Add visual filters (chart-based) to SAP Fiori Elements filter bar/value help using CAP or ABAP RAP.

AI 生成的概览

为 SAP Fiori Elements 的筛选栏和值帮助添加基于图表的可视化筛选器,适用于 CAP 或 ABAP RAP 项目。

功能
该技能指导在 OData V4 的 SAP Fiori Elements 筛选栏或值帮助对话框中添加基于图表的可视化筛选器(条形图或折线图)。它先收集实体、维度字段、度量字段、聚合方式和图表类型等必要输入。随后提供 CDS 注解、ABAP RAP 元数据扩展注解、前端 annotation.xml 内容以及清单配置。它还列出 CAP 和 RAP 项目的测试命令与常见错误。
适用场景
当 SAP Fiori Elements 应用需要在筛选栏或值帮助对话框中加入基于图表的筛选器时使用。适用于使用 OData V4 且需要配置聚合与图表注解的 CAP 或 ABAP RAP 项目。不适用于没有可视化筛选器的普通值帮助对话框。
运行要求
需要一个基于 OData V4 的 SAP Fiori Elements 项目,使用 CAP 或 ABAP RAP,并包含 CDS、ABAP 元数据扩展、annotation.xml 和 manifest.json 文件。测试部分引用 npm run watch- 、cds watch、npm run start-mock 和 npm start 等 npm 脚本,并提到 ADT MCP 和 Fiori MCP 服务器作为可选辅助。该技能不附带脚本,仅为说明文档。

SAP Fiori Visual Filter

Purpose

Add chart-based filters (Bar/Line) to filter bar or value help dialog (OData V4).


MANDATORY: Gather Required Inputs First

STOP and ASK the user for ALL of these inputs if ANY are missing from the prompt:

  1. Entity - Which entity to add the visual filter to
  2. Dimension field - The field to filter by (e.g., Category, Status, Destination)
  3. Measure field - The numeric field to aggregate (e.g., Amount, TotalPrice, ReservationPrice)
  4. Aggregation method - How to aggregate: sum, avg, min, or max
  5. Chart type - Bar or Line (recommend Bar as default)

DO NOT proceed with implementation until all inputs are confirmed.


CAP Implementation

Enable Aggregation (MANDATORY)

cds
@Aggregation.ApplySupported: {  Transformations: ['aggregate','groupby'],  AggregatableProperties: [{ Property: Amount }],  GroupableProperties: [Category]}

Aggregated Property (Measure)

cds
Analytics.AggregatedProperty #Amount_sum : {  $Type: 'Analytics.AggregatedPropertyType',  Name: 'Amount_sum',  AggregatableProperty: Amount,  AggregationMethod: 'sum'}

Chart Annotation

cds
UI.Chart #visualFilter : {  ChartType: #Bar,  Dimensions: [Category],  DynamicMeasures: ['@Analytics.AggregatedProperty#Amount_sum']}

✅ Uses DynamicMeasures

PresentationVariant

cds
UI.PresentationVariant #visualFilter: {  Visualizations: ['@UI.Chart#visualFilter']}

ValueList (on Dimension Field)

cds
Category @Common.ValueList #visualFilter: {  $Type: 'Common.ValueListType',  CollectionPath: 'EntityName',  Parameters: [    { $Type: 'Common.ValueListParameterInOut', LocalDataProperty: Category, ValueListProperty: 'Category' }  ],  PresentationVariantQualifier: 'visualFilter'}

SelectionFields

cds
UI.SelectionFields: [Category]

Manifest configuration (MANDATORY)

refer to the "Manifest Configuration" section below.


ABAP RAP Implementation (4 Steps)

CRITICAL: NEVER EDIT metadata.xml - IT IS READ-ONLY!

