5. Define a KFF step by step
BaseTable表增加一个外键列
在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的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为
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

6. When-New-Form-Instance中加入FlexField的定义
在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',
2
7. FIELD => 'TO_ACCOUNT_PT',
CODE => 'GL#',
APPL_SHORT_NAME =>'SQLGL',
NUM => ':PARAMETER.CHART_OF_ACCOUNTS_ID',
ID => 'TO_ACCOUNT_PT_id',
VRULE =>
'nSUMMARY_FLAGnInAPPL=SQLGL;NAME=GL_NO_PARENT_SEGMENT_ALLOWEDnN0GL_
GLOBALnDETAIL_POSTING_ALLOWEDnEnAPPL=INV;NAME=INV_VRULE_POSTINGnN',
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_GLOBALnDETAIL_POSTING_ALLOWED nEnAPPL=''SQLGL'';
name=Parent Values are not allowednN'
);
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' );
3
8. 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为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的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.

FlexField的相关表
FND_ID_FLEXS:
This table captures the information of all the Key FlexFields. The main columns in this
table are:
APPLICATION_ID ‐ Column consists of Application ID
ID_FLEX_CODE ‐ Column KFF Code (like ‘GL#’, ‘AR#’ etc.)
ID_FLEX_NAME - KFF Name (like ‘Accounting Flexfield’, ‘Category Flexfield’..etc.)
APPLICATION_TABLE_NAME – Name of combination table (like
‘GL_CODE_COMBINATIONS’ , ‘FA_LOCATIONS’ etc.)
FND_ID_FLEX_STRUCTURES:
This table stores structure information about key Flexfields. Each Structure is uniquely
identified by
APPLICATION_ID – Module Code
ID_FLEX_CODE – Code of KFF
ID_FLEX_NUM – Number of a Structure
FND_ID_FLEX_SEGMENTS:
It captures the information of Segments. Each Segment is Uniquely identified by
APPLICATION_ID – Module Code
ID_FLEX_CODE – Key Flexfield code
8
13. ID_FLEX_NUM – Key flexfield structure number
SEG_NUM – Segment number
FLEX_VALUE_SET_ID – Flexfield value set identifier
FND_FLEX_VALUE_SETS:
This table captures the information of each Segment’s Value Set. Each Value Set is
Uniquely identified by FLEX_VALUE_SET_ID as Foreign Key of
FND_ID_FLEX_SEGMENTS Table.
FND_FLEX_VALUES:
This table captures the information each Value codes of a Value Set of a Segment. Each
Value Code is uniquely identified by
FLEX_VALUE_SET_ID
FLEX_VALUE_ID
FND_FLEX_VALUES_TL:
This table captures the information of each Value Description of a Value Set of a
Segment. Each Value Description is uniquely identified by FLEX_VALUE_ID.
