LENGTH

[Arslan1]

Hi, the length lengths of the structdescr->components table are doubled. how do I solve it?

SELECT lifnr, surbel, tedbf, eysbel, degkul, degtar, degsaa, iso_9001, iso_9001_t,
      iatf_16949, iatf_16949_t, surbel_t, iso_14001, iso_14001_t, iso_45001,
      iso_45001_t, iso_27001, iso_27001_t, iso_50001, iso_50001_t, iso_genel, iso_genel_t
          FROM zbtmm_t_0001 WHERE  (  ( iso_genel_t >= '20230101'  AND iso_genel_t <= '20250101' ) OR
              ( iso_50001_t  >= '20230101'  AND iso_50001_t  <= '20250101' ) OR
              ( iso_27001_t  >= '20230101'  AND iso_27001_t  <= '20250101' ) OR
              ( iso_45001_t  >= '20230101'  AND iso_45001_t  <= '20250101' ) OR
              ( iso_14001_t  >= '20230101'  AND iso_14001_t  <= '20250101' ) OR
              ( surbel_t     >= '20230101' AND surbel_t     <= '20250101' ) OR
              ( iatf_16949_t >= '20230101'  AND iatf_16949_t <= '20250101' ) OR
              ( iso_9001_t   >= '20230101'  AND iso_9001_t   <= '20250101' ) ) INTO TABLE @DATA(lt_analok).


DATA(tabledescr) = CAST cl_abap_tabledescr( cl_abap_typedescr=>describe_by_data( lt_analok ) ).
DATA(structdescr) = CAST cl_abap_structdescr( tabledescr->get_table_line_type( ) ).

DATA index TYPE i value 1 .

LOOP AT structdescr->components INTO DATA(component).

  WRITE: / index , ' ' , component-name ,  ' '  , component-type_kind , ' ' , component-length.

  index = index + 1.

ENDLOOP.

It's the length in bytes, so in a Unicode system (all systems since ABAP 7.53) where each character is 2 bytes, you simply divide by 2 to get the number of characters (cl_abap_char_utilities=>charsize).

Do it only when it's a character-based type of course.

NB: a question title like "Length in RTTS is doubled" would be better than just "LENGTH".

EDIT: your question is not about "ABAP Connectivity", better choose "ABAP Development" in SAP Managed Tags.
