Developing Fiori Apps

Fiori Development

Fiori Elements app creation (List Report, Object Page, Worklist), CDS annotations for UI, value helps, draft-enabled UIs, SAP Fiori Tools usage

Create Fiori Elements applications using CDS annotations, configure List Reports, Object Pages, Worklists, and Overview Pages with proper value helps, field groups, and draft support.

Process

1. Review the task requirements.
2. Apply the skill's methodology.
3. Validate the output against the defined criteria.

Step 1: Configure List Report Annotations

@EndUserText.label: 'Travel Booking Projection'
@AccessControl.authorizationCheck: #CHECK
@Metadata.allowExtensions: true
@Search.searchable: true
define view entity ZC_TravelBooking
  as projection on ZI_TravelBooking
{
  key TravelUUID,
      TravelID,
      AgencyID,
      CustomerID,
      BeginDate,
      EndDate,
      TotalPrice,
      CurrencyCode,
      Description,
      Status,

      /* List Report Annotations */
      @UI: {
        lineItem: [ {
          position: 10,
          importance: #HIGH,
          type: #AS_LINK,
          semanticObjectAction: 'display'
        } ],
        identification: [ {
          position: 10,
          label: 'Travel ID',
          type: #AS_LINK,
          semanticObjectAction: 'display'
        } ],
        selectionField: [ { position: 10 } ]
      }
      TravelID,

      @UI: {
        lineItem: [ { position: 20 } ],
        identification: [ { position: 20 } ],
        fieldGroup: [ { qualifier: 'General', position: 20 } ],
        selectionField: [ { position: 20 } ]
      }
      Description,

      @UI: {
        lineItem: [ {
          position: 30,
          type: #AS_DATETIME,
          formatOptions: { displayMode: #DATE_ONLY }
        } ],
        identification: [ { position: 30 } ],
        fieldGroup: [ { qualifier: 'General', position: 30 } ],
        selectionField: [ { position: 30 } ]
      }
      BeginDate,

      @UI: {
        lineItem: [ {
          position: 40,
          type: #AS_DATETIME,
          formatOptions: { displayMode: #DATE_ONLY }
        } ],
        identification: [ { position: 40 } ],
        fieldGroup: [ { qualifier: 'General', position: 40 } ],
        selectionField: [ { position: 40 } ]
      }
      EndDate,

      @UI: {
        lineItem: [ {
          position: 50,
          type: #AS_NUMERIC,
          unit: CurrencyCode
        } ],
        identification: [ { position: 50 } ],
        fieldGroup: [ { qualifier: 'General', position: 50 } ]
      }
      TotalPrice,

      @UI: {
        lineItem: [ {
          position: 60,
          type: #AS_STATUS,
          criticality: 'StatusCriticality'
        } ],
        identification: [ { position: 60 } ],
        fieldGroup: [ { qualifier: 'General', position: 60 } ],
        selectionField: [ { position: 60 } ]
      }
      Status,

      /* Value Helps */
      @Consumption.valueHelpDefinition: [ {
        entity: {
          name: 'ZC_Agency',
          element: 'AgencyID'
        },
        useForValidation: true
      } ]
      AgencyID,

      @Consumption.valueHelpDefinition: [ {
        entity: {
          name: 'ZC_Customer',
          element: 'CustomerID'
        },
        useForValidation: true
      } ]
      CustomerID
}

Step 2: Configure Object Page Annotations

@UI: {
  headerInfo: {
    typeName: 'Travel Booking',
    typeNamePlural: 'Travel Bookings',
    title: {
      type: #STANDARD,
      value: 'TravelID'
    },
    description: {
      type: #STANDARD,
      value: 'Description'
    }
  },
  presentationVariant: [ {
    sortOrder: [ {
      by: 'BeginDate',
      direction: #DESC
    } ]
  } ]
}
define view entity ZC_TravelBooking
  as projection on ZI_TravelBooking
{
  // ... fields ...

