Wf_notification use

I am new to the workflow. I want to use wf_notification.send. For the spec of this api, there is a msg_type parameter. What value I need to pass for this parameter? Please give me an example. Morever, I plan to use this wf_notification.send for the post-notification function. What kind of mode it will be when the post-notification function is called?

Hello, for the WF_NOTIFICATION, you can refer to Oracle Workflow API Reference Release 2.6.3 Chaper 4-12.
You can download this documentation from http://www.oracle.com
Cheers!

Looking for an example of someone using WF_NOTIFICATION()

I need a good example of how someone has used the special message function known as WF_NOTIFICATION() in order to embed an Oracle Framework Region in a Workflow HTML message body. I'm very familiar with the documentation on how to use the function, but would like to see a "real world" example.
Thank you,
Marilyn Montgomery

Hi Mike
You could save the workflow as an application and then write a simple script that tells the application to launch multiple times.
But you'll find it many times faster to do it the other way round, and run a looping AppleScript from a single Automator action.
(Your iPod must be set up in disk mode.)
set ipod_name to "Name of your iPod goes here" -- edit this line and put the name of your pod in inverted commas
tell application "Finder" to set ipod_ready to exists disk ipod_name
if ipod_ready then
set text_folder to (choose folder with prompt "Choose the folder containing notes for your iPod.")
set file_names to list folder text_folder without invisibles
repeat with file_name in file_names
set file_path to text_folder & file_name as string
if file type of (info for file_path) is "TEXT" then
tell application "Finder"
move file file_path to folder "Notes" of disk ipod_name
end tell
end if
else -- ipod not mounted
display dialog "Mount your iPod first!" buttons {"OK"} default button 1 with icon caution giving up after 5
end if
Copy and paste this into a Run AppleScript action, edit to supply the name of your own ipod, and see how it goes.
Hope this helps,
H

Message body is empty, when calling wf_notification.send ,

hi,
i am sending a messages to 5 peoples, using wf_notification.send api.
but the when i check the emails, mesage body is empty.
prior to calling wf_notification.send Api,
my message body has been generated by the message attribute of type document(plsqlclob), iam using wf_engine.setItemAttribute and the argument avalue is like this
avalue=> 'plsql:koc_overtime_web_pkg02.show_mgr_message_TST/'||itemtype || ':' || ItemKey) for setting this message attribute(this will generate html)
Shall i need to use any callback function in my send api.
regards.
zameer.

If you are using WF_ENGINE.SetItemAttrText API, I see that you have a workflow item that is launched. In such a case you could just have a notification activity within the same process that will send the notification and the e-mail appropriately.
Why do you use WF_NOTIFICATION.Send using an attribute value that is set from a Workflow item.
Typically WF_NOTIFICATION.Send function is used to send a notification outside of a workflow process. Typically you would use a workflow message definition and corresponding message attribute definition and use the following code to send the notification.
declare
    l_nid   number;
    l_user varchar2(320) := '&1';
    l_begin_date date;
begin
    l_nid := wf_notification.send(l_user, 'CS_MSGS', 'FYI_MESSAGE');
    wf_notification.setattrtext(l_nid, 'SENDER', 'Oracle Workflow Testing Mailer');
    wf_notification.setattrtext(l_nid, 'MESSAGE_TEXT', ' Message sent at '||to_char(sysdate,'DD-MON-RRRR HH24:MI:SS')||' DB server time');
    wf_notification.denormalize_notification(l_nid);
    commit;
end;
/As you can observe, I do not depend on any workflow item for any attribute information. Please note that in case if there is a requirement to depend on a workflow item, it is required that you need to pass a Callback function and Context to WF_NOTIFICATION.Send function in order for the workflow item attribute information to be copied over to notification attributes.

Workflow API which can be used to avoid sending notification to user

Hi Folks,
We want Workflow API which can be used to avoid sending notification to user for particular type of error.
Say we are using following API which are used to send notification to mailbox as soon as program run into error.
wf_core.context(c_v_package_name
,c_v_func_name2
,p_event.getEventName()
,c_v_task_id_prompt||l_n_task_id
,l_v_msg_data);
wf_event.seterrorinfo(p_event, c_v_result_error);
Now we want to restrict certain type of error to send as a notification however we want to keep this record in wf_notifications table for further investigation.
Thanks and Regards,
Javed Khan

Matt,
It looks like another person had a similar question before, see the following thread:

How to use PLSQL CLOB IN WORKFLOW

Dear all,
I have follwoing query with workflow.
I have developed FYI WF.
1) In my WF mail, I am getting click here to respond.
I want to hide this.
Pl. let me know how to do that?
2) I have developed a workflow with Document type.
I am calling a PL/SQL CLOB procedure to pass my values( 4 columns from a table)
I need to pass approximately 70 to 100 rows to clob.
when I pass 14 rows, I am not getting any error.
where as if I pass morethen 15 rows, I am getting follwoing error
"ORA-06502: PL/SQL: numeric or value error ORA-06512: at "APPS.WF_NOTIFICATION", line 5046 ORA-06512: at line 5 "
Pl. let me know, do I need to setup any thing in workflow from my side

