我尝试使用功能模块REUSE_ALV_FIELDCATALOG_MERGE
传递ddic中的字段标签,以显示在alv报告的列标题中。
但是,这没有用。
如果我评论I_STRUCTURE_NAME = 'TY_YNAH_CUS_OBJ_REQ'
行,它会给我运行时错误状态
ABAP程序行比内部表格宽。
但如果我取消注释,该程序仍然无法正常工作

REUSE_*ALV*
个功能模块。我建议切换到CL_SALV_*
类。文档更好,有更多示例程序(DEMO_SALV_*
),您可以获得支持。TYPE ... BEGIN OF ... END OF ...
在ABAP级别上组装结构类型,据我所知,各个字段的字典类型首先转换为ABAP类型,然后才组装成结构类型。无论如何,原始字段的字典引用丢失了。不要在代码中定义输出表的结构,而是使用字典结构。答案 1 :(得分:2)
你有一些你可能不知道的错误(SAP有时会非常困惑 而不是透明的错误消息)。我找到了一个我的工作实例,看看它,特别是评论。
首先,数据定义:
TYPE-POOLS slis. "import you need for REUSE_ALV_FIELDCATALOG_MERGE
DATA:
lt_fieldcat TYPE slis_t_fieldcat_alv,
BEGIN OF G_IT_MATERIAL occurs 0,
MATNR LIKE MARA-MATNR,
MTART LIKE MARA-MTART,
MAKTX_DE LIKE MAKT-MAKTX,
MAKTX_FR LIKE MAKT-MAKTX,
MAKTX_IT LIKE MAKT-MAKTX,
ERNAM LIKE MARA-ERNAM,
ERSDA LIKE MARA-ERSDA,
LAEDA LIKE MARA-LAEDA,
END OF G_IT_MATERIAL.
您必须直接使用LIKE
定义本地结构,否则REUSE_ALV_FIELDCATALOG_MERGE
的解析器将无法找到它。
选择你的东西:
SELECT ma~matnr ma~mtart ma~ernam ma~ersda ma~laeda
de~maktx as maktx_de fr~maktx as maktx_fr it~maktx as maktx_it
FROM mara as ma
LEFT JOIN MAKT as de ON de~matnr = ma~matnr AND de~spras = 'DE'
LEFT JOIN MAKT as fr ON fr~matnr = ma~matnr AND fr~spras = 'FR'
LEFT JOIN MAKT as it ON it~matnr = ma~matnr AND it~spras = 'IT'
INTO CORRESPONDING FIELDS OF TABLE g_it_material
WHERE ...
动态创建字段目录:
CALL FUNCTION 'REUSE_ALV_FIELDCATALOG_MERGE'
EXPORTING
I_PROGRAM_NAME = sy-repid
I_INTERNAL_TABNAME = 'G_IT_MATERIAL'
I_INCLNAME = sy-repid
CHANGING
ct_fieldcat = lt_fieldcat
EXCEPTIONS
inconsistent_interface = 1
program_error = 2
OTHERS = 3.
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
现在显示ALV网格:
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
EXPORTING
it_fieldcat = lt_fieldcat "you could also give a structure
"i_structure_name = 'ZMM_SMATERIAL' "here instead of the fieldcat
TABLES
t_outtab = g_it_material
EXCEPTIONS
program_error = 1
OTHERS = 2.
请注意,解析器还需要72个字符的最大行数。

结构slis_fieldcat_alv
提供了几个不同的文本组件,用作列标签。所选文本取决于当前列宽(它本身通常取决于显示的数据长度)。确保相应地更改它们!
通常的技术是:通过传递I_STRUCTURE_NAME
,您将获得与此DDIC结构相对应的字段目录(更改参数ct_fieldcat
)。然后根据需要修改此内部表,并将修改后的表传递给REUSE_ALV_GRID_DISPLAY
。
如果我不区分不同大小的文本版本,我使用以下宏将所有文本字段设置为相同的值。宏需要一个本地工作区ls_fieldcat
(线型为ct_fieldcat) and a local string variable
lv_text`才能工作。
define set_field.
* Feld &1 für Anzeigefeld &2 den Wert &3 zuweisen
ls_fieldcat-&1 = &3.
modify ct_fieldcat from ls_fieldcat
transporting &1
where fieldname cp '&2'.
end-of-definition.
define set_text_direct.
lv_text = &2.
set_field seltext_s &1 lv_text.
lv_text = &2.
set_field seltext_m &1 lv_text.
lv_text = &2.
set_field seltext_l &1 lv_text.
end-of-definition.
