    • Distinguish consumers for a producer replication set in Instance Data Replication (IDR).

    Before you begin

    Role required: admin

    Procedure

    1. On the producer instance, navigate to Instance Data Replication > Producer Replication Sets:
      • Click New for a new replication set
      • Click on a producer replication set.
    2. Check Discrete to enable discrete mappings for your producer replication set.
      Once you enable discrete mapping, each outbound entry for a replication set has a discrete value column. You can define the mapping of each consumer subscription by setting a discrete value.
    3. Navigate to Outbound Entries tab and click New.
      Options Description
      Source Table Name Select one of the tables on the producer instance to replicate. For example, .NET Application [cmdb_ci_dot_net]
      Discrete Field Choose a reference field that defines the mapping for each consumer subscription. For example, if you choose the Assigned To field in the Incident source table, you can distinguish user assignments for specific consumers.
      [Optional] Filter Within the Filter section, you can use the Add Filter Condition to select filter criteria to control the records in the table that are being replicated.
      For example, you might want to replicate only active records. In that case, select Active in the – choose field – list, Is in the – oper – list, and True in the – value – list. If you do not use a filter, all the fields in the producer replication set table appear in the Available column.
      Note:
      The Available column contains the fields in the Source Table that you specified. That table may not contain the Active field.
      [Optional] Include Attachments Select this option to replicate files that are associated with the records that are being replicated.
      [Optional] Included Fields In the Included Fields columns, use the arrows to move table fields into the Selected column to replicate them or into the Available column to prevent replicating them.
      Note:
      Some fields, such as SYS ID (Mandatory), must be replicated. Other fields, such as Edge Encrypted and Password1, can't be replicated and do not appear in either column.
    4. Navigate to Discrete Mappings tab, click New, and fill in the form fields.
      Field Description
      Discrete Value This field sets a rule for what displays for the selected consumer instance within the producer replication set. For example, an Assigned To discrete value gives choices from a designated table of a specific user to show assignments.
      Outbound Replication Entry Select an outbound replication entry that you configured with a source table for this producer replication set.
      Replication Subscription Choose the consumer instance that displays the discrete value assignment.
      Note:
      For each consumer that subscribes to a producer replication set with discrete mapping enabled, they must have a discrete value set.
