SOA/BPM/Human Tasks 11g -- add new task participant through Workflow API

Heya folks. Got a question that's been driving me nuts, hope you can help.
I have a bunch of Human Tasks in a BPMN process. Each task is pretty simple -- for assignment a single stage only; parallel approval; list of participants is passed in -- via the task payload -- as a comma-delimited list. When the task is initiated it produces a root task, and one child task for each participant. So, say we have participants "fgolfer,atreyvaud" we get three task objects: the "master" or root task and one each for fgolfer and atreyvaud.
Now what I want to do is add another approver (let's say "gfrog") -- i.e. create a new task for gfrog which is a child of the master task and leaves the tasks for fgolfer and atreyvaud as they are. As far as I can figure, this is NOT a Reassign nor an Ad-Hoc Route. Applying either of those to an existing task effectively removes the existing user from the task and assigns it to the new user.
On another track, if I programmatically create a new task (with initiateTask() from the Task service, using the values from an existing task), I seem to get a NEW master task with attendant child tasks, while leaving the existing master task and children.
Make sense? Neither of these outcomes is what I want.
Seems like this should be pretty simple but for the life of me I can't figure it out. I could create an FYI task or a todo task or a subtask but again this isn't what I want -- need to create a task with all the custom outcomes and such.

In case folks are playing along at home, I've yet to find a solution for this. Because I need to move forward with my project, I've decided I can't do it through the Workflow API and I'm taking a different route -- basically, triggering a custom task outcome which returns to the same Human Task in the BPMN flow, thus starting the task again. Before doing that I update the task's payload, which contains the task assignees.
I'm not happy with this, it seems like a nasty hack to overcome a limitation with the Workflow API.
Understand, though, I'm not saying this is impossible through the Workflow API, just that I haven't found a way to do it. I've spent 2-3 person weeks on this and it's time to move on.

User cannot add new task in a project

Hi everyone,
I've got a issue with Project Server 2013.
The situation : I create a new project then, I add some resources (which are users of the AD) and I don't add new task in this project because I want that the user creates all the task.
But when he's in the "Task" page (PWA/Tasks.aspx) and he want to add a new task (ribbon TASKS -> Add a row -> Add a new Task), the new project is not present in the drop down "Project" , if I want that the project
appears, I need to add a task with the user as a ressource.
Is there any way to automatically add the project in this list without add a task for the specific resource ?
Thanks,
Patmol

Hi Patmol6,
Please note that PWA/My task is NOT INTENDED to create tasks and assign them to resources. The process to create a project plan at project initiation and to assign resources to tasks must be done:
either in Ms Project Pro connected to your server and using enterprise resources,
or with PWA: open your project from the project center, then navigate to the schedule page, edit the schedule, create the build team, create tasks and assign resources on tasks.
"My task" page in PWA is meant to make tasks updates by team members.
Hope it clarifies the process.

'Claim' a Human Task through Workflow API

There is no function to "Claim" a task that is assigned to a group, through Workflow API.
There is a function to "Acquire" the task but after acquiring, the task cannot be completed (it throws exception):

and if viewed through the default worklist application, there is no action available to the task after "Acquiring" through API.
How can we create a custom worklist application and complete tasks which are assigned to a group of users ?

Can you post how you are acquiring it and how you are attempting to complete it?

Listing the Human tasks through Workflow API

The workflow API uses oc4jadmin as the user to get the workflow context. what if we dont have the credentials of oc4jadmin but of a normal user to whom a task is assigned. I am not able get the workflow context by using the credentials of a simple user.
I am using :
workflowContext = getTaskQueryService().authenticate(WF_MANANAGER_UN, WF_MANANAGER_PW, LDAP_DOMAIN, worklistUser);
List tasks = getTaskQueryService().queryTasks(getWorkflowContext(), displayColumns, optionalInfo, "My+Group", null, whereclause, null, 0, 0);
when i change the user name and password from oc4jadmin, it throws an exception of "null pointer"

Hi,
We solved this issue by applying the following steps:
* Create a shared library on the OC4J container using the same name (oracle.ifs.client), but another version (10.1.2). Actually, give it the version of your Content Services version.
* Upload the following JAR files to the shared library from the previous step: axis.jar, commons-discovery-0.2.jar, commons-logging-1.0.3.jar, content-ws-client.jar, http_client.jar, log4j-1.2.14.jar, wsdl4j-1.5.1.jar. Important: use the JAR files from you Content Services installation, not the JAR files from the Oracle AS installation (that containes another version of those JAR files).
* When you deploy the client application that accesses Content Services make sure you import the oracle.ifs.client shared library, but include a max-version attribute that equals your own shared library. That way, the correct JAR files are loaded instead of the newer version.

OIM 11g: Add process tasks as a result of a Request?

Is it possible in OIM 11g to have the result of a Request be that 1 or more process tasks are added to an an account's process?
The out-of-the-box Request framework seems to be very attribute driven (Modify Provisioned Resource, Self Modify Provisioned Resource), and I suppose we could add an attribute to trigger process tasks to be added, however, without going into detail, we'd really just like to be able to add the process task with no process form updates.
Has anyone attempted anything like this?