Hi,
I'm not sure whether it is because of the length of variable.
However, did you use concatenation (||) to store the value in the varchar variable before putting it into the CLOB variable?
If so, perhaps you forget to reset the varchar variable inside the loop, thus making it longer and longer each loop.
You should empty the varchar variable by
loop
l_string := '';
-- your code, perhaps concat the variable
l_string := l_string || 'blah blah';
end loop;For the FYI Notification, perhaps you should check the Notfication in the Workflow Builder, whether it has an Attribute with Respond type on the Notification.
If you didn't put anything (only the message body) in the Notification, the message will suppose to be a FYI one.

ORA-20006: ORA-01722: invalid number ORA-06512: at "APPS.WF_NOTIFICATION"

Hi,
I am having a wft program, which checks a function activity and depending on the value returned sends difference notifications.
The package body completed successfully from backend and while running the workflow program it sends a notification also. But while opening the notification it gives the following error,
ORA-20006: ORA-01722: invalid number ORA-06512: at "APPS.WF_NOTIFICATION", line 5328 ORA-06512: at line 5
I have 3 procedures in my package body and all the 3 procedures have exceptions defined as follows, if they are using any workflow activities.
==========================================================
EXCEPTION
     WHEN OTHERS THEN
          WF_CORE.context (
          'WFCustCheck',
          'MisCustDataFromTableDoc',
          document_id,
          display_type,
          document,
          document_type,
          SQLERRM
RAISE_APPLICATION_ERROR (-20006, SQLERRM);
==========================================================
But I am not able to figure out what is causing this error. What does this "line 5328 ORA-06512: at line 5" in the error message indicate?. My package body has only 600 lines. And why is the error message not displaying the procedure name? though I have defined the procedure name in the exception.
What is the best way to get the procedure name in the error message? So that it becomes easier for identifying which procedure is causing the erro?
Please let me know.
Thanks

Hi,
Instead of the RAISE_APPLICATION_ERROR command, just replace that with RAISE;
The error is coming out of the package that is sending the notification (WF_NOTIFICATION), which is invoked when you open the notification. I'm guessing that line 5 is the line in your code though.
Are you using documents to send the notification, or are they purely defined in the .wft file?

Is Oracle Workflow customization possible using APIs?

Our Purchase Requisition gets approved through Oracle Workflow Notifications.
Now I need to change Recipient of Notification,i.e. to change workflow on runtime (by using trigger on wf_notifications table) depending on some conditions.
Please help which APIs should I call from trigger to change the forwarded to/ recipient.
Can I use directly Send(),Forward(),Cancel() etc APIs contained in Package WF_NOTIFICATION ?
I used Forward(), but it did not work.
Please help.

Just go through this link, you will get idea what to do for workflow

FYI Notification using wf_engine.abort_process

Hi everyone,
For a work item to be considered eligible for purging, all activities must be complete. This includes FYI notifications, which must be closed. So once i change the status of the activity to COMPLETE using wf_engine.abort_process, will this close the FYI notificatoin corresponding to that item key?
Thanks a lot
KK

Hi,
The cursor which the code uses does not check whether they are response required or FYI before aborting the process.
If the notification is open when the API is called, it is cancelled by calling WF_NOTIFICATION.cancel.
So - yes, it will close any open FYI notifications as well as open notifications which require a response.
HTH,
Matt

Need suggestion to Hide a region using SPEL.

Hi,
I want to hide 'Related Details' region(Header) from notification page if the workflow notification is a 'FYI' message.
How to do this in Standard page? can we do this using personalization?
Please suggest me.
Thanks & Regards,
Sagarika

Hi Anand,
I have gone through the link. It says about PPR event.
My requirement is like this,
I have two regions in notification page(Region1 & Region2)
From Region1 I can get the value of the message whether it is 'FYI' message or not.
based upon the message value I want to hide Region2.
My question is , how Region2 will get the message value of Region1?
I tried with SPEL.
Region1 use NotificationVO and the query is,
select notification_id, message_name, decode(message_name,'MANAP_MSG_FYI',1,0) RFlag from wf_notifications;
And Region2 contain Header region.
I want to hide Region2 using SPEL. So I set the render property of Region2 as ${oa.NotificationVO1.RFlag}
But this logic is not hiding the Region2 if its a FYI message.
Is there something I missed out here?
Please suggest.
Thanks & Regards,
Sagarika

WF_NOTIFICATION.send

Hi All,
I am trying to use WF_NOTIFICATION.send for the 1st time. The requirement is that I have following piece of code in my pl/sql package which is called form the function activity of the workflow. The following code is inside the loop of the supplier list. So I want to send the notification to each of the supplier picked up in the loop.
If it not giving me any error in pl/sql or workflow, with debug I have checked it it getting correct value for l_tp_contact but still when I log-in as the supplier (user) in the worklist there is no message to that supplier.
=====
l_notification_id := WF_NOTIFICATION.send (role      => l_tp_contact,
               context     => p_itemtype||':'||p_itemkey||':'||to_char(p_actid),
                              msg_type      => 'PONAWARD',
                              msg_name      => l_message_name);
===
Can some one please help.
Thanks!

