Define a KFF step by step

BaseTable 表增加一个外键列

Base Table 中定义一个字段 XXX_ID ,这个用于保存 KFF表记录的主键(对于 Base Table 就是外键列),比如对于本例,如果要增加一个 Account KFF ,需要在 Base Table 上增加一个 XXX_ID外键字段用于保存捕获的 CODE_COMBINATION_ID

Block 中创建一个 Flexfield的隐藏 item

Block中定义一个隐藏字段用于保存上边一步创建的 FK 字段,设置 canvas NULL TEXT_ITEM property class

Block 中创建一个 Flexfield显示字段

创建了隐藏字段,当然要创建一个显示的字段让用户来输入,这里我们需要创建一个 non-database 字段用来展示合并的科目值, subclass Information 继续使用TEXT_ITEM, 设置合适 canvas 来显示,LOV 设置为 'ENABLE_LIST_LAMP' 'Validate from list' is set to No

When-New-Form-Instance 中加入FlexField 的定义

When-New-Form-Instance 中加入 FlexField的定义,当然好的戏,代码类似于

        

 SELECT CHART_OF_ACCOUNTS_ID INTO :PARAMETER.CHART_OF_ACCOUNTS_ID

         FROM ORG_ORGANIZATION_DEFINITIONS

         WHERE ORGANIZATION_ID = :PARAMETER.ORG_ID;

         FND_KEY_FLEX.DEFINE(

         BLOCK => 'TOMAI_MAIN_HEADER_BLK',

          FIELD => 'TO_ACCOUNT_PT',

          CODE => 'GL#',

          APPL_SHORT_NAME =>'SQLGL',

          NUM => ':PARAMETER.CHART_OF_ACCOUNTS_ID',

          ID => 'TO_ACCOUNT_PT_id',

          VRULE => '\\nSUMMARY_FLAG\\nI\\nAPPL=SQLGL;NAME=GL_NO_PARENT_SEGMENT_ALLOWED\\nN\\0GL_GLOBAL\\nDETAIL_POSTING_ALLOWED\\nE\\nAPPL=INV;NAME=INV_VRULE_POSTING\\nN',

           REQUIRED => 'N',

           DINSERT  => 'Y',

          VALIDATE => 'FULL',

          USEDBFLDS => 'N');

FND_KEY_FLEX.DEFINE 的用法

FND_KEY_FLEX.DEFINE( 
block => 'Custom block',
Field => 'BTL_KFF',-- 第三步创建的显示 item
ID => 'XXX_ID',-- 第二步创建的隐藏 item
Appl_short_name => 'SQLGL',
Code => 'GL#',--ID_FLEX_CODE 
Num => '101',--Chart of account
Vrule => 'GL_GLOBAL\nDETAIL_POSTING_ALLOWED \nE\nAPPL=''SQLGL'';
name=Parent Values are not allowed\nN'
);


Trigger 中调用FlexField 标准的方法

Trigger包括

    PRE-QUERY

    POST-QUERY

    PRE-INSERT

    PRE-UPDATE

    WHEN-VALIDATE-RECORD

    WHEN-NEW-ITEM-INSTANCE

WHEN-VALIDATE-ITEM

代码类似于:

WHEN-VALIDATE-ITEM
    if ( :system.mode = 'NORMAL' ) then
       fnd_flex.event( 'WHEN-VALIDATE-ITEM' );
    end if;
WHEN-NEW-ITEM-INSTANCE
    app_standard.event('WHEN-NEW-ITEM-INSTANCE');
    fnd_flex.event('WHEN-NEW-ITEM-INSTANCE' );
POST-QUERY
--Loads the flexfields (in our case, it populates
--the concatenated field on execute query).
    FND_FLEX.EVENT('POST-QUERY');
PRE-QUERY
--If you don't do this, whatever query criteria you may enter in
-- the concatenated flex field, it is not taken into account.
    FND_FLEX.EVENT('PRE-QUERY' );
KEY-LISTVAL
    APP_STANDARD.EVENT('KEY-LISTVAL');
    FND_FLEX.EVENT('KEY-LISTVAL' );

一般情况下,我们会把 fnd_flex.event这样的代码放在 Form 级别,这样我们新加的 Trigger只要不是 Override 模式, 那么 fnd_flex.event都会被执行到,当然如果你的 trigger override 模式或者需要比较复杂的 Flexfield 的业务逻辑,那么你就必须手工添加 fnd_flex.event 代码到你的 Trigger中。对于本例 Account KFF 来说,因为要校验 Account ID 是否有效,所以需要在 When-Validate-Item中加入一些其他校验

   FND_FLEX.EVENT('WHEN-VALIDATE-ITEM');

    IF :BLOCK.XXX_ID = -1 THEN

    FND_MESSAGE.SET_STRING('You Have Selected An Undefined Code Combination !');

    FND_MESSAGE.SHOW;

    RAISE FORM_TRIGGER_FAILURE;

END IF;

Flexfield 相关的API

FND_KEY_FLEX.DEFINE in Developer Guide
Use FND_KEY_FLEX.DEFINE for a key flexfield on a foreign key or combinations form.
Attention: We provide combinations form syntax so you can
convert any existing non–Oracle Applications combinations
forms you may have from SQL*Forms 2.3 to Oracle Forms 4.5.
However, the API for key flexfields may change in future
versions of Oracle Applications, so we recommend that you do
not create any new key flexfields that are not provided by
Oracle Applications.

You should not use a colon ( : ) in block.field references for the
VALATT, COPY, or DERIVED arguments. The arguments for these
routines go to an Oracle Application Object Library cover routine and
are not directly interpreted in PL/SQL.
