Read in Workflow definitionidentity programatically

Hi I have a series o workflows that I have developed.
I wish each workflow to log its version number when it starts running.
Workflows are developed in Visual Studio and use the standard XAMLX files and cannot find an object that lets me read in the Definitionidentity structure
Thanks in advance for any information

HI SourenS,
First
Definitionidentity can be used to allow multiple versions of a workflow to execute side-by-side.
See: Side by Side Versioning in WorkflowServiceHost
If you want to use the persisted WorkflowIdentity to retrieve the correct workflow, and definition from the dictionary, take a look at this sample:
// Get the WorkflowApplicationInstance of the desired workflow from the specified
// SqlWorkflowInstanceStore.
WorkflowApplicationInstance instance = WorkflowApplication.GetInstance(instanceId, store);
// Use the persisted WorkflowIdentity to retrieve the correct workflow
// definition from the dictionary.
Activity definition = WorkflowVersionMap[instance.DefinitionIdentity];
WorkflowApplication wfApp = new WorkflowApplication(definition, instance.DefinitionIdentity);
// Configure the WorkflowApplication with persistence and desired workflow event handlers.
ConfigureWorkflowApplication(wfApp);
// Load the persisted workflow instance.
wfApp.Load(instance);
// Resume the workflow...

Angie

Hello,
I search the correct RFC to read the Workflow Inbox. I would like to develop a JAVA Class to connect the Inbox and then to show the workitems on a web screen. I use the SAP JCo to connect the SAP System. But until now, i don't found the correct RFC to connect the Workflow Inbox in the Workplace.
Can anybody help me or know anybody the correct RFC?

Slow performance to read/write shared variables programatically

We are using datasocket read and write functions to read and write shared variables programatically (in the same machine) but we only achieve a performance of aprox. 200 reads/writes per second. We are using Labview 8.6 with DSC.
Is possible to get better results? That performance is normal?
Any help would be appreciated. Thank you in advance.

Hi MMCDAT,
I think this value can
be normal as you can see in this link:
http://zone.ni.com/devzone/cda/tut/p/id/5037
As you can see, the
limit for datasocket depends on your Ethernet limitations, even if you as using
it just in one PC:
http://digital.ni.com/public.nsf/websearch/6AC9E65734E53F9A8625672400637ECC?OpenDocument
You can improve the
performance changing the update mode or Vis configurations:

Reader Extensions workflow

I make XFA forms and usually just add reader extensions through Acrobat but now have a form from which I will need to extract data from more than 500 users so can't do it this way.
Can I just purchase the Reader Extension module to allow me the license to do this and if so what is the workflow for this module?
Thanks.

Transaction Reading in Workflow

Hi Experts,
I need to create a workflow which will take care of sending a mail to the managers and senior managers based on the duration the complain was created. Suppose from the time created no action taken on complain and it has become 24 hrs then the mail mentioning abt the no necesary action for the complain must go to the Sales or service manager, similarly if the time crosses 48 hrs, the respective GM's must be informed.
Any idea how to start and how to read the actual transaction of complain(BUS2000120). I will need to read the priority of the document and its date and time and also need to find the respective Manager and GM (sales or service).
your help with be highly appritiated.
Thanks,
SA

Hi, try using CRM_ORDER_READ in SE38 with your transaction ID, this will help you finding in which structures your data is stored. It will also help you seeing how the order_read FM call is performed.

Simultaneously reading multiple channel types programatically

Hi, I'm completely new to using NI DAQ so please forgive me if this is trivial. I am need to be able to simultaneously read 5 analog lines and up to 20 digital lines of an M-series multifunction card completely programatically, i.e. with no involvement of MAX, LabView, etc. (it's going to be incorporated into a Matlab program and has to be as independent as possible). I simply want to write a piece of C code that reads these channels at 2KHz and stores the data for later analysis. Is this possible with the NI DAQ library? (and if not, why not?) From what I've read so far, for some reason it doesn't seem to be a supported function of the DAQ library. Any advice welcome. Many thanks
Tom

Your M series board is not supported by the old NI-DAQ driver. It can only be used with the newer DAQmx driver included with the board. and while you can't have true simultaneous analog acquisition you can synchronously acquire 5 analog channels 20 digital inputs. The DAQmx driver includes some C example programs. You can download the latest version of DAQmx by going to http://www.ni.com/support/.
If you're not going to use LabVIEW for the data acquisition, you shouldn't post to this message board. There is a dedicated Multifunction DAQ forum and Measurement Studio vot VC++ message board.

