Collect Data... how to mark task as completed

Posted By:      Posted Date: October 25, 2010    Points: 0   Category :SharePoint

I am using the Connect Data workflow action to create a task for a group of people. If one of those people completes the task, I need to somehow prevent others from editing the task and completing it themselves.

Is there a way to show on the "Edit Task" screen that the task has been completed and who completed it? As a basic start I tried adding the "@Editor" value to the screen manually, but it doesn't show up. In a perfect scenario I want something that behaves like the OOB Approval Workflow Tasks: if a task has been completed and another user tries to edit it, a message will pop up on the screen saying "Task completed by...".

I could just make a task read only after it has been completed, but users still try to jump to the "Edit Task" screen directly from their Outlook email notification. They would receive an Access Denied error, which doesn't really make sense. The same problem would happen if I deleted the task entirely: if people click on their "Edit Task" button in Outlook they would go into no-man's land.

Collect Data from a user task error

Hello, I am a new admin and I'm hoping you can help. I have used the Collect Data from a user Action in a workflow in Designer. I get no errors in saving or publishing. My workflow works find and sends me the task assignment as an email when I test. However, I then run into three problems which (together or separately) prevent me from moving forward in the workflow. 1) When I click the "edit task" button located in the task email, my entire Outlook locks up and must be restarted. (I am using outlook 2007 and Sharepoint Foundation 2010) 2) The email says in step 3 to use the "Open the Task" button to mark the task complete. I cannot find this button anywhere. 3) When I go directly into the task, I can view it but I can find no way to "complete" the task without editing it directly. This gives me an error window that says, "Type 'Microsoft.SharePoint.WebControls.SPDataSource' does not have a public property named 'UseServerDataFormat'. "

Selecting a Task List in Sharepoint Designer 2007 while setting up "Collect Data from User"

When using Sharepoint Designer 2007 to Collect Data from User the task list cannot be selected.  Instead the Task list that is defaulted is the most recently created Task List.  How can I select a specific Task list to associate with"Collect Data from User"?

Modify User in Collect Data from User Workflow


I've created a workflow with a Collect Data from User action that emails a Group when the task is created. Once the task is claimed by an individual, the Assigned To column in the task list is updated to display that person's name but once the task is completed the email variable for the action is not updated and the group is emailed instead of the person listed as Assigned To.

So the question is this: Is there a way to update the user varialbe in the workflow task once the task is completed, or would I need to build my own workflow and use the Send Email action?

How do I add two XML tasks to a Data FLow task?

I am new to SSIS and am developing a package which takes input from an XML file and then populates an existing SQL table with these records.  However, this is a very large XML file.  I keep getting an Out of Memory exception.  (This file is 210 MB)!  So what I tried doing was separating this XML file into 8 smaller files.  Now, I can successfully load data from these smaller files one at a time.  But how can I do all of them in the same package?  I connected two XML tasks to the Data Flow task and get the error below.  I also increased my timeout and number of errors to no avail.  Advice? Error: 0xC002F304 at XML Task 1, XML Task: An error occurred with the following error message: "Exception of type 'System.OutOfMemoryException' was thrown.". Task failed: XML Task 1 Warning: 0x80019002 at zSkywardEnrollment: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (1) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "Exception of type 'System.OutOfMemoryException' was thrown.". Task failed: XML Task SSIS package "

How to detect that a Data Flow Task has failed (from inside a custom componet)

Hi, in the PostExecute Method of a custom component i would like to check if the Data Flow Task has been failed. Is that possible? Also it would be great to be able to check if this custom component already got all data or has been marked as "green".  Thanks, Dennis