Sure you can. Create a plugin on the request status:
<plugin pluginclass="com.custom.eventhandlers.request.RequestCompleted" version="1.0" name="RequestCompleted">
<metadata name="status">
<value>Request Completed</value>
</metadata>
</plugin>
In your code, using benEntity.getEntityKey() you can get the "Users-Object Instance For User.Key" value for the instance the request is for. Then search the user's existing instances of that resource object type (findObjects) and match it to the "Users-Object Instance For User.Key" value from the result set. Then get the process instance key. From there you can use this code to get the task details:
Map taskMap = new HashMap();
String taskName = map.get(resourceName);
taskMap.put("Process Definition.Tasks.Task Name",taskName);
tcResultSet rs = taskOper.getTaskDetail(processInstanceKey,taskMap);
long taskKey = rs.getLongValue("Process Definition.Tasks.Key");
And finally this code to insert the task:
provIntf.addProcessTaskInstance(taskKey, processInstanceKey);
And done!

Task to add new row and values to Table?

Hi, I am new to SSIS, I have a table that I would like to capture daily currency conversion rates. In my Control Flow
pane, I've been able to use a web service task to get a string value of the conversion rate pass it to an XML task, and connect it to at Data Flow Task. So now I'm not sure what to do from here. I would like to input the daily values into my table:
[CurrencyID] [int] IDENTITY(1,1) NOT NULL,
[CurrXDate] [datetime] NOT NULL,
[Country] [nvarchar](50) NOT NULL,
[CurrXRate] [float] NOT NULL,
insert into tbl_CurrXrates
(CurrXDate, Country, CurrXRate)
values
(getdate(), 'USD', @[User::ConversionRate])
What data tasks and order would I use to add a new row to my table which I think would be a simple insert statement. Hope my
question makes sense.

You can put into a package variable and use as part of the insert statement via a SSIS expression to drive a Execute SQL Command to insert it or
Have the value off the webservice dumped to a XML file and then consume it with XML Source which will allow the values to be inserted into the table (e.g. OLEDB Destination)

Oracle Reports 11g - Add new report server

I have installed Weblogic 10.3.2 and Forms and Reports 11.1.0 ontop.
I have configured my forms in the same way as 10g iAS, by adding to formsweb.cfg etc etc. The forms are fine.
On 10g iAS reports, I used to select the report item from the iAS OEM screen and then edit configuration, changing the sourceDir, tempDir and cacheDir.
Alternatively, instead of uning the in-process server, how can I add a new report server and use that intead? I would prefer to add a new report server. I cannot see the section in the doco that explains this.

Hi,
Creating new reports servers isnt too bad in 11g. Please see the following oracle note on creating additional reports standalone reports servers for 11g Reports running on WebLogic: Oracle Note 961174.1
Hope this helps.
Thank you,

How to add new attribute for triggering workflow?

Dear Expert,
I want to create condition for triggering workflow.
I am working on travel request workflow, using BUS2089.
my requirement is to differentiate or make condition of triggering workflow based on trip activity type,
but I can't find any attribute about trip activity type.
how to add activity type to be available for create condition?
thanks

Hi,
If am not wrong you are trying to raise event when ever there is a new travel request raised, so the BOR would be availbel in the workflow container to be more preciese it would be available in the event container, so you need to find out the right attribute in the BOR where the trip type is assigned and validate this in the start conditions i mean in the basic data of the workflow where you activate the event linkage.

Edited by: aneeshmathew on May 4, 2011 4:44 AM

Hi ,
Table can not be created through personalization ,but u can create a region where u can create the table and then add this region to the standard page through personalization,using below steps
1.) create the stack layout bean through personalization .
2.) in extend property of stack layout bean give the full pacth of your new custom region containing the custom table.
3.) Of course u have to import the custom page to MDS.

PWA 2013 "Add a new task" - inconsistent task insertion behavior

Hi all!
New to the forum and wondering if anyone out there has insight into what I've encountered with the "Add a new task" feature in on-prem Project Server 2013.
First some context... I am setting up 12-month projects for different teams to forecast and log their administrative and reactive time for the year.
We are tracking this within enterprise projects. The projects have a series of summary tasks that serve to categorize work. There is a placeholder task within each summary task that establishes duration and where we may assign generic resources
to establish a baseline cost for the 12 month period for that category of work. The vision is for team members to go to their PWA Tasks list, "Add a new task", select the project and the summary task to categorize and add their new task to
the project, enter the task information, and submit for approval.
My issue appears when the Project Manager approves a task and opens the project in Project Professional because the system appears to exhibit inconsistent
behavior - Scenario 1 vs Scenario 2 below.
Scenario 1 – Project structure prior
to adding a new task:
Project Summary Task, 260d
-Summary Task, 260d
--Placeholder Task, 260d, generic resources assigned, ID=n
-Summary Task, 260d
Team member adds a new task and submits. The new task is inserted as a child task to the summary task selected when adding
the new task. This is what PWA Approval Preview shows and what is found when file is opened in Project Professional:
Project Summary Task, 260d?
-Summary Task, 260d?
--New task just added, 2d?, named resource assigned, ID=n
--Placeholder Task, 260d, generic resources assigned, ID=n+1
-Summary Task, 260d
Scenario 2 – Same project structure as scenario 1... team member submits a new task
and the new task is inserted per below. This is NOT what PWA Approval Preview shows. PWA shows the new task as a child of the summary task. Once approved and the file is opened in Project Professional, the task instead reflects as a child
task to the placeholder task, and impacts the duration of the original summary task:
Project Summary Task, 260d?
-Summary Task, 2d?
--Placeholder Task, 2d?, generic resource assignments, ID=n
---New task just added, 2d?, named resource assigned, ID=n+1
-Summary Task, 260d
I am using separate project files to produce the scenario, and as far as I can tell they are set up exactly the same, but one file consistently produces
scenario 2 behavior and the other consistently produces scenario 1 behavior. It seems that something is different between the two files and causing the issue, but I can't figure out what it is.
Any idea what I could do to establish consistent (preferably Scenario 1) task insertion behavior from PWA?