  /* Object Page Facets */
  @UI.facet: [
    {
      id: 'GeneralInfo',
      type: #COLLECTION,
      label: 'General Information',
      position: 10
    },
    {
      id: 'TravelDetails',
      parentId: 'GeneralInfo',
      type: #FIELDGROUP_REFERENCE,
      targetQualifier: 'TravelData',
      label: 'Travel Details',
      position: 10
    },
    {
      id: 'FinancialInfo',
      parentId: 'GeneralInfo',
      type: #FIELDGROUP_REFERENCE,
      targetQualifier: 'FinancialData',
      label: 'Financial Information',
      position: 20
    },
    {
      id: 'Items',
      type: #IDENTIFICATION_REFERENCE,
      targetQualifier: 'Items',
      label: 'Travel Items',
      position: 20
    },
    {
      id: 'StatusInfo',
      type: #FIELDGROUP_REFERENCE,
      targetQualifier: 'StatusData',
      label: 'Status',
      position: 30
    }
  ]

  /* Field Groups */
  @UI.fieldGroup: [ {
    qualifier: 'TravelData',
    position: 10,
    label: 'Travel Details'
  } ]
  TravelID,

  @UI.fieldGroup: [ {
    qualifier: 'TravelData',
    position: 20
  } ]
  Description,

  @UI.fieldGroup: [ {
    qualifier: 'TravelData',
    position: 30
  } ]
  AgencyID,

  @UI.fieldGroup: [ {
    qualifier: 'TravelData',
    position: 40
  } ]
  CustomerID,

  @UI.fieldGroup: [ {
    qualifier: 'TravelData',
    position: 50
  } ]
  BeginDate,

  @UI.fieldGroup: [ {
    qualifier: 'TravelData',
    position: 60
  } ]
  EndDate,

  @UI.fieldGroup: [ {
    qualifier: 'FinancialData',
    position: 10,
    label: 'Financial Information'
  } ]
  BookingFee,

  @UI.fieldGroup: [ {
    qualifier: 'FinancialData',
    position: 20
  } ]
  TotalPrice,

  @UI.fieldGroup: [ {
    qualifier: 'FinancialData',
    position: 30
  } ]
  CurrencyCode,

  @UI.fieldGroup: [ {
    qualifier: 'StatusData',
    position: 10,
    label: 'Status'
  } ]
  Status,

  @UI.fieldGroup: [ {
    qualifier: 'StatusData',
    position: 20
  } ]
  CreatedBy,

  @UI.fieldGroup: [ {
    qualifier: 'StatusData',
    position: 30
  } ]
  CreatedAt
}

Step 3: Configure Actions and Data Actions

@UI: {
  lineItem: [ {
    position: 10,
    type: #FOR_ACTION,
    dataAction: 'submit',
    label: 'Submit Booking'
  } ],
  identification: [ { position: 10 } ]
}
TravelID,

@UI: {
  lineItem: [ {
    position: 20,
    type: #FOR_ACTION,
    dataAction: 'cancel',
    label: 'Cancel Booking'
  } ]
}
Status,

/* Header Actions */
@UI.headerInfo: {
  typeName: 'Travel Booking',
  actions: [
    {
      type: #FOR_ACTION,
      dataAction: 'submit',
      label: 'Submit'
    },
    {
      type: #FOR_ACTION,
      dataAction: 'cancel',
      label: 'Cancel'
    }
  ]
}

Step 4: Configure Value Helps

/* Simple Value Help */
@Consumption.valueHelpDefinition: [ {
  entity: {
    name: 'ZC_Agency',
    element: 'AgencyID'
  },
  useForValidation: true
} ]
AgencyID,

/* Value Help with Additional Properties */
@Consumption.valueHelpDefinition: [ {
  entity: {
    name: 'ZC_Customer',
    element: 'CustomerID'
  },
  additionalBinding: [
    {
      localElement: 'CustomerName',
      element: 'CustomerName',
      usage: #OUTPUT_ONLY
    },
    {
      localElement: 'CustomerEmail',
      element: 'Email',
      usage: #OUTPUT_ONLY
    }
  ],
  useForValidation: true
} ]
CustomerID,

/* Value Help with Filter */
@Consumption.valueHelpDefinition: [ {
  entity: {
    name: 'ZC_Material',
    element: 'MaterialID'
  },
  filter: {
    materialType: 'SERVICE'
  },
  useForValidation: true
} ]
MaterialID

