Question on delayed tasks in RequestCenter

In a specific task plan, we have two tasks that can be completed concurrently but we need one task to start a few minutes after the other.  Using the scheduled start feature, we can manually set a date and time in a dictionary field, which seems to produce the desired effect, but we would like to populate the scheduled start date automatically.  It should be populated with 2 minutes after the service delivery starts.
After struggling with this for a little bit, I've come to the conclusion that the ISF rules are only executed when someone is actually viewing the form in RequestCenter.  For example, if I create an ISF rule to populate the date and time of the schedule start field when the moment is service delivery, someone actually has to look at the form during the service delivery moment in order for the ISF rule to execute.  Does this sound correct?
Is there a way to tell the system that the scheduled start date for the task should be 2 minutes after the precceding task starts or 2 minutes after the plan starts to execute?

You app's threads will all suspend when the app suspends. If you need to continue running in the background you will need to register a background task.
BackgroundUploader and Downloader are the best ways to accomplish uploading and downloading in the background.
For other functionality in the background it depends on what specifically you need to do. Background processing is deliberately limited, but you can create Background Tasks for specific purposes. As hereafter suggested, please see

    Hi:
    I have tried to get a scheduled task to work without any luck.  I am referencing a date/time field on the form and the task goes to "Scheduled", but never moves to "Ongoing".
    I've opened a case with support, but was wondering if anyone has gotten this to work.

    We just went through this too. If the plan is fairly complex, and has allot of conditional tasks you will have difficulty.
    The explanation I got from Shweta is that the calculation that determines the OLAs before my scheduled task was to start looks at ALL the potential tasks and combines them, essentially saying the duration is much longer than what you think it should be, ie the sum of all potential task OLAs, not just the tasks that became active.
    Bottom line if your scheduled date is with

  • List of delayed tasks in MS Project 2010

    Hi Experts !!
    Is there a way out to find all the delayed tasks in a project.
    Also, a list of task either running/continuing or starting in between two dates.
    TKP86

    Hi,
    "Late" implies a comparison between two dates. One is the finish date of the task; do you mean current date is the other one?
    In other words, are you looking for tasks with a planned finish date before today, but not yet finished?
    That implies you will not really track your project, meaning that when a task's plan changes, that will impact the planning of other tasks so your planned finish date could be moving al the time.. I have the impression that in your mind, the original plan
    will always be "the plan". And the utility of a baselin is that it is an immovable copy of that original plan - such that you can enter actual start/finish dates when reality strikes..
    By all means, you could set a formula in a flag field to show the definition of Late as I guess you have in mind:
    iif([% Complete]<100;IIf((projdatediff([Finish];Now())>0);No;Yes);No)

  • Question of displaying Task Flow Region in Master-Details pattern

    We have a master-details page. There is a region on the details pane along with other widgets and the content of that details pane including the region depends on the row selection on the master table list.
    The first time page loads with no row selection on master table so this details pane displays nothing. When I select one row on the master table and the details pane and its region can display data of the row in master table properly.
    After several selection, I navigate to another page and then go back to this master-details page again, it automatically selects the row which was selected last time. And in the details pane, the region whose content was created basing a task flow call cannot display corresponding data of the default selected row while other widgets in the details pane can display corresponding data properly.
    The reason of having this problem is the region's parameter is generated before the selected row is determined. When the task flow call in page definition is parsed, the parameter of this task flow call is created before component binding of the master table. It means when the task flow call is parsed and generating the parameter, the ADF page believes there is no row selection of the master table because the component binding is null at that time.
    So my question is how to make the this task flow call for that region create the task flow call parameter after the component binding of the master table? Or is there any way to force a refresh of the region/task-flow-call after the render of response? Or is there anyway to disable this "auto-select" on the master table after navigating to other page?

    Edited by: user790224 on Sep 6, 2012 4:16 PM

    The reason we are using master-details patter here is it is designed in that way and the region is displaying the data of a selected row there.
    There is no master-details relationship on model layer. But the content of the region is from the result of several other Java API calls which call the task-flow from an external component.

  • Question on WF_EXTSRV - Task (Transporting this task)

    Good day,
    I have implemented a workflow that calls a Webdynpro application.  I have done the required configuration in WF_HANDCUST and WF_EXTSRV (and also generated the task). The process has been tested successfully.
    My question is on moving this developement to the rest of my landscape (to QAS, PRD).
    The task that is created in WF_EXTSRV is w.r.t. to the Logical system of the Dev client and will not work with QAS, PRD. Can you please advise how we can move such developements.
    Also WF_HANDCUST are system specific configuration. Is this a config that Basis takes care of in your systems (Dev, Qas, Prd) ?
    Appreciate your help guys!
    Rgds, Liz

    All,
    Resolved this. Here is the solution -
    It came down to bad/missing entries in table SWLWPTSSID. This is the table that links the web service maintained in WF_EXTSRV with the workflow task. As it is a client-dependent setting, when you transport the task and webservice you also need to adjust this table using transaction SM30.
    Cheers, Liz

  • Best practice question for Bounded task flows

    We are new to Jdeveloper/ADF and I was wondering if we should always try to use a bounded task flow for our applications... is this considered the best way to develop an app? even the small single page ones?
    Thanks in advance.

