Responsibilities:
A responsibility is a level of authority in Oracle Applications that lets users access only those Oracle Applications functions and data appropriate to their roles in an organization.
Request Group:
It is a collection of concurrent Programs. It is used to request programs from the responsibility.
Data Group:
It is a collection of Modules used to integrate one or more Modules for cross application transfer of data, cross application reporting and cross application reference. If we want to get data from other Modules we need to define those modules in the Data Group.
Functions:
A function is a part of an application’s functionality that is registered under a unique name for the purpose of assigning it to, or excluding it from, a menu (and by extension, a responsibility).
Menu:
A menu is a collection of Sub‐Menus and Functions.
Concurrent Program:
It is an instance of an execution file, along with parameter definitions and incompatibilities. Several concurrent programs may use the same execution file to perform their specific tasks, each having different parameter defaults and incompatibilities.
Concurrent Program Executable:
It is an executable file that performs a specific task. The file may be a program written in a standard language, a reporting tool or an operating system language.

Concurrent Request:
It is a request to run a concurrent program as a concurrent process.
Concurrent Process:
It is an instance of a running concurrent program that runs simultaneously with other concurrent processes.
Concurrent Manager:
It is a program that processes user’s requests and runs concurrent programs. System Administrators define concurrent managers to run different kinds of requests.
Value Set:
The value set is a collection (or) container of values. It provides list of values to the end user to accept one of the values as report parameter value.
Profiles:
A user profile is a set of changeable options that affects the way your applications run. Oracle Application Object Library establishes a value for each option in a user’s profile when the user logs on or changes responsibility.
Key Flexfields:
They are used to capture mandatory or Key Business information of the Organization. Each Key Flex Field is having its own base Table.
Descriptive Flexfields:
They are used to capture the additional or extra Business information of the organization. DFF are used to add extra accounts, those changes from one business to another business. All DFF columns are defined as Attribute Columns. All these columns are defined in the transaction table itself. There are around 5000+ DFF available.
FlexField Qualifiers:
A Flex field qualifier identifies a particular segment of a key flex field. These are based on Key Flex Fields (KFF). FFQs are varry from one KFF to another KFF and it is not compulsory that all the KFF should have FFQs.
Segment Qualifiers:
A Segment Qualifier identifies a particular type of value in a single segment of a key flex field. Segment Qualifier is based on FFQs and it is not compulsory that all the FFQs should have Segment Qualifiers.
Dynamic Insertion:
Dynamic Insertion is the insertion of new valid combination into a Key Flexfields Combinations Table from a form other than the combinations form.
Alerts:
Oracle Alert facilitates the flow of information within your organization by letting you create entities called alerts. Oracle Alert will send messages or perform predefined actions in an action set when important events occur. Alert is a mechanism that checks your database for a specific exception condition. Alerts are used to monitor your business information and to notify you of the information you want.
Standard Request Submission:
SRS provides you with a set of windows for running reports and Programs and a set of windows for creating groups of reports and programs to run together.
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.

When we install Oracle Database by default system will creates SYS and SYSTEM schemas. These consist of all Data Dictionary Tables. Like this if we install Oracle Applications System will automatically creates schemas of all Modules (i.e. GL, AR, AP, etc.) with the respective module name as User and Password. Along with these schemas some special Schemas i.e. APPS, APPLSYS, APPLSYSPUB will be created for special purpose.

APPS Schema:

  • It is Public Schema.
  • The APPS schema is an ORACLE schema that has access to the complete Oracle Applications data model. It is analogous to the SYSTEM schema, which has access to the entire database.
  • AutoInstall creates the necessary grants and synonyms between the schemas.
  • Oracle Applications responsibilities connect to an APPS schema.
  • There is one APPS schema for every product installation group.
  • It consists of a collection of public synonym of all the objects of all the schemas in the Application database. All the Procedures, Functions and Packages created must be stored in this Schema.

APPLSYS Schema:
This is a special Schema consists of the files starts with FND, ALR, WF and AD.
APPLSYSPUB Schema:
This schema is a collection of public synonyms of all FND Tables, which are used for User verification. This is the Gate Way User ID of Oracle Applications.
Few Other Base Product Schemas:

  • GL ( General Ledger )
  • INV ( Inventory)
  • AP ( Accounts Payables)
  • APPLSYS ( Application Object Library)
  • ALR ( Alerts)
