我是靠谱客的博主端庄唇彩，最近开发中收集的这篇文章主要介绍abap--关于集(set)的读取(如读取成本中心组下的所有成本中心)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

在sap中很多地方使用了集(set)来存储层次关系的数据,如:
Cost Center Group
Cost Element Group
Order Group
Statistical Key Figure Group
Activity Type Group
Profit Center Group
Business Process Group
Cost Object Group
Account Group
WBS Element Group
Fund Group
Functional Area Group
Grant Group
Business Entities Set
Real Estate Set
Buildings Set
Rental Units Set
Rental Agreements Set
Management Contracts Set
Settlement Units Set
General Contracts Set
... 等等....，具体参见SETCLS表.

setcls:Set Classes(SETCLASS(4))
SETCLST: Set Class Descriptions(LANGU(2),SETCLASS(4))
setheader:Set Header and Directory(SETCLASS(4),SUBCLASS(10),SETNAME(24))
setnode:Lower-level sets in sets((SETCLASS(4),SUBCLASS(10),SETNAME(24),LINEID(10))
setleaf:Values in Sets(SETCLASS(4),SUBCLASS(10),SETNAME(24),LINEID(10))

代码样例
该样例代码是提取某个成本中心组下的成本中心到range: s_kostl
*&---------------------------------------------------------------------*
*&      Form GET_TREE
*&---------------------------------------------------------------------*
*       text
*----------------------------------------------------------------------*
* --> p1        text
* <-- p2        text
*----------------------------------------------------------------------*
form get_kostl.
data: l_count type i.
data: begin of i_tree occurs 0,
      setname like setnode-setname,
    end of i_tree.
data: i_subtree like i_tree occurs 0 with header line,
    i_temptree like i_tree occurs 0 with header line.
select setname into i_tree
    from setheader
    where setclass = '0101' and subclass = '1000'
      and setname in s_cengrp.
    read table i_setheader with key setname = i_tree-setname.
    if sy-subrc = 0.
      append i_tree to i_tree.
    endif.
endselect.
i_subtree[] = i_tree[].
l_count = 1.
while l_count > 0.
    read table i_subtree index 1.
    delete i_subtree index 1.
    select subsetname as setname
      into table i_temptree
      from setnode
      where setclass = '0101'
       and subclass = '1000' and subsetcls = '0101'
       and subsetscls = '1000' and setname = i_subtree-setname.
    append lines of i_temptree to i_tree.
    append lines of i_temptree to i_subtree.
    describe table i_subtree lines l_count.
endwhile.
select valsign as sign   valoption as option
    valfrom as low   valto   as high
    into table s_kostl
from setleaf
    for all entries in i_tree
where setclass = '0101'
    and subclass = '1000' and setname = i_tree-setname.
endform.                    " GET_KOSTL
