Define Merge Actions for Detailed Field Properties

Use the Properties page in the Field Properties window to define whether or not to overwrite the following property merge areas:

  • Whether the Field is required.
  • Whether the Field is read-only.
  • Values: Default and calculated values, as well as values to set before a Business Object is saved.
  • Options based on lifecycle state: Behaviors and values based on the Business Object's lifecycle state (only applicable if the Business Object has defined lifecycle states).
    The Field Properties window is available in the Business Object Editor (accessed from within the Object Manager in the mApp Editor).

Good to know:

  • You can only configure separate merge actions for individual Business Object Fields and Field properties if the Business Object is set to Merge in the Business Object Properties window (mApp Solutions page). If the Business Object is set to any other option, or if Include in mApp Solution is cleared, then you cannot configure separate merge actions for individual Field properties.
  • For more information about behavior properties, refer to Define Behavior Properties for a Field.

To define merge actions for Field behavior properties:

  1. Add a Business Object to a mApp Solution using the Add Business Object to mApp wizard.
  2. Open the Field Properties window for a Field in the Business Object you just added to the mApp Solution:
    1. In the Object Manager within the mApp Editor, click the Edit Business Object task in the Structure area.

      The Business Object Editor opens, displaying the list of Fields with a mApp Action column to show the merge actions selected for the Fields in the Add Business Object to mApp wizard (either Overwrite or Do Not Overwrite. The mApp Solution Action column is blank for Fields set to Do Not Overwrite). If you set the Business Object to Merge in the Business Object Properties window (mApp page), then the selections made in the Defaults section (Default Behavior for Fields drop-down menu) are also reflected in the mApp Action column.

      Tip: You can also click the Edit Business Object button Business Object Button on the mApp Editor toolbar to open the Business Object Editor.

    2. Click a Field, and then click the Field Properties button.
  3. Set the individual Field to Merge:
    1. Click the mApp page, and then check Include in mApp.
    2. In the Options area, click Import to Target System.
    3. From the If Already Present drop-down menu, select Merge as the merge action for the Field.
  4. Click the Properties page.

    Field Property Merge Areas

  5. Click the mApp button mApp Solution Merge Actions next to each property merge area, and then select a merge action:
    • Do Not Overwrite Rule: Select this option to leave the specific property unchanged in the target system when the mApp Solution is applied.
    • Overwrite Rule: Select this option to overwrite the specific property in the target system when the mApp Solution is applied.

  6. Select OK.

  7. Prepare the mApp Solution for Distribution (File>Prepare mApp for distribution), or save the mApp Solution (File>Save mApp to Disk) to continue making other changes.
