Attachment in Oracle Application

Attachment in Oracle Application

What is attachment in oracle application?

The attachments feature in oracle application enables users to link unstructured data, such

as images, word-processing documents, spreadsheets, or text to their application data. For



example, users can link images to items or video to operations as operation instructions.

Where to find an attachment?

There is an attachment icon in the oracle application toolbar that indicates whether the

Attachments feature is enabled in a form block. When the button is dimmed, the Attachment

feature is not available. When the Attachment feature is enabled in a form block, the icon

becomes a solid paper clip. The icon switches to a paper clip holding a paper when the

Attachment feature is enabled in a form lock and the current record has at least one attachment.

Attachment types:

An attached document can be:

1] Short Text

Text stored in the database containing less than 2000 characters.

2] Long Text

Text stored in the database containing 2000 characters or more.

3] Image

An image that Oracle Forms can display, including: bmp, cals, jfif, jpeg, gif, pcd, pcx, pict, ras,

and tif.

4] OLE Object

An OLE Object that requires other OLE server applications to view, such as Microsoft Word or

Microsoft Excel.

5] Web Page

A URL reference to a web page which you can view with your web browser.

Tables Involved:

For Importing Attachments in oracle application one has to populate following tables.

1. FND_DOCUMENTS

2. FND_ATTACHED_DOCUMENTS

3. FND_DOCUMENTS_TL

4. FND_DOCUMENT_DATATYPES.

5. FND_DOCUMENT_CATEGORIES

6. FND_DOCUMENTS_LONG_TEXT (Long text type attachment).

7. FND_DOCUMENTS_SHORT_TEXT (Short text type attachment).

8. FND_DOCUMENTS_LONG_RAW

9. FND_LOBS (File type attachments).

FND_DOCUMENTS:

FND_DOCUMENTS stores language-independent information about a document. For example,

each row contains a document identifier, a category identifier, the method of security used

for the document (SECURITY_TYPE, where 1=Organization,2=Set of Books, 3=Business

unit,4=None), the period in which the document is active, and a flag to indicate whether or not

the document can be shared outside of the security type (PUBLISH_FLAG).

Other specifications in this table include: datatype (DATATYPE_ID, where 1=short text,2=long

text, 3=image, 4=OLE object), image type, and storage type (STORAGE_TYPE, where

1=stored in the database, 2=stored in the file system).

The document can be referenced by many application entities and changed only in the define

document form (USAGE_TYPE=S); it can be used as a fill-in-the-blanks document, where each

time you use a template, you make a copy of it (USAGE_TYPE=T); or it can be used only one

time (USAGE_TYPE=O).Images and OLE Objects cannot be used as templates.

FND_ATTACHED_DOCUMENTS:

FND_ATTACHED_DOCUMENTS stores information relating a document to an application

entity. For example, a record may link a document to a sales order or an item. Each row

contains foreign keys to FND_DOCUMENTS and FND_DOCUMENT_ENTITIES. There is also

a flag to indicate whether or not an attachment was created automatically.

FND_DOCUMENTS_TL:

FND_DOCUMENTS_TL stores translated information about the documents in

FND_DOCUMENTS. Each row includes the document identifier, the language the

row is translated to, the description of the document, the file in which the image

is stored, and an identifier (MEDIA_ID) of the sub-table in which the document is

saved (FND_DOCUMENTS_SHORT_TEXT, FND_DOCUMENTS_LONG_TEXT, or

FND_DOCUMENTS_LONG_RAW).

FND_DOCUMENT_DATATYPES:

FND_DOCUMENT_DATATYPES stores the document datatypes that are supported. Initial

values are: short text, long text, image, and OLE Object (DATATYPE_ID=1, 2, 3, or 4).

Customers can add datatypes to handle documents stored outside of Oracle and use non-native

Forms applications to view/edit their documents. The table uses a “duplicate record” model for

handling multi-lingual needs. That is, for each category there will be one record with the same

CATEGORY_ID and CATEGORY_NAME for each language.

FND_DOCUMENT_CATEGORIES:

FND_DOCUMENT_CATEGORIES stores information about the categories in which documents

are classified. For example, documents may be considered “Bill of Material Comments”, “WIP

Job Comments”, etc. Document categories are used to provide a measure of security on

documents. Each form that enables the attachment feature lists which categories of documents

can be viewed in the form. This table uses a “duplicate record” model for handling multi-lingual

needs.

FND_DOCUMENTS_LONG_TEXT:

FND_DOCUMENTS_LONG_TEXT stores information about long text documents.

FND_DOCUMENTS_SHORT_TEXT:

FND_DOCUMENTS_SHORT_TEXT stores information about short text documents.

FND_DOCUMENTS_LONG_RAW:

FND_DOCUMENTS_LONG_RAW stores images and OLE Objects, such as Word Documents

and Excel spreadsheets, in the database.

FND_DOCUMENT_ENTITIES:

FND_DOCUMENT_ENTITIES lists each entity to which attachments can be linked. For

example, attachments can be linked to Items, Sales Orders, etc. Since the table uses a

“duplicate record” model for handling multi-lingual needs, for each document entity there will

be one record with the same DOCUMENT_ENTITY_ID and DATA_OBJECT_CODE for each

language.

Attachment upload through API:

Attachments can also be uploaded through an oracle provided API called

 FND_ATTACHED_DOCUMENTS_PKG.

It consist of three procedures

1) Insert Row

2) Update Row

3) Lock Row

Names of these procedures are self explanatory. insert row is used to insert a new row for

attachment data, update row is used to update existing row for a particular row and Lock Row is

used to lock a existing row for further modification.
