How to download attachment stored in fnd_lobs table.

How to download attachment stored in fnd_lobs table

-        -          Open employee’s record and click on attachment icon.

-      Attach any new document under category as show below.

Now you can see the attachment symbol.

Attachment will be stored in fnd_lobs table.

below are queries to identify the attachment record.

select * from fnd_attached_documents

where entity_name='PER_PEOPLE_F'

and pk1_value=33579

order by creation_date desc;

select * from fnd_documents

where document_id=2349427;

select * from fnd_lobs

where file_id=2990785;

Now if you download the attachment through pl/sql procedure.

prerequisite 

- server directory -  where you want to download the file - generally database tier

- read/write access on the that directory.

- proper privileges on UTL_file packages

you can below procedure to download above attachment.

How to change current session language

How to change current session language in oracle

select * from per_business_groups;

output : no rows selected.

sometime some views will not return any data because of current session language.
Language install in your application is 'US', but what if your current session language is 'GB' or 'AR'.

sometimes your current session language depends on the tool that you are using or some default setup.

Generally it returns 'US'.
=====================================

select userenv('LANG') from dual;

output : US

=====================================

If it's not then you can your current session language by using alter session command.

eg. For AR

alter session set NLS_LANGUAGE='ARABIC';

eg. For GB

alter session set NLS_LANGUAGE='ENGLISH';

eg. For US

alter session set NLS_LANGUAGE='AMERICAN';

=================================================================

Set application message and token and retrieve it / Oracle application messages / FND Messages

Create a new application message as shown below.

You can set the message ,it's tokens, retrieve the value and then you can use it user hooks,form personalizations and other scripts.

DECLARE

   lv_msgdata   VARCHAR2 (32000);

BEGIN

   apps.fnd_message.set_name ('PER', 'XX_MSG_1');

   apps.fnd_message.set_token ('MSG_NAME', 'XXXX', TRANSLATE => TRUE);

   apps.fnd_message.set_token ('MSG_START_DATE',

                               '01-Jan-2014',

                               TRANSLATE      => TRUE

                              );

   lv_msgdata := apps.fnd_message.get ();

END;

How to Hide Reassign and Request for information button in workflow notification in oracle apps

HIDE REASSIGN BUTTON

Create an attribute with below details and drag and drop under the message for which you want to hide reassign button.

HIDE REQUEST FOR INFORMATION BUTTON

Create an attribute with below details and drag and drop under the message for which you want to hide reassign button.

Running the pre-processor after registering user-hook in oracle apps / Alternative of pre-processor

To run the pre-processor run one of the following commands:

cd $PER_TOP/admin/sql
Log into SQLPLUS as the APPS user
SQL> @hrahkall.sql

or

SQL> @hrahkone.sql


The first script will create all hook package bodies, whilst the second will
create hook package bodies for one API module only, and prompt for that
api_module_id.

==========================================================

Sometimes if you don't have server credentials then you can use below alternative to run the pre-processor through sqlplus

Log in to database through apps

SQL> @hrahkall.sql

instead of running above script you can execute below statement

exec hr_api_user_hooks_utility.create_hooks_all_modules;

SQL> @hrahkone.sql

instead of running above script you can execute below statement

exec hr_api_user_hooks_utility.create_hooks_one_module(p_module_id);

How to send attachment in oracle workflow notification / blob documents as attachment in oracle workflow notification

Create normal workflow process with simple notification as below.

Create a new document type attribute with below details.

drag and drop this attribute under "Attachment_notification"(notification message). Set the Attributes property as shown below.

Your workflow is complete. Now write the following PL/SQL code and run the workflow to get the notification.

TImeout functionality in workflow notification / Due date of notification in workflow

- Log in to workflow builder , open the workflow process

select the notification , right click and select properties then click on node tab.

it will be as below.

In the timeout section you can select timeout properties.

There are 3 options.


1- No timeout : It means no due date of the notification.


2 -  Relative Time : It is nothing but the constant time details .
you can set the value in days, hours and minutes combination.

3 - Item Attribute : You can create number type attribute and assign it here.

you can set the attribute value as below.


wf_engine.setitemattrtext (itemtype      => l_itemtype,
                                 itemkey       => l_itemkey,
                                 aname         => 'XXTIMEOUT',
                                 avalue        => 2880
                                );

2880 - it is  minutes.

if you want to set due date to 3 days then value should be =(24*60*3)= 4320.