Step 5: Configure Charts and Analytics

@UI.chart: [ {
  title: 'Travel Bookings by Status',
  description: 'Distribution of travel bookings',
  chartType: #COLUMN,
  dimensions: [ 'Status' ],
  measures: [ 'TotalPrice' ],
  qualifier: 'StatusChart'
} ]
define view entity ZC_TravelBookingAnalytics
  as projection on ZI_TravelBooking
{
  Status,
  @Aggregation.default: #SUM
  TotalPrice,

  @UI.chart: [ {
    qualifier: 'StatusChart',
    dimension: [ 'Status' ],
    measure: [ 'TotalPrice' ]
  } ]
}

Step 6: Configure Draft-Enabled UI

/* In Behavior Definition */
define behavior for ZI_TravelBooking alias TravelBooking
persistent table ztravelbook
draft table ztravelbook_d
lock master total etag LastChangedAt
with draft
{
  // ... CRUD operations ...

  draft action Resume;
  draft action Edit;
  draft action Activate;
  draft action Discard;
}

/* In CDS View - Draft Indicator */
@UI: {
  identification: [ { position: 1 } ],
  headerInfo: {
    typeName: 'Travel Booking',
    typeNamePlural: 'Travel Bookings'
  }
}
%isDraft,

Step 7: Create Fiori Launchpad App

{
  "sap.app": {
    "id": "sap.travel.booking",
    "type": "application",
    "title": "Travel Booking",
    "description": "Manage travel bookings"
  },
  "sap.ui5": {
    "dependencies": {
      "minUI5Version": "1.120.0",
      "libs": {
        "sap.fe": {}
      }
    },
    "routing": {
      "routes": [
        {
          "pattern": "",
          "name": "TravelBookingList",
          "target": "TravelBookingList"
        },
        {
          "pattern": ":TravelUUID:",
          "name": "TravelBookingObjectPage",
          "target": "TravelBookingObjectPage"
        }
      ],
      "targets": {
        "TravelBookingList": {
          "type": "Component",
          "id": "TravelBookingList",
          "name": "sap.fe.templates.ListReport",
          "options": {
            "settings": {
              "entitySet": "TravelBooking",
              "navigation": {
                "TravelBooking": {
                  "detail": {
                    "route": "TravelBookingObjectPage"
                  }
                }
              }
            }
          }
        },
        "TravelBookingObjectPage": {
          "type": "Component",
          "id": "TravelBookingObjectPage",
          "name": "sap.fe.templates.ObjectPage",
          "options": {
            "settings": {
              "entitySet": "TravelBooking"
            }
          }
        }
      }
    }
  }
}

Fiori Elements Templates

List Report

• Standard list with filtering and sorting
• Use for master data and transactional data
• Supports search, filters, and bulk actions

Object Page

• Detail page for single entity
• Use for editing and viewing details
• Supports tabs, field groups, and sub-objects

Worklist

• Task-based list
• Use for approval workflows
• Supports task actions and status updates

Overview Page

• Analytical dashboard
• Use for KPIs and charts
• Supports cards, charts, and tables

Best Practices

• Use semantic annotations (@EndUserText.label) for all fields
• Configure proper field groups for Object Page organization
• Use value helps for all foreign key fields
• Enable draft handling for complex editing scenarios
• Use proper field types (@UI.type) for better UX
• Configure criticality for status fields
• Use identification annotations for key fields
• Configure proper sorting and filtering
• Use charts for analytical data
• Test service binding before Fiori app development
• Use Page Map editor in Fiori Tools for visual configuration
• Follow Fiori design guidelines

Anti-Patterns

• Missing value helps for foreign keys (poor UX)
• Not using field groups (disorganized Object Page)
• Missing semantic annotations (poor accessibility)
• Not enabling draft for complex editing (data loss risk)
• Incorrect field types (poor display)
• Missing criticality for status fields (poor visual feedback)
• Not testing service binding first (wasted time)
• Ignoring Fiori design guidelines (inconsistent UX)