    Hi,
    let me turn teh question around: How many tools do you have at home beside of a hammer ? In other words, its the problem you need to solve (and use cases are problems) that should determine the use of bounded task flows and its granularity. Note that for each use case the bounded task flow makes a good candidate for delivering it. Doesn't mean that every single page needs to go into its own task flow. For general bounded best practices have a look here

  • Question about show task's info

    hi
    i try to implement netweaver ce ehp1's bpm amd had some question.
    how to access tables of bpm's data base? because i want to show the history or info about the process, such like who sign, how long the task spand or how many job should do.
    if i should create another db, such like caf systom, to record the message, how to sync data when i have to close end the process from database(back)?
    thank you.

    Hi Vic,
    I am sorry to say but its not possible to extract data out of BPM internal tables to generate a custom report (KPI) in the current version. This functionality is limited to the Process list viewer and the data is stored internally and there are no APIs available to access the same. You will be able to see some new features related to this in the upcoming Netweaver 7.2.
    If you want to achieve the said functionality, then you have to go for creating a custom EJB functon to record details at each step and then use this for creating the report.

  • OIM: Question on Process Task configuration

    Hi OIM guru,
    I have a process form and a child form. I have a process task that gets triggered when a child entry is added. My question is, is there a way to avoid duplicate child table entries? For example, a user can have groups g1, g2 ... etc. How do we configure such that the admin cannot pick the same g1 once it is already added. When clicked on the lookp for groups all groups will show but is there a way to not let an existing group to be added again?
    Thanks

    You can't. Don't give the admin that functionality. Create a seperate object that manages the groups and on your provisioning side, do your checks to see if it already exists before adding another.

  • TimerTask - elegant way to decide whether to execute a delayed task

    We want to schedule a regularly recurring task that runs only if
    it is not delayed (due to some other processing load on the system).
    If the task is delayed in any way we want it to not execute.
    The API documentation for TimerTask shows the following:
       public void run() {
           if (System.currentTimeMillis() - scheduledExecutionTime() >=
               MAX_TARDINESS)
                   return;  // Too late; skip this execution.
           // Perform the task
       }It is MAX_TARDINESS that is the issue. Without subclassing TimerTask to take an argument so the task "knows" what MAX_TARDINESS is (the period , which is the time between recurrences), is there any other way a TimerTask knows what its period is?
    It looks to me like Timer can call a schedule() method with a period argument , but the actual TimerTask doesn't know what its own period is. Am I reading that correctly?

    For anybody interested I will post a solution demo here:

  • Question about AXF Task List Web Tool

    On the Task List Web Tool, i want to display the comments oan each task on this page as another column. I'm running the 10g version on the AXF application.

    HI,
    Customizing the Task List
    You can customize the column headers or search for required tasks by clicking on Customize Table Header. The option allows you to specify the columns to be showed in the list table, to provide the sorting order, and to set the page size. The sorting order could be complex with option to provide multiple columns for sorting and the order (ascending/descending) for each of them.
    To create a custom query and search for tasks:
    1.In the Task List page, click Customize Table Header.
    In the Construct a Custom Query form, specify the search criteria by specifying any of the following values.
    2.Enter the task name. You can use the * character at the start or the end of the name.
    3.Enter the task ID. Separate multiple values using comma.
    4.Select the check box against the Administration and Working state of the task.
    5.Enter any comment. You can use regular expression.
    6.Enter the priority range.
    7.Enter the Assignee, Owner, or Claimant names.
    8.Specify the completion due date range.
    9.If required, select the Include tasks with no completion due date check box.
    10.Click Apply.
    All tasks that match the specified criteria are displayed in the Task List page.
    To customize the table header:
    1.In the Task List page, click Customize Table Header. The Construct a Custom Query form appears.
    2.In the View form, select the columns that you want to view in the Task List page.
    3.Select the Preserve Search Criteria check box to retain these details for the current session.
    4.Select the maximum number of search results that should be displayed on the page.
    5.Select the number of rows that should be displayed in the page.
    6.Click Apply.
    The view in the Task List page is updated based on the current settings.
    Using this option you can set the completion due date
    Hope this information will help you solve the issue.

  • SAP CS 8.0 - question to parallel tasks in one job chain

    Dear all,
    I have a question about job chains in SAP CPS/Redwood
    We have a job chain like this:
    Job 1
         Job 1.1
                   Job 1.1.1
                   Job 1.1.2
         Job 1.2
                    Job 1.2.1
    The Jobs 1.1.1 and 1.1.2 should start  when the Job 1.1 is compled and don't have to wait until Job 1.2 is complete.
    How could I release it in Redwood in one job chain? Should I use a precondition in the job definition of 1.1 and 1.2?
    Thank you for your help.
    Best regards,
    Hans

    Assumptions :
    Job 1.1.1 and Job 1.1.2 are running in parallel.
    Job 1.1, job 1.2 are also running in parallel.
    Chain A -
    Step 1 - Job 1.1
    Step 2 - Job 1.1.1, Job 1.1.2 (these both will start as soon as Job 1.1 completes)
    Chain B -
    Step 1 - Job 1.2
    Step 2 - Job 1.2.1
    Chain C
    Step 1 - Job 1
    Step 2 - Chain A, Chain B (Chain A and Chain B will start as soon as Job 1 completes).
    Submit Chain C.
    Preconditions are usually  used to check the timewindow, for example , if you want to execute a step in a job chain, only if it is a Friday.
