Popup Definition

@EndUserText.label: 'Entity for popup'
define abstract entity z2ui5_cds_test_popup
{
  @Consumption.valueHelpDefinition: [{ entity: { name: 'I_Country', element: 'Country' } }]
  @EndUserText.label: 'Country'
  SearchCountry : land1;
  @EndUserText.label: 'Valid To'
  @UI.defaultValue: '99991231'
  NewDate       : abap.dats;
  @EndUserText.label: 'Message Type'
  MessageType   : abap.int4;
  @EndUserText.label: 'Update data'
  FlagUpdate    : abap.char(1);
  @EndUserText.label: 'Show Messages'
  FlagMessage   : abap_boolean;
}

abap2UI5 Popup Call

  METHOD z2ui5_if_app~main.

    IF client->check_on_init( ).

      DATA(lo_dialog) = NEW z2ui5_cl_cds_action_dialog(
        val   = VALUE z2ui5_cds_test_popup( searchcountry = `US` )
        title = `Enter Parameters` ).
      client->nav_app_call( CAST #( lo_dialog ) ).
      RETURN.

    ENDIF.

    lo_dialog = CAST #( client->get_app_prev( ) ).
    IF lo_dialog->was_confirmed( ).
      DATA(ls_cds_result) = CONV z2ui5_cds_test_popup( lo_dialog->result( )->* ).
    ENDIF.

  ENDMETHOD.

CDS Value Help

Renders a table select dialog for any CDS view. Visible columns come from the entity metadata; @ObjectModel.text.element adds description columns.

abap2UI5 Value Help Call

  DATA(lo_vh) = NEW z2ui5_cl_cds_value_help(
    cds_view_name = `I_COUNTRY`
    element       = `Country`
    title         = `Select Country` ).
  client->nav_app_call( CAST #( lo_vh ) ).

On return, read the selection:

  lo_vh = CAST #( client->get_app_prev( ) ).
  IF lo_vh->was_confirmed( ).
    DATA(lv_country) = lo_vh->result_value( ).
  ENDIF.

CDS List Report

Renders a Fiori-Elements-style list report for any CDS view, driven entirely by its annotations:

• Columns from @UI.lineItem (position, label, importance-based responsive popin)
• Filter bar from @UI.selectionField (contains-search for text fields, * wildcards supported)
• Criticality columns from @UI.lineItem.criticality / @UI.dataPoint.criticality
• Amount/quantity columns from @Semantics.amount.currencyCode / @Semantics.quantity.unitOfMeasure
• Title from @UI.headerInfo.typeNamePlural, live row count
• Row navigation to a generated object page (row matched via @ObjectModel.semanticKey)

abap2UI5 List Report Call

client->nav_app_call( NEW z2ui5_cl_cds_list_report(
  cds_view_name = `I_COUNTRY`
  title         = `Countries`
  max_rows      = 500 ) ).

CDS Object Page

Renders an object page for a single record of a CDS entity:

• Header title/description from @UI.headerInfo
• Header attributes from @UI.identification (fallback: first visible fields)
• Status attributes with criticality from @UI.dataPoint
• Sections from @UI.facet fieldGroup references (order + labels), fallback to @UI.fieldGroup qualifiers
• User-format dates/times, Yes/No booleans, amounts/quantities with unit via @Semantics

abap2UI5 Object Page Call

"val: any structure typed after the CDS entity
client->nav_app_call( NEW z2ui5_cl_cds_object_page( val = ls_row ) ).

CDS Worklist

Renders a simple read-only table of a CDS view with @UI.lineItem columns (fallback: all visible fields):

client->nav_app_call( NEW z2ui5_cl_cds_worklist(
  cds_view_name = `I_CURRENCY`
  title         = `Currencies` ) ).

CDS Overview Page

Renders a grid of cards (table or KPI) for multiple CDS views:

client->nav_app_call( NEW z2ui5_cl_cds_overview_page(
  title = `Business Overview`
  cards = VALUE #(
    ( cds_view_name = `I_COUNTRY`  title = `Countries`  card_type = `TABLE` max_rows = 5 )
    ( cds_view_name = `I_LANGUAGE` title = `Languages`  card_type = `KPI` ) ) ) ).
