Define Merge Actions for Relationship Database Properties

Use the Database page in the Relationship Properties window to define whether or not to overwrite the Relationship's database properties.

The Relationship Properties window is available in the Relationship Editor (accessed from within the Object Manager in the mApp Editor).

Good to know:

  • You can only configure separate merge actions for individual Relationships and Relationship properties if the Business Object is set to Merge in the Business Object Properties window (mApp page). If the Business Object is set to any other option, or if Include in mApp is unchecked, then you cannot configure separate merge actions for individual Relationship properties.
  • Database properties allow you to create and enable foreign keys for the Relationship. Foreign Keys establish and enforce a link between tables in a relational database, and are required by SQL Reporting Services. It is recommended that you do not use foreign keys unless you have a specific need to do so.
  • For more information about defining Relationship database properties, refer to Define Database Properties for a Relationship.
