Floorplan Manager Codebeispiele (ABAP)

Dieser Artikel zeigt beispielhafte Listings für verschiedene Methoden, die im Floorplan Manager benötigt werden.

Grundlegende Informationen sowie weitere Quellen finden sich in Floorplan Manager (ABAP)

IF_FPM_GUIBB_LIST

GET_DEFINITION - Grundform

Signatur der Methode:

EO_FIELD_CATALOG - Enthält Feldkatalog in Form eines Strukturtyps, der alle Komponenten umfasst, die als Felder im Formular verwendet werden können
ET_FIELD_DESCRIPTION - Liste mit Feldbeschreibungen und beschreibenden Informationen zu den einzelnen Feldern
ET_ACTION_DEFINITION - Liste mit möglichen Aktionen

Beispielhafte Befüllung der Description-Tabelle für Form-GUIBB mit dem Ziel, Warnungen im FLUID-Designer zu vermeiden:

  METHOD if_fpm_guibb_form~get_definition.

    DATA: ...

    CLEAR:...
 
    ...
    ...
    ...

    " Definition of field catalog
    eo_field_catalog ?= cl_abap_structdescr=>describe_by_name( p_name = 'Z_S_SELECTION' ).


    " Build list of field descriptions for FPM containing mostly only field names
    " in order to prevent warnings in FPM designer
    APPEND VALUE fpmgb_s_formfield_descr( name = 'FISCYEAR' ) TO et_field_description.
    APPEND VALUE fpmgb_s_formfield_descr( name = 'ZDOMUSER' ) TO et_field_description.
    APPEND VALUE fpmgb_s_formfield_descr( name = 'ZDOMUSERNAME' ) TO et_field_description.
  ENDMETHOD.

GET_DEFINITION - Mit Button und Read-Only-Spalten

  method IF_FPM_GUIBB_LIST~GET_DEFINITION.

    DATA: lt_field_cat   TYPE ztt_list,
          ls_field_descr TYPE LINE OF fpmgb_t_listfield_descr,
          ls_action_def  type line of fpmgb_t_actiondef.

    eo_field_catalog ?= cl_abap_tabledescr=>describe_by_data( lt_field_cat ).

    ls_field_descr-name = 'LFDNR'.
    ls_field_descr-read_only = abap_true.
    ls_field_descr-condense = 'X'.
    APPEND ls_field_descr TO et_field_description.

    ls_action_def-imagesrc = 'ICON_SYSTEM_SAVE'.
    ls_action_def-enabled = abap_true.
    APPEND ls_action_def TO et_action_definition.
  endmethod.

GET_DEFINITION - Custom-Spaltenüberschriften

Zusätzlich: Felder mit individuellen Spaltenüberschriften sowie Editierbarkeit-Kennzeichen und Darstellung als Checkbox.

  METHOD if_fpm_guibb_list~get_definition.

    DATA: ...

    CLEAR:...
 
    ...
    ...

    APPEND VALUE fpmgb_s_listfield_descr( name = 'ZKSTL_K' ) TO et_field_description.
    APPEND VALUE fpmgb_s_listfield_descr( name = 'ZKSTL_T' ) TO et_field_description.
    APPEND VALUE fpmgb_s_listfield_descr( name = 'ZKRS_K' ) TO et_field_description.

    APPEND VALUE fpmgb_s_listfield_descr( name = 'REJECTED' header_label = TEXT-002 ) TO et_field_description.
  ENDMETHOD.

FLUSH - Mit Verarbeitung von Change-Log

Nachfolgendes Listing führt Aktionen abhängig von Change-Log aus. Laut SAP sollen Änderungen der Daten aber nicht im Flush statt finden, sondern im Get_Data. Vermutlich ist dieses Listing daher nicht mustergültig, sondern müsste die zu ändernden Daten abhängig von den Eingaben aus dem Change-Log im Flush an das Get_Data übergeben, und dort verarbeiten.
