[ABAP] Hilfsvariablen mit LET-Ausdruck definieren

LET

  • Verwendung innerhalb von Operatoren NEW, VALUE, CONV, COND, SWITCH, REDUCE, FOR …
  • es konnen inplace Variablen oder Feldsymbole deklariert werden
  • Variablen, die im LET-Ausdruck definiert wurden k?nnen nur innerhalb des jeweiligen Scopes verwendet werden

Variante 1 (Variablendefinition, CONV)

* Carrier
PARAMETERS: p_carrid TYPE scarr-carrid DEFAULT 'LH'.

START-OF-SELECTION.

* Daten holen
  SELECT * FROM scarr INTO TABLE @DATA(it_carr).

  TRY.
* String zusammenbauen
      DATA(lv_carr_name) = CONV string(
* Hilfsvariablen per LET definieren
* ersten Carrier mit Carrid holen, kann Exception CX_SY_ITAB_LINE_NOT_FOUND werfen
                                        LET <c> = it_carr[ carrid = p_carrid ]
                                            dp  = |: |
* Hilfsvariablen verwenden
                                        IN
                                        |{ <c>-carrname }{ dp }{ <c>-url }| ).

      WRITE: / lv_carr_name.

* Exceptions abfangen
    CATCH cx_root INTO DATA(e_txt).
      WRITE: / e_txt->get_text( ).
  ENDTRY.

Variante 2 (Variablendefinition, COND)

DATA(lv_lang) = COND string(
* Hilfsvariablen per LET definieren
                             LET lang     = cl_abap_syst=>get_language( )
                                 lang_iso = cl_i18n_languages=>sap1_to_sap2( im_lang_sap1 = lang )
* Hilfsvariablen verwenden
                             IN
                             WHEN lang_iso = 'DE' THEN 'Deutsch'
                             WHEN lang_iso = 'EN' THEN 'Englisch'
                             ELSE 'andere Sprache'

WRITE: / lv_lang.

                                       output     = |{ idx };{ name };{ city };{ age_string }|
* Hilfsvariablen verwenden