OAI Event is not reading the workflow queue

I'm creating the workflow event using iStudio (created automatically by iStudio) with the following information:
Item Type: OAI Process Bundle: EDWARD
Internal Name: I_EDWARD_PAATRANSACTION_OAI_V1
Display Name: Receive Request EDWARD.PAATransaction:IN
Description: OAI Event
Event Action: Receive
Event Filter: oai.edward.paatransaction.oai_v1.receive_request.oai_v1
Cost: 0.0
I also create the event subscription for oracle.apps.wf.event.agent.create, oracle.apps.wf.event.event.create, and oracle.apps.wf.event.subscription.create and put the following information:
System: WFLOWDEV.MAXIMUSBC.CA
Source Type: External
Event Filter: oracle.apps.wf.event.subscription.create
Source Agent: <blank>
Phase: 1
Status: Enabled
Rule Data: Key
Rule Function: WF_EVENT_FUNCTIONS_PKG.RECEIVE
Workflow Item Type: EDWARD
Workflow Process Name: PAATRANSACTION
Out Agent: <blank>
To Agent: [email protected]
Priority: Normal
Parameters: <blank>
I can see that the interconnect OAI Hub is putting a message into the WF_IN queue but the event does not dequeue the message and run the process.
So, I don't know if I'm missing anything here or there is something wrong with my configuration.
Can anyone help me please?
Thanks,
Edward

Edward,
I am basing this reply on the OAI build I have on my laptop, which is an Oracle 9iAS Integration build, however I do not think that it has changed since.
Before you do this, it is always a good idea to add the "OAIHeader" objects to the Common View.
1. Under "Common Views", expand the "Business Objects" and find your Business Object (e.g. MY_BO)
2. Under the "Events", expand the "Events" to find your event (e.g. MY_EVENT)
3. Highlight you event (MY_EVENT), Right-click on your mouse, and choose "Edit". This will bring up the "Edit Event" window.
4. Choose "Add". This will create a new line.
The 'Name' will be blank.
The 'Type' will be "String".
The 'Owner' will be blank.
The 'Array' will be blank, and
The 'Default' will be 'NULL'.
5. On the 'Type' value ("String"), click on the value "String". This will bring up a pop-up list.
6. From this list, select "Data Type..."
7. Now click once anywhere in the "Edit Event" window. This will bring up a "Common Data Types" window.
8. Scroll down, find and highlight the the name "OAIHeader". Press 'OK'
9. Now back in the 'Edit Event' window, you will notice that the type is "OAIHeader".
10. Now give the "Name" (currently still blank) a value. Give it the name "OAIHeader" too.
11. Press 'OK'
12. You will now see that the Event now has "OAIHeader" information. Some of these values will be of interest and of use later.
The actual values for "EventName, EventVersion" etc. will be added to the data of the message at Runtime.
*** TIP: I always do the above exercise first for every Business Object event I create. Once I've included the 'OAIHeader', I then add all of the actual other message attributes to the message afterwards. ***
Create Content Based Routing Rules
In this example, I am going to route a message from a sending DB Adapter (DBAPP1) to the Workflow Adapter (WORKFLOW). Then once the message has been passed to the Workflow, it will be passed to the receiving DB Adapter (DBAPP2).
1. In iStudio, under the "Design" tab, expand the "Enabling Infrastructure".
2. Under "Content Based Routing", find your Business Object.
e.g. MY_BO
3. Expand the Business Object, and then expand the "Events" to find your event.
e.g. MY_EVENT
4. On the Event (MY_EVENT), highlight it, then right mouse click. Choose Edit.
5. A window will pop-up called "Content Based Routing: MY_EVENT"
6. Hit the "New" button.
7. Expand the message structure (MY_EVENT), and find the 'OAIHeader' node.
8. Expand the "OAIHeader" node, and select (highlight) the "SendingApplication" attribute.
9. Press 'Next'. This will move you onto the next screen.
10. From the drop-down list, choose the "==" Operator. Press 'Next'.
11. Enter a Value in the box. Since my sending application is "DBAPP1", type in "DBAPP1". Press Next.
12. Since I have completed the "source" CBR rules, check the "Condition Complete" radio button, and Press 'Next'.
13. Now in the next screen, select "WORKFLOW". Now press 'Finish'.
Perform the same as above, this time routing the message from the "WORKFLOW" adapter to your receiving adapter (e.g. 'DBAPP2'). If the Workflow message does not have the 'OAIHeader' information in it's structure, once again refer to the above and add it in.
Once you have completed all of your CBR configuration, use "File > Push Metadata" to send this new message structure and CBR rules to your adapters (DBAPP1, WORKFLOW and DBAPP2).

Yan

Reading system profile parameters programatically in ABAP

Hi,
Does anyone know how to read system profile parameters like icm/host_name_full using ABAP?
Thanks in advance!