1. Backend CDS (MANDATORY) - Enable Aggregation Support

abap
@OData.applySupportedForAggregation: #FULLdefine root view entity ZC_ENTITY  provider contract TRANSACTIONAL_QUERY  as projection on ZR_ENTITY{  @Aggregation.default: #SUM  Amount;  Category;}

2. Backend Metadata Extension (MANDATORY) - Add Chart, PresentationVariant, SelectionField Annotations

abap
@UI.chart: [{  qualifier: 'visualFilter',  chartType: #BAR,  dimensions: ['Category'],  measures: ['Amount']}]@UI.presentationVariant: [{  qualifier: 'visualFilter',  visualizations: [{    type: #AS_CHART,    qualifier: 'visualFilter'  }]}]
annotate view ZC_ENTITY with{  @UI.selectionField: [{ position: 10 }]  Category;
  @EndUserText.label: 'Amount'  Amount;}

3. Frontend (annotation.xml)

Chart Annotation:

xml
<Annotations Target="EntityType/Category"><Annotation Term="Common.ValueList" Qualifier="visualFilter">  <Record Type="Common.ValueListType">    <PropertyValue Property="CollectionPath" String="EntityName"/>    <PropertyValue Property="PresentationVariantQualifier" String="visualFilter"/>    <PropertyValue Property="Parameters">      <Collection>        <Record Type="Common.ValueListParameterInOut">          <PropertyValue Property="LocalDataProperty" PropertyPath="Category"/>          <PropertyValue Property="ValueListProperty" String="Category"/>        </Record>      </Collection>    </PropertyValue>  </Record></Annotation></Annotations>

4. Manifest configuration (MANDATORY)

refer to the "Manifest Configuration" section below.


Manifest Configuration

json
"@com.sap.vocabularies.UI.v1.SelectionFields": {  "layout": "CompactVisual",  "initialLayout": "Visual",  "filterFields": {    "Category": {      "visualFilter": {        "valueList": "com.sap.vocabularies.Common.v1.ValueList#visualFilter"      }    }  }}

CRITICAL: Manifest Configuration Structure

NEVER nest visualFilter inside a settings property!


Testing

CAP Projects

bash
npm run watch-<app-name>  # e.g., npm run watch-manage-travel# or use generic watch script if availablecds watch

RAP Projects

bash
npm run start-mock # Needs metadata refresh
npm start          # No refresh needed - fetches metadata from live backend at runtime
  • Consult fiori mcp server if available on how to refresh metadata for sap/cloud systems in case of RAP

Key Differences

CAP:

  • Aggregation + measures defined in CDS
  • Uses DynamicMeasures
  • Aggregation and chart defined in same place

RAP:

  • Aggregation defined in backend CDS only
  • Uses Measures (not DynamicMeasures)
  • Metadata is read-only

Common Mistakes

  • Backend Changes are not activated.
  • Qualifier mismatch between Chart, ValueList, PresentationVariant, and manifest
  • Wrong path in manifest (use full vocabulary path)
  • Missing SelectionField annotation
  • Non-numeric measure field
  • Missing compact visual layout configuration in manifest

RAP:

  • Missing backend aggregation support
  • Using DynamicMeasures instead of Measures
  • Adding Common.ValueList in backend instead of frontend (ValueList MUST be in frontend annotation.xml)
  • Adding UI annotations directly in CDS projection view instead of metadata extension
  • Trying to use @Consumption.valueHelpDefinition for visual filters (that's for value help dialogs, not visual filters)

Best Practices

  • Always activate backend changes in ADT MCP before testing
  • Use 1 dimension + 1 measure per visual filter
  • Prefer Bar charts for better readability
  • Keep qualifier names consistent across all annotations
  • Test with different data volumes
  • Always include layout: "CompactVisual" and initialLayout: "Visual" in manifest

RAP Specific:

  • ALWAYS use ADT MCP to modify backend files when available
  • Chart + PresentationVariant → Backend metadata extension (.ddlx.acds)
  • Common.ValueList → Frontend annotation.xml (CANNOT be in backend)
