Reference type

Select the type of reference: • Relationship: Select this option to add a single-reference relationship (references-one, owned by, scoped-by, or hierarchical parent). Note: You can use this option when mapping a relationship in the desktop system to one that has been implemented in the same way in the APM Remote application (that is, as a relationship rather than as an attribute) • Attribute: Select this option to add an attribute from an application class. • Interface class: Select this option to refer to another interface class. Only other custom interface classes will be available for selection. You can use this option to include attributes from a related application class (for example, to include requirements for a work order task).

Reference type

The type of reference to use for the object at the end of the relationship. For example, if you are entering the WorkRequest.AssetToWorkOn relationship as a property and you select Base class user key as the reference type, the property will contain the Asset number of the work request’s asset. • Base class user key: A unique name or number used to identify each instance of an object in the base class. Some user keys can be edited by APM users. For example, the user key for an asset is the asset number. • Object ID: A unique object identification number that is assigned and managed by APM. • Universal ID: A unique identification number generated by the system. This number will always be the same in both the desktop and remote databases. Note: This setting is only applicable to Application class properties.

Application attribute

The name of the attribute that you want to include. Only attributes owned by the base class or by a selected related class, are available. You must ensure that the data type of the selected attribute matches the data type of the attribute to which you are matching it in APM Remote. Mismatched data types can cause unpredictable results when operating the APM Remote application, or they can cause the download process to fail. Note: This setting is only applicable to Application attribute properties.

Interface class

Select the interface class to use to map the data members of the child object. The interface class must be used for remote replication, and be part of the CustomerRemoteReplication package.

Property name

The system automatically suggests a property name based on the column name of the selected attribute or relationship. If necessary, you can edit it. Each property name in a class must be unique. A property name must also match the column name for the attribute or relationship as it appears in the object model of the APM Remote system (as opposed to the database column name). The download process uses property names to match the data members in the desktop system with those of APM Remote. When you are adding new properties to an interface class, it is, therefore, important to name them properly for the matching process to work correctly.

User key sequence

If multiple user keys are being used in the interface class, you can set the order by editing the sequence number.

User key

Select this option if this property is a user key for the interface class. If multiple user keys are added, you can set the order by editing the sequence number.

Snapshot type

Select whether you want the property to include the net change in the attribute or the current value of the attribute. This option is relevant for numeric attributes (such as Base currency amount, Currency amount, Duration, or Quantity) and Ref-Many relationships. If you are adding a Ref-Many relationship reference, you can select net change to output what was deleted and what was added to the Ref-Many relationship during the transaction.

Required reference

Required reference is selected by default. It is sometimes deselected for relationships on inbound interface classes in APM if the referenced object (for example, an indicator state) might not exist. This prevents the upload transaction from failing.

Exclude from XML

Prevents the property from being included in the XML document generated from its interface class.
