Create a Frontend with SAP Fiori Elements and Annotations
Intro The smart table is a wrapper around existing tables, and can be used together with the responsive tablegrid tableanalytical tableor tree table. The smart table creates columns automatically based on the underlying OData service plus corresponding annotations. Therefore, the main purpose of the smart table is to reduce development effort.
However, this comes at the expense of decreased flexibility. The table toolbar uses the overflow mechanism for adapting to the screen width. Using the responsive table. The smart table offers generic responsive behavior sap. SmartTable, property: demandPopin, value: true :. Using the grid tableanalytical tableor tree table. The title bar contains the title of the smart table, the item count, variant managementand the toolbar itself.
All of these elements are optional. The table area shows the corresponding table responsive tablegrid tableanalytical tableor tree table. The title bar consists of a toolbar. This can be the standard toolbar or a custom toolbar. The standard toolbar can contain a title text with or without item count, variant managementview switch switching the table to edit modean entry point for the P13n dialogand an Export to Spreadsheet action.
The application works fine, but I want to add following validations. I want to have a greater than zero value when user saving records through the List report application. Can I do it using UI5 annotations?
In the application when trying to create duplicate record application navigates to an error page indicating error occurred. How can I validate duplicate records based on the key fields and give warning or error to customer when creating a new record?
The building blocks for doing this are in place, but I can't confirm how much of it will be handled properly by the framework yet:. The sap. ApplicationController has a method executeSideEffects.
With those building blocks, one should theoretically be able to achieve both of your requirements. To anyone who is trying to do validations using annotations, I did not find a way to do the validations using annotations, in a consumption view when writing data. Learn more.

As you can see a data record has a complex property of type my. I want the two properties to appear in the Smart Table as separate columns to be able to filter them. I would also change to a normal sap. Table if it's easier. I have chosen the Smart Table because of it's sorting, filtering, grouping abilities and the variant management I need all of those.
I have searched for a solution for a while, but I haven't found a satisfactory solution matching my entity structure above. My list gives an overview over a specific record set an navigates to a detail page. In my overview list I don't need every property, so I have created a new entity RecordOverview to run my Smart Table against.

Smart Filter Bar Annotations
Triage needs to be fixed urgently, and users need to be notified upon…. Dark Mode Beta - help us root out low-contrast and un-converted bits. Linked 1.As a format and protocol, OData has many features. OData already comes with the concept of metadata, in the form of the metadata document.
However, that information can be enriched through the addition of annotations, which can be managed in layers. Annotations allow you to define additional characteristics that have meaning beyond the basic technical aspects in the metadata document:. Metadata annotations can be provided in different ways: directly within the entity type definitions, outside of the entity type definitions but still within a metadata document, or separate to the metadata document entirely.
Open the following URL:. Find the definition of the Supplier entity type, and look at the attributes in the XML. These are basic annotations that are already part of the metadata document, built directly into this entity type definition. Rather than being directly embedded within the entity type definition, these annotations are separately defined, but are still within the metadata document.
In the next step in the wizard, Data Connectionyou get to specify an OData service upon which the app is to be based. It can then present the available OData services in a list for you to select from.
This time, select the Suppliers entity set, and in the entity set details shown, notice the Annotations tab that shows which data processing operations are supported. In the next step, Annotation Selectionthe wizard queries the catalog service for the chosen OData service to see if any external annotations exist.
This is done in the Template Customization step of the wizard. To keep things simple, just choose the Suppliers entity set for the main mandatory OData collection and leave the other fields as they are. You can run the app immediately, by using the context menu on the new SupplierData project in your workspace:.
Once the app is displayed, selecting the Go button reveals empty lines of data, showing that there are not enough annotations to properly drive this app. Have a look for yourself by expanding the folders within the SupplierData project in your workspace. Leave the values for the fields in the wizard as they are, and follow the wizard through to completion.
In other words, this will be an external set of annotations to enhance the metadata of the OData service. Open up the annotation0.
Use the plus symbol on the right to add a local annotation, specifically the LineItem annotation from the UI vocabulary:. Now create a node within the UI.Background: As of guideline release 1. These guidelines also apply for implementations using smart controls. For example, the OData service determines whether a field is visible on the filter bar, and whether it supports type-ahead and value help.
The smart filter bar analyzes and interprets the metadata provided by the OData service. Default is the design with the toolbar. Note: Changing this value after the SmartFilterBar is initialized initialize event was fired has no effect. This must only be enabled for entities that support such search behavior.

