Error Message = 3205: '~WF_ADHOC-1446' is not a valid role or user name

Question

Hi,
I have an Item attribute of type 'Role' ('CREDIT_COMMITTEE_MEMBERS') and I am using that attribute as performer for two notification activities.
For first notification, I create an adhoc role and assign it to the attribute and the notification goes successfully.
I want to send reminder to the people who have not responded to the first notification.
So I used the following query:
SELECT recipient_role
FROM wf_notifications
WHERE (message_name = 'MSG_TO_CREDIT_COMM_NEED_APPR' or message_name = 'MSG_REMINDER_CREDIT_COMM')
AND item_key = itemkey
AND status = 'OPEN';
The following code was used to update the Item attribute of type "Role"
FOR rec_cc_role_names IN cur_cc_role_names
LOOP
IF l_role_count = 0 THEN
l_role_users := rec_cc_role_names.recipient_role;
ELSE
l_role_users := l_role_users || ' ' || rec_cc_role_names.recipient_role;
END IF;
l_role_count := l_role_count + 1;
END LOOP;
wf_directory.createadhocrole
( role_name => l_role_name,
role_display_name => l_role_display_name,
notification_preference => 'MAILTEXT',
role_users => l_role_users,
expiration_date => NULL);
wf_engine.setitemattrtext
( itemtype => 'XXCCVOTP',
itemkey => itemkey,
aname => 'CREDIT_COMMITTEE_MEMBERS',
avalue => l_role_name);
The second notification activity is throwing the below error
Error Name = WFNTF_ROLE
Error Message = 3205: '~WF_ADHOC-1446' is not a valid role or user name.
Error Stack =
Wf_Notification.SendGroup(~WF_ADHOC-1446, XXCCVOTP,
MSG_REMINDER_CREDIT_COMM, 07-APR-10, WF_ENGINE.CB)
Wf_Engine_Util.Notification_Send(XXCCVOTP, 154009, 186344,
XXCCVOTP:MSG_REMINDER_CREDIT_COMM)
Wf_Engine_Util.Notification(XXCCVOTP, 154009, 186344, RUN)
Kindly help.
Thanks,
Amit

Answer 1

The users list was null for the role, which was causing the error. The query populating the user list was not returning any row.
