Compose Model Task Panel

The Compose Model task panel serves as a repository of elements that can be dragged-and-dropped onto the Design board to compose the model workflow. Only those elements applicable to the current level of the model are displayed.

You build your model diagram by dragging the required icon from the Compose Model task panel onto the Design board. Once you have placed certain elements on the board, you can also drag out from their input or output ports and use the context menu to create the required item.

Note Note

If you drag out from a component that includes a large number of fields, the Select Display Fields dialog box may be displayed, to enable you to limit the fields that will be displayed in the form or table at runtime. For more information, see Select Display Fields Dialog Box.

End of the note.

When you create a new model or open an existing one, the Compose Model task panel contains only icons for top-level elements: Package, Page and iView. As you drill down into each element, the display in the task panel changes according to level.

Note also that the collection of elements displayed at iView level may change according to the runtime environment that you select. To display only those model elements available in the selected runtime (deploy) environment, choose Tools Options Compiler tab and check the Mask Unsupported features option.

For more information, see Compose the Model in the SAP NetWeaver Visual Composer Modeler's Guide.

Structure

The following table describes the elements available in the different Compose Model task panels:

Compose Model Elements
Group Name	Element Name	Description	Model Level
Components	iView	A diagram for defining a portal iView.	Top
	Page	A diagram for composing iViews on a portal page.	Top
	Package	A "container" for organizing model elements into a portal package.	Top
Components	Form view	A single form for data entry and selection.	iView
	Table view	A tabular view of data, for display and/or edit.	iView
	Chart view	A range of chart types for displaying data.	iView
	HTML view	A container for displaying an external HTML document.	iView
	Nested iView	An iView within a selected iView.	iView
	Layer	A group of components that are shown or hidden together at runtime.
	Flash view	A Flash component, selected from externally-created Flash objects residing on the Visual Composer server	iView
Connectors	Start	Defines a value to initialize the flow.	iView
	End	Defines the end of the flow.	iView
	Navigate	Defines navigation to a different iView.	iView
	Signal In	Receives parameters from a different iView.	iView
	Signal Out	Sends parameters to another iView.	iView
	Popup Signal	Defines the flow of popup data.	iView
	Timer	Defines the timing of an event.	iView
	User Data	Contains the personal data of the user.	iView
	Data Store	Temporarily stores data from the model for later use.	iView
Operators	Filter	Defines selection criteria for retrieving and displaying data. Note that you can use a dynamic expression to define any field in the model as a filter in the operator.	iView
	Sort	Sorts data according to a specified field.	iView
	Sigma	Aggregates the values of all the records into a single record.	iView
	Upper	Retains only the specified top number of records.	iView
	Lower	Retains only the specified bottom number of records.	iView
	Distinct	Omits records containing duplicate data in the selected fields. Note that the fewer fields checked as distinct, the fewer records are returned.	iView
Additional Operators	Union (Union)	Merges into a new dataset the data of two datasets, and removes duplicates.	iView
	Intersect (Intersection)	Creates a new dataset from data that exists in both of two datasets.	iView
	Subtract (Subtraction)	Creates a new dataset from two datasets by including data that is only in the first dataset but not in the second dataset.	iView
	Group by	Groups a dataset according to the selected operation - such as Min or Count - defined for one or more fields (columns).	iView
	Combine	Combines two datasets into a new dataset, channeled into an input form.	iView
	Switch	Accepts input from multiple sources and channels the data to a single model element.	iView

For examples about using each element, see the Compose the Model section of the SAP NetWeaver Visual Composer Modeler's Guide. For details about each element and its properties, see Configure Element Task Panel.

You can filter the display of elements in the task panel by using the Options (Options) drop-down menu at the top center. The options available in the menu are:

Menu Option	Description
Large Icons	Displays each icon with its label beneath it
Small Icons	Displays icons only
List View	Displays icons in a list, with labels to the right
Details View	Displays icons in a list, with labels and tooltips
Expand All	Displays icons (and labels) of all the groups
Collapse All	Displays only the group names

Integration

Usually, you will use the Find Data Services task panel first, to add the main data services of the model. Afterwards, you will use the Compose Model task panel to add model elements not inserted into the model by dragging out from the data services. See the Developing Business Logic section of the SAP NetWeaver Visual Composer Modeler's Guide for a description of the overall model-creation process.