You can use the following code to get the values. Really it is just reading a file which is stored on the application server.
report zrich_0001.
types: begin of tpar,
       status type sy-index,
       name(60) type c,
       user_wert(60) type c,
       default_wert(60) type c,
       end of tpar.
data: par_usub type table of tpar with header line.
data: par_sub type table of tpar with header line.
call 'C_SAPGALLPARAM' id 'PAR_USUB' field par_usub-*sys*
                      id 'PAR_SUB' field par_sub-*sys*.
loop at par_usub.
write:/ par_usub-name(30), par_usub-user_wert(20),
          par_usub-default_wert(20).
endloop.

Reading acceleration channel properties programatically

I am creating a virtual channel that is reading a TEDS compatible accelerometer. Prior to creating the channel I execute "DAQmx Configure TEDS" on the physical channel in order to read the TEDS information. What I can't figure out is how to find and read several of the accelerometer channel properties so I can verify the TEDS information is correct. Specifically, I cannot find properties for sensitivity, or sensitivity units. I looked in "DAQmx Channel" and "DAQmx Physical Channel" porperiy nodes but could not find sensitivity. Thanks for your help.

Hi,
I used to have the same problem. I spend a lot of time trying to find a property node or a VI in order to retrieve the information previously defined in the document, but unfortunately I wasn’t able to find one.

Get latest workflow instance programatically?

hi,
i am building sate machine workflow and when i upgrade the solution another workflow instance is created when workflow starts again.
now i want to get latest workflow instance problematically.
thanks,
gaurav.

Hi Jassik112,
You can use the following code get the latest work flow instance. Use bubble sort method.
public SPWorkflow GetTheLatestWorkflowInstance(SPListItem myitem)
SPWorkflowCollection ss = myitem.Workflows;
SPWorkflow[] sort = new SPWorkflow[ss.Count];
int k = 0;
foreach (SPWorkflow ghy in ss)
sort[k] = ghy;
k++;
SPWorkflow temp = null;
int i, j;
for (i = 0; i < sort.Length; i++)
for (j = i + 1; j < sort.Length; j++)
if (sort[i].Created < sort[j].Created)
temp = sort[i];
sort[i] = sort[j];
sort[j] = temp;
return sort[0];
Thanks,
Jack

Workflow Admin read only responsibility in EBS 11.5.10.2

Hi All,
I have a requirement to create a read only workflow administrator. For that I have done the below steps.
1. Created one permission set with Monitor Data.
2. Created one role and one grant for that role with the above selected permission set.
3. Then I have assigned the responsibility Workflow Administrator Web (New) to a user.
4. Assigned the above created role to to that user.
Then I tried to access the WF pages from that user, but still he is able to do all the activities that is possible by the Workflow Administrator Web Applications responsibility.
When I navigated to Workflow Administrator Web Applications-->Administration, Workflow System Administrator LOV is having value '*'. I changed that to 'Workflow Administrator Web Applications', and tried to access Workflow Administrator Web (New) from the above user.
Now no buttons are enabled for him. But in the Status Monitor, the user will be able to view only the Workflows owned by him.
But my requirement is to view all users workflow.
Can anyone guide me on how to achieve that.?
Also, I found that there is no significance for assigning Monitor Data permission. Please suggest me on that aspect also.
Hoping for youe valuable comments.
Thanks in advance.
Regards,
Charls K V

Hi Charls,
The note is also telling the same thing.:(
Then is there anyway to achieve my requirement.
Should be able to query everything as the admin does. But won't be able to perform any actions.
Looking forward for your valuable comments.I did manage to create the same using (How to Restrict Access to Data in the Workflow Monitor based on Item Types? [ID 559072.1]) but for specific item type (omit this step if you want to have access to all item types).
If you could share the steps you followed (in details) to implement the above, it would be helpful.
Please also review (How to enable Workflow Owned By LOV in Workflow Status Monitor for a User other than SYSADMIN [ID 1328447.1]) and see if it helps.
Thanks,
Hussein

Read Workflow Container Elements attributes

Hi,
I am using a F.M 'RH_GET_TASK_ATTRIBUTES' to get the attributes of the Workflow container elements.
But the above F.M does not show the element attributes that I create inside the Workflow Builer under Workflow Container Block and I dont select either Import or Export Properties.
Is there any F.M that reads ALL Workflow Container elements.

If you want to clear a single element, use a container operation and assign it to space. If you need to clear an internal table, create another internal table container element that is always empty. Then, inside the container operation assign the empty table to the table you want to clear.
Basically, you are doing this:
container_element = space. OR container_element = ' '.
container_internal_table[ ] = container_empty_internal_table[ ].

