantee the consistency of important information, such as customer and product data, that is shared across Dynamics AX 2012 instances. Master data is stored in a central data store. This central store then synchronizes the data with each Dynamics AX 2012 instance on a defined schedule. MDM uses Microsoft SQL Server Master Data Services (MDS) as the central data store and Dynamics AX 2012 Data Import/Export Framework entities as the subscriber for data synchronization. MDM is preconfigured to support synchronization of customers, vendors, employees, global address book, and product entities. You can also create customizations to support other Data Import/Export entities in MDM. For more information about the detailed feature, go to the following Microsoft TechNet website:
If you have customizations for one or more of the methods or the tables that are affected by this hotfix, you must apply these changes in a test environment before you apply the hotfix in a production environment.

893082 How to install a Microsoft Dynamics AX hotfix
Install KB2956617 to use the feature of MDM
MDM uses Microsoft SQL Server Master Data Services (MDS) as the central data store and Dynamics AX 2012 Data Import/Export Framework entities as the subscriber for data synchronization.
Install KB2988262 to enable the ModifiedBy property in MDM entity tables
Tables that are used in the MDM entities require the ModifiedBy property enabled. There is a separate hotfix that enables this property on tables. Use the following information to install recommended hotfix:
https://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=2988262The ModifiedBy property has to be enabled for all the tables that are used in MDM. This is mandatory. We need this to differentiate the local changes in these tables with the changes coming from the MDM hub.
Another alternative is to manual change the ModifiedBy property on tables. In order to make sure that it works correctly, iterate through the data sources of the change tracking query of a MDM entity (for example, MdmMDMFVendorEntityCTQuery in this case) and enable the ModifiedBy property for each table. Entities that contain tables that do not have the ModifiedBy property enabled will throw the following exception:
The following are the tables that have to be changed for OOB entities:
You must have the following products installed to apply this hotfix:
Microsoft Dynamics AX 2012 R2
SQL Server Enterprise Edition with Master data services and Integration Services
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
