Background documentationActivate the Data Model MM

 

Check (or enhance) and activate the MM data model including temporary IDs for internal number handling.

  1. Check whether you can use the data model delivered by SAP for managing your material master data with MDG for material.

    Activate the delivered data model MM in Customizing for Master Data Governance, Central Governance under Start of the navigation path General Settings Next navigation step Data Modeling Next navigation step Edit Data Model End of the navigation path.

    Note Note

    You can select the governance scope at any point after you activate the Data Model. The governance scope determines which fields from the data model can be edited by the Master Data Governance application. Use this customizing activity to narrow the governance scope: Start of the navigation path Master Data Governance, Central Governance Next navigation step General Settings Next navigation step Process Modeling Next navigation step Define Governance Scope End of the navigation path

    By deactivating or reactivating an entity, a relationship, or an attribute you are not changing any dictionary or database object; you are only changing the ability of MDG to edit the chosen object. When you take a field out of governance scope it becomes read-only on the MDG UI and you may wish to remove it.

    You can use the Customizing activity Import BC Set to Reset Governance Scope to set the governance scope to the EHP6 model which contains only identifying and descriptive data.

    End of the note.

    Caution Caution

    When upgrading to MDG 8.0 check that the active and inactive versions of your data models are the same. Changes to the data models, not dependent on business function switches, may occur due to corrections made by SAP. You should check and activate all models after the upgrade to MDG 8.0 is complete. To do this navigate to Start of the navigation path Master Data Governance, Central Governance Next navigation step General Settings Next navigation step Data Modeling Next navigation step Edit Data Model End of the navigation path and activate any data models that have the entry Different in the column Active Version.

    End of the caution.

  2. Assign an internal key.

    To support internal key assignment, run the activity in Customizing for Master Data Governance, Central Governance under Start of the navigation path General Settings Next navigation step Data Modeling Next navigation step Define Prefixes for Internal Key Assignment End of the navigation path.

    Example: If you create new entries with the following values, all temporary IDs are prefixed with $ and an internal sequence number.

    • Data Model: MM

    • Entity Type: MATERIAL

    • Prefix: $

    Note Note

    For MDG for material, authorizations cannot be defined here. Instead, the existing back-end authorizations are reused.

    For more information, see Customizing under Start of the navigation path Logistics – General Next navigation step Material Master Next navigation step Tools Next navigation step Maintain Authorizations and Authorization Profiles End of the navigation path.

    Other customizing activities in data modeling are only relevant for the material domain if your data model needs to be enhanced. For more information, see Enhancement of Master Data Governance Content and Extending the Data Model for Master Data Governance for Material.
