Creating Operations for a Mobile Business Object

Use the Operation Creation wizard to create an operation and add it to the mobile business object.

Prerequisites

You must first create a mobile business object before adding an operation, unless you create the mobile business object directly from the data source, in which case you can drag-and-drop the data source on to the Mobile Application Diagram which launches the Quick Create wizard for automatic creation of attributes and operations.

Task

Launch the New Operation wizard from the Mobile Application Diagram by selecting the Operation icon from the palette, then selecting the operation section of the mobile business object to which you are adding the operation.
Follow the wizard instructions to add an operation to the mobile business object. Include the operation type that allows you to Create, Update, or Delete data on the back-end data source, Entity Read used in conjunction with Create and Update to refresh a single instance of an MBO, or Other for other types (or undefined) operations.

Note: The New Operation wizard varies depending on the type of data source to which the operation is bound. See the corresponding binding topic for detailed information.

Select either:

Option	Description
Specify a data source	Specify the data source to which the mobile business object operation maps. You must have access to the data source (for example, a data source connection profile) to which you are binding to use this option.
Bind data source later	Manually define the operation, parameters, and role assignments without binding to the data source.

Mobile Business Object Operation Properties
Modify mobile business object operation properties during operation creation, or later, using the Properties view.
Old Value Argument
Use the Old Value Argument field to map a remote operation argument to a second (old) argument in update or delete operations. Only MBOs bound to JDBC data sources support the Old Value Argument.
Entity Read Operations
Entity Read MBO operations refresh a single instance of an MBO composite graph in the SAP Mobile Server cache for Create and Update operations, and are typically used when the Create or Update operation cannot return the entire graph.
Defining Output Mappings
You can map results returned from a remote operation into an MBO, including mapping multiple results to the MBOs of a composite graph, for example, when configuring Entity Read Operations.
Composite Operations
The MBO designer can model a create, update, or delete operation on the root node of a composite relationship graph that accepts the entire composite graph as input.
Defining Input Mappings
Allows mapping of remote operation arguments to input values, including all nodes of a composite graph.
Multi-level Insert Operations
In a multi-level insert, multiple mobile business objects are synchronized in a single operation. The mobile business objects must have a defined relationship, and the insert parameters must support the relationship.
