自建屏幕字段双击功能1

---恢复内容开始---

业务背景：

有时候我们可能对自建屏幕上的字段要进行双击操作，要触发自建屏幕的双击需要设置一些东西，本文将介绍一种触发自建屏幕字段双击的例子。

解决步骤

新建一个程序，然后再新建一个屏幕，注意勾选回应双击
处理屏幕的PBO和PAI，设置STATUS和USER_COMMOND.

 1 PROCESS BEFORE OUTPUT.
 2 *&SPWIZARD: PBO FLOW LOGIC FOR TABLECONTROL 'ZTAB_CTRL'
 3   MODULE ZTAB_CTRL_INIT.
 4 *&SPWIZARD: MODULE ZTAB_CTRL_CHANGE_TC_ATTR.
 5 *&SPWIZARD: MODULE ZTAB_CTRL_CHANGE_COL_ATTR.
 6   LOOP AT   G_ZTAB_CTRL_ITAB
 7        INTO G_ZTAB_CTRL_WA
 8        WITH CONTROL ZTAB_CTRL
 9        CURSOR ZTAB_CTRL-CURRENT_LINE.
10 *&SPWIZARD:   MODULE ZTAB_CTRL_CHANGE_FIELD_ATTR
11     MODULE ZTAB_CTRL_MOVE.
12     MODULE ZTAB_CTRL_GET_LINES.
13   ENDLOOP.
14 
15  MODULE STATUS_0100.
16 
17 PROCESS AFTER INPUT.
18 *&SPWIZARD: PAI FLOW LOGIC FOR TABLECONTROL 'ZTAB_CTRL'
19   LOOP AT G_ZTAB_CTRL_ITAB.
20     CHAIN.
21       FIELD ZTIF_LOG-ZIFID.
22       FIELD ZTIF_LOG-ZIFNO.
23       FIELD ZTIF_LOG-TYPE.
24       FIELD ZTIF_LOG-CRDAT.
25       FIELD ZTIF_LOG-CRTIM.
26       FIELD ZTIF_LOG-ZBZNO.
27       MODULE ZTAB_CTRL_MODIFY ON CHAIN-REQUEST.
28     ENDCHAIN.
29   ENDLOOP.
30   MODULE ZTAB_CTRL_USER_COMMAND.
31 *&SPWIZARD: MODULE ZTAB_CTRL_CHANGE_TC_ATTR.
32 *&SPWIZARD: MODULE ZTAB_CTRL_CHANGE_COL_ATTR.
33 
34  MODULE USER_COMMAND_0100.

其中模块STATUS_0100和USER_COMMAND_0100是需要我们完成的，其他字段皆是TAB_CTRL向导模式生成的。

设置STATUS，注意设置F2（鼠标双击，这是一个SAP预设的功能）的功能码（其实我们注意观察的话，可以看到标准的SAP STATUS都是设置了F2的功能码的）
