今回は、従来(ABAP 7.3以前)では有効化エラーとなってしまうけれど、
New open SQLだから書ける！という類のテーブル結合を書いてみます。
BSEGテーブルに、勘定科目の名称を付加する。
SELECT
t0~bukrs,
t0~belnr,
t0~gjahr,
t0~buzei,
t0~shkzg,
t0~dmbtr,
t2~waers AS waers_d,
t0~wrbtr,
t1~waers,
t0~hkont,
t3~txt20
FROM bseg AS t0
INNER JOIN bkpf AS t1
ON t1~bukrs = t0~bukrs
AND t1~belnr = t0~belnr
AND t1~gjahr = t0~gjahr
INNER JOIN t001 AS t2
ON t2~bukrs = t0~bukrs
INNER JOIN skat AS t3 "注目
ON t3~ktopl = t2~ktopl "注目
AND t3~saknr = t0~hkont "注目
AND t3~spras = @sy-langu
ORDER BY
t0~bukrs,
t0~belnr,
t0~gjahr,
t0~buzei
INTO TABLE @DATA(lt_data).注目すべきは、
SKAT：勘定コード表: テキストとT001：会社コードの結合条件と
SKAT：勘定コード表: テキストとBSEG：会計伝票明細の結合条件
つまり、3つのテーブルにまたがる結合条件を記述しているのです。
これを、従来からある(Classic) Open SQLで書くと有効化時にエラーが発生します。
少しプログラムを改変しました。(20171018)