The live mode only operates on non-phone scenarios. Default value is string. Default value is true. ControlType The SmartFilterBar calculates which kind of control will be used for a filter field, based on multiple OData attributes and annotations.
Default value is auto. FilterType The filter type specifies whether the filter field is for a single value, multiple values, or an interval. Default value is Changes at runtime will be ignored. The width can be set only once during initialization. Changes at runtime will not be reflected. Dynamic Selection by default. Default value is false. Implementation should derive from sap. The index can be used to specify the order of groups.
Default value is undefined. Want to dive deeper? Follow the links below to find out more about related controls, the SAPUI5 implementation, and the visual design. This guideline was written for release 1. Use the smart filter bar if:. An OData service is available. You want to develop quickly and efficiently. Do not use the smart filter bar if:. You need to make extensive changes to the filter bar.
Expanded Filter Bar. Smart filter bar - Properties for the expanded filter bar. Defines whether the filter bar includes a basic search. By default, the basic search is not included. Defines whether a property is available as a filter criterion. Defines the filter field as a mandatory filter.
Contains annotations that provide information for rendering a value help list that has been set for a property.Fiori Elements are becoming increasingly popular. Instead of generating a whole application, developers can also use Smart Controls for their existing apps, to add tables, forms, etc.
These controls use annotations that add semantics and structures to the data, provided by the user.
The first screen of our demo app shows a table SmartTable with a list of customers. By selecting a customer, there will be a navigation to the detail page, where customer data can be edited in a form SmartForm. The Entity-Type Customer within our metadata.
We use SmartFields for displaying the values. This control can be used as standalone, for example in XML views:. However… as these annotations are static, in certain cases it might be necessary to provide a dynamic functionality for some fields.
For example: Some customers should have a Street and a City field as well. For others, these two values should even be updatable. It is impossible to express this up-front via metadata annotations. In that case, the annotation sap:field-control can help! Furthermore, we need the properties Street and City.
As our application is running with mockdata, we are using the following json-file to illustrate the different data for each Customer :. However, these values are invisible for CustomerA. The SmartControl is a wrapper for other controls. It interprets OData metadata to determine the control that has to be instantiated. Would you like to access Full Article? Introduction Fiori Elements are becoming increasingly popular. Dynamic Field Control So far, so easy! We adjust the metadata.
User Rating: Be the first one!In this post I want to give an insight into metadata based UI development. I will showcase some of the Smart component features controlled by metadata annotations. With the use of annotations and Smart components like SmartTable you can minimize the UI View code to be written for conventional scenarios like listing and filtering data. To select columns for smartTable, use LineItem annotation. It applies to EntityTypes, and it is a collection of data fields for representation in a table or list: for documentations see Appendix1: Annotationson how to add annotations see Appendix2: Adding annotations to metadata.
Data fields are value paths pointing to properties of our entityType, navigationProperties can be used as path too. By default, the framework recognizes CategoryID type as described in the metadata model: Int Pressing Value Help icon displays value help popup where filter conditions can be defined for CategoryID as Int32 number: equal to, between, less than, ….
To list an entitySet as possible values for a property, use ValueList annotation. It applies to property or parameter, and specifies how to get a list of acceptable values for such property or parameter: for documentations see Appendix1: Annotationson how to add annotations see Appendix2: Adding annotations to metadata.
The list of allowed values is provided as a separate entity set that can be found by interpreting the V4-style annotation Common. ValueList on the same property. To display a human readable text value instead of ID, a reference can be defined for entityType properties.
Notice that this is just a display option, in the background CategoryID property will be sent to server not the Name property when filtering Products, which is the desired behaviour. Example: edm:Property.
Can be placed into the same metadata. In the UI client, the server side metadata descriptor can be extended with OData 4. Annotation file then needs to be referenced in manifest:. Annotation file and the reference to the OData service in manifest will be created:. CDS Annotations. With the use of Smart components UI behaviour can be controlled by metadata annotations without modifing the UI View code. We saw examples of smart features, and ways to extend metadata with annotations.