Anyone else running into this? We're now on the April CU and still experiencing this apparent bug. I've replicated it in different PWA instances using "Add a new task" from both the timesheet and tasks.
It only happens on certain projects as Greg mentioned... One way we've been able to pinpoint where it's taking place: since the bug causes a task to become a summary task, and since most of our tasks have assignments, if a project contains any summary
tasks with assignments, those may be an early indicator of the bug (after we rule out PM-induced summary task assignments).
We're seeing this impact our project actuals and reports, so there is a fair amount of going back through approval history and restoring actual hours to the correct calendar dates in the Project Client. Not ideal, because we are planning to lock that
capability down in the near future.
On a whim, I tried using the "Save for sharing" method to fix the issue, and new tasks appeared to insert correctly after that. Seems OK for a workaround (we'll see how durable it is), but better yet would be consistent new task insertion
behavior.

Call Function STARTING NEW TASK ----- Resource not available

Hi All,
I am calling a Function Module in new task using STARTING NEW TASK.
If the resources are not available for the Dialog Process to start, for how long will SAP keep on trying to acquire the resources and in case if it fails to acquire resource, then what will happen
Regards,
Abhishek

Hi,
From memory (as it is a long time since I've done this) you can call another function module or SAP command that will tell you how many work processes are currently available before you actually then start the new task. This can help you to avoid this issue and also stop you from eating up all available work processes on a system which will annoy all other users!
I think this is the FM
CALL FUNCTION 'SPBT_INITIALIZE'

IMPORTING

Thanks for your reply and confirmation, really appreciate it.
Yes, I found the difference of the invoking process API and was able to invoke bpel process using direct and ADF-BC binding by following Edwin's blog. But I have not found any official reference to compare this API difference between 10g and 11g ( I will mark this question as answered if anyone can find an official source from oracle, need to prove it to the team). The API to work with human task workflow seems pretty much the same between 10g and 11g.

ADF forms based on BPM human tasks - Invoking webservices/view objects.

Hi All,
Is anyone aware of whether the following is a valid implementation that has been carried out before.
1. ADF forms based on BPM 11G human tasks.
2.The ADF forms invoke webservices via Webservice data controls. It is pertinent to note that the webservice bring back complex data types. We've tried writing a few forms, resulting in data benig brought back, but not being able to print them to the screen.
3. The ADF forms also use View Object based on sql to bring back tables of data. If view objects are embedded within the forms, the applciation gives rise to a null pointer exception.
Considering the form will be invoked via a BPM worklist entry, is there a setting or configuration we should consider before hand. Is this feasible, is there knowledge of this being done commercially.
Any examples or information regarding the same will be immensely helpful.
Thanks and Regards,
Preethi.
NB : I have posted this in the BPM forum as well as I feel it is relevant to both BPM and ADF.

Hi Joonas.
Plese let me explain me better for your understanding
A big summary for what I meant it's the following:
1- In the procces you made, when you add the HT activity, you have to implement it, this means declare the input(s) parameters you want. This implementation create the .task file.
2- Create an application, and projects as HT you have. Each poject are based on the .task file, and automatically create a Data Control (for each project based on a .task) with all you need.
This w'll be an empty application, so you can customize it all you want. The task selected should have all the parameters previously defined. Those parameters can change if you want.
2- Create a page(s) in the task flow for the task implementation. You can even split the the payload of the task in differents pages, create your custom pages and any logic you need.
3- An important aspect is how to match these application with the HT implemented in the process. It's possible, it's a configuration en the Enterprise Manager.
4- Deploy your application
All these are explain in the book I mentioned
Th book you can find it here:

We have a BPM Process which has 2 roles. SKURequester and SKUChangeAnalyst.
When we initiate the flow , it opens up a screen and we populate data and click "SUBMIT".
It goes to ChangeAnalyst for approval.
It is working fine in Development Env.We could see a new task created for ChangeAnalyst once the requester SUBMIT's his task.
But in Test env, Once the requester submit's his task .It's not creating a task row for ChangeAnalyst in BPM workspace.
We verified the roles assigned to the user.Everything is same.
Repeatedly seeing the following error in LOGS.