I am guessing, because I haven't done this with PL/SQL code before, but when you say you are looping through suppliers, is this a loop in your PL/SQL or a loop in the workflow? I have had problems before with notifications not being generated from inside a workflow loop because I had my On Revisit set incorrectly (Reset instead of Loop) on the notification step.
Also, is the notification a response required notification or an FYI notification? Where the notification is an FYI, the status of the notification can be updated when generating the email, so querying open notifications on the supplier's worklist could be missing it where the email has been generated.
A good check for both of these is to see if you can find anything in the WF_NOTIFICATIONS table for these notifications?

Can somebody please guide me

The stack trace below the "ORA-06502: PL/SQL: numeric or value error: character string buffer too small" error suggests that this is being generated by the Wf_Notification.NTF_Table call. Given the way you have described the problem, I would assume that the HTML generated by that call for the data in l_cells is exceeding the length of your l_result variable (32767).
Have you checked the length of the data generated by this call for a single record and then divided 32767 by that number to work out the maximum number of rows you can support with this call?
If it is simply that you have too much data for WF_Notification.NTF_Table to produce the table within the 32767 limit, you try generating the HTML in smaller chunks and adding them to the CLOB bit by bit. For example, if 10 records work, then generate the HTML for 10 records, chop off the </table> from the result and add it to the clob. Then do the next 10 records (without the header this time) and chop off the <table> and </table> tags and add that to the clob. When you are done, add the closing </table> tag to the clob and return it.
I haven't done this with returning a clob, but I have done this with shorter strings to generate a HTML table with the standard look and feel but with headers in different places than could be done by default.

Send high priority/importance mails using wf_mail.send

Hello All,
I wish to using wf_mail.send to send emails with p_content_type => wf_notification.doc_html
I am getting the mails , however I need the mails to be sent with high importance or priority flag.
(For eg: In outlook we have high importance flag)
How can I do this using wf_mail.send ? In which parameter I need to mention this ?
If this is not possible in wf_mail.send, Is there an alternative?
Please help.
Thanks.

On the Message there is a field called Priority, choose High, Normal, or Low for the default priority of the message. The priority level simply informs the recipient of the urgency of the message. It does not affect the processing or delivery of the message.
Or if you don't want the default set, you can change it on the insertion of the Notification in a Process. It is on the tab "Node"

Thanks

Hi KK,
What error you are getting when you set the attributes '#FROM_ROLE' and 'SENDER'?
when you set '#FROM_ROLE' then Wf_Notification.Denormalize_Notification(nid) API will be called. If the attribute is 'sender' then event 'oracle.apps.wf.notification.setattrtext wll be rasied.

How Respond() function knows what NID to use

Hi, I need to respond a notification from my application, I read a lot of message about it, but I can't see how to get the notification ID (NID) to call respond() function, I saw the following example about it:
CREATE OR REPLACE PROCEDURE "RESPOND"
( itemtype in varchar2,
itemkey in varchar2,
response in varchar2,
responder in varchar2) is
x_sqlcode NUMBER;
x_sqlerrm char(512);
nid NUMBER;
begin
select B.notification_id into nid
from owf_mgr.WF_ITEM_ACTIVITY_STATUSES_V A,
owf_mgr.WF_NOTIFICATIONS_VIEW B
where A.item_type = itemtype
and A.item_key = itemkey
and A.ACTIVITY_STATUS_CODE = 'NOTIFIED'
and A.NOTIFICATION_ID = B.GROUP_ID
and B.RECIPIENT_ROLE = responder;
dbms_output.put_line('NID='||nid || ' RESPONSE='||response );
owf_mgr.wf_notification.setAttrText(nid, 'RESULT', response);
owf_mgr.wf_notification.respond(nid,null,responder);
EXCEPTION
When others then
x_sqlcode := sqlcode;
x_sqlerrm := sqlerrm;
DBMS_OUTPUT.PUT_LINE ('Error #: ' || x_sqlcode);
DBMS_OUTPUT.PUT_LINE (SUBSTR(1,70,x_sqlerrm));
end RESPOND;
but whats happend when the SELECT result is 2 nid's, because this workflow is waiting for 2 different notifications (from 2 different activities) at the same time ...
How I know what NID use?
how can I to distinguish both NID's?

Typically you want to replicate in your code what SAP is doing in theirs... I find the easiest way to achieve this is to turn on debugging (/h) and run the standard SAP transaction, and set Breakpoint > At Statement > Authority-Check and see what gets triggered... then you can be pretty sure you are checking the same objects, fields, and values.