Read PDF Formatted Spool and write PDF File to Application Server

Hi Experts,
After ECC 6.0, HR-W2 and W2C Form Spools are getting generated in PDF format.
We have a requirement wherein we want to read the PDF Spool Programatically and write the PDF file to Application server (Using OPEN DATASET and CLOSE DATASET)

 i_spoolid = p_spono
 i_partnum = '1'
 IMPORTING
 e_pdf = pdf_data
* e_pdf_file = file
 EXCEPTIONS
 ads_error = 1
 usage_error = 2
 system_error = 3
 internal_error = 4
 OTHERS = 5.
* Modify the spool contents to prepare internal table
l_len = xstrlen( pdf_data ).
while l_len >= 1000.
 l_pdf_line = pdf_data+l_offset(1000).
 append l_pdf_line to l_pdf_data.
 add 1000 to l_offset.
 subtract 1000 from l_len.
endwhile.
if l_len > 0.
 l_pdf_line = pdf_data+l_offset(l_len).
 append l_pdf_line to l_pdf_data.
endif.
* GUI DOWNLOAD Works Fine
* Now pdf contents is ready , lets store in local PC
*CALL FUNCTION 'GUI_DOWNLOAD'
* EXPORTING
* filename = 'C:\Documents and Settings\Desktop\shital.pdf'
* filetype = 'BIN'
* TABLES
* data_tab = l_pdf_data.
OPEN DATASET p_file FOR OUTPUT IN BINARY MODE.
IF sy-subrc <> 0.
MESSAGE ID '00' TYPE 'E' NUMBER '398' WITH 'sy-subrc:' sy-subrc

CLOSE DATASET p_file.
IF sy-subrc <> 0.
MESSAGE ID '00' TYPE 'E' NUMBER '398' WITH 'sy-subrc:' sy-subrc
 ' Error closing file:'(Z04) p_file.
ENDIF.
Currently as you can see I have commented out GUI_DOWNLOAD Function Module, But it works perfect when I try to Download file to Local Desktop.
But when I try to pass the same Contents to Application server file and then try to open it by downloading file then it opens BLANK pdf file.
As per requirements I should be able to write the file correctly on Application server and If I dowload it from there it should open PDF file correctly.
Let me know if you require further details about the issue.

Workflow Activity "Lookup Value" returns An error occured while enumerating the filter using [//WorkflowData/customvalue]

I want to generate an Accountname using EmployeeID, FirstName and LastName via a workflow.
I'm using the Granfeldt Workflow Activity Library (https://fimactivitylibrary.codeplex.com/)
I'm using the FIM Powershell Workflow Activity (https://fimpowershellwf.codeplex.com/)
Steps:
Passing the EmployeeID, FirstName and LastName to the powershell Activity, generating a logonid based on logic.
Add-PSSnapin FIMAutomation
$EmployeeID = $fimwf.WorkflowDictionary.EmployeeID
$Forename = $fimwf.WorkflowDictionary.Firstname
$Lastname = $fimwf.WorkflowDictionary.Lastname
'logic creating a custom logonid here
==> This works
Returning data back to the workflow via that powershell script:
$fimwf.WorkflowDictionary.Add('NewAccountName',$newlogonid)
==> This works
Using Lookup Value Activity to read the Workflow data and update the [//Target/AccountName] fails.
This gives an error:
An error occurred while enumerating the filter 'string' .
(where string is the actual generated userid that I've got back from the powershell script. Example dab2563)
I tried with only [//WorkflowData], then this gives the error:
Index was outside the bounds of the array.
Any hints to solve this?
Kind regards,
David

The Lookup Activity is for looking up an object in the FIM Service. Seems like thats not what you're trying to accomplish.
For updating the target of the workflow, just use the built-in Function Evaluator. The Lookup WF was not built for that and it is failing because you have not specified a valid XPAth lookup filter, such as /Person[AccountName='BillG']

Urgent help needed in inserting data into a custom table in oracle WorkFlow

Hi
I am trying to get data from the WF and insert into a custom table..
I read that workflow procedures WONT allow commits...
Oracle Workflow will not support autonomous commits in any procedure it calls directly. If you need to perform commits, then embed your SQL in a subprocedure and declare it as an autonomous block. This subprocedure must be capable of being rerun. Additionally, note that Oracle Workflow handles errors by rolling back the entire procedure and setting its status to ERROR. Database updates performed by autonomous commits cannot be rolled back, so you will need to write your own compensatory logic for error handling
Have anyone did this..
Please give me some idea ...It is urgent
I am getting data using getitemattribute..and try to insert it into a custom table
thanks