Data flow task with multiple destinations randomly hangs

I have a package whose control flow consisting of a single data flow task with multiple destinations continues to hang at random locations.  The data flow task is fairly simple: - One OLE DB source (one query of selecting about 10 fields from one table) - 9 lookups that serve basically as left joins to capture which data "drops off" (does a row redirect on on lookup errors to an "error flow") - Two destinations: one the captures all the data that doesn't drop off from the lookups, and another to capture the data that does drop off; these write to two tables unrelated to each other, and unrelated to any of the tables I'm reading from I have tried the following: - Changed one or both destinations from OLE DB to flat file -- still randomly hangs - Removed both destinations altogether -- this always suceeds.   - Removed destination A and leave destination B -- this always succeeds - Removed destination B and leave destination A -- this always succeeds I took great care in making sure I get no warnings when the package runs, even resolving the unneeded column warnings, and the duplicate keys on all my lookups, but it still hangs. However, once I give up and stop the package, the following error is thrown (among others that appear to be a byproduct of the root issue): Error: 0xC02020C4 at Data Flow Task, OLE_SRC AP12 [1]: The attempt to

C# newbie stuck - trying to access column data in a SharePoint list in an SSIS script task

Hello, I'm sure this is the simplest question but I can't figure it out, even with Google's help. I am trying to stumble through some C# code in an SSIS script task and I am frustrated that I can't figure out how to do the easiest things.  I eventually want to find data in a column,and then use another list as a lookup to replace that value with another where the existing value matches a value in the lookup list.  So, the data in my (multiple choice) column might be "apples; bananas" and in another list I have a row that contains two columns, the first holding the value "Apples" and the second containing "Red Delicious" and my original column should read: "Red Delicious; bananas." But, alas, I can't even figure out how to see the data that is in a column. Here is my code: /*<br/> Microsoft SQL Server Integration Services Script Task<br/> Write scripts using Microsoft Visual C# 2008.<br/> The ScriptMain is the entry point class of the script.<br/> */<br/> <br/> using System;<br/> using System.Data;<br/> using Microsoft.SharePoint;<br/> using Microsoft.SqlServer.Dts.Runtime;<br/> using System.Windows.Forms;<br/> using Microsoft.SharePoint.Utilities;<br/> <br/> namespace ST_08becda4c05c49cd9f30ea76110076cd.csproj<br/> {<br/> [

Share Point Designer 2007 Workflow (Sequential) - multi-collect data from user

I am currently building a multi-step workflow using ShrePoint designer for MOSS2007. I am getting a bit confused as to if I have an error or if I am doing something incorrect. Here is what I have going. My workflow consists of something similar to the following New document comes in, a collect data from user routine is ran and assigned to a reviewer. My understanding when I create a collect data from user WorkFlow step is any data I request is saved in the "Tasks" list. Therefore I need to grab the workflow task ID in order to later lookup what the reviewer submitted... I understand this...   However, I have one more collect data from user workflow step and I have one more item to collect. Even though this is a brand new collect data from user workflow step - does the collected data still go into the "Tasks" list? In other words, if I have two steps in a workflow and both of these steps are "collect data from user", does the data from both steps go into the same "Tasks" list?  I could see how this might be possible as long as the Task list columns contain all the items for all the different "collect" data from user steps.  I don't see two different Tasks lists representing or named "Reviewer" or "Final" or anything, so I assume the items are all in "Tasks"   However..

Error: The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registe

Hi, I am trying to create a simple BI Application for SSIS. In Visual Studio 2005 I just get a Data Flow Task from the toolbar and add it to the project. When I double click it I get the following error: The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer. Then when I try to delete it it gives this other error: Cannot remove the specified item because it was not found in the specified Collection.  I am creating this application in an administrator account in this computer, so I doubt the problem is related to permissions. I am running SQL Server 2005 and Visual Studio 2005 in WinXP Tablet PC Edition. Any suggestions why this is happening and how to fix it?

Populate a Data Flow Task's variables with values from a .dtsConfig file?

I have an SSIS Project to import exchange rates from an XML file into SQL. The project works when I have certain values hard-coded into variables, such as the URL of the XML File, proxy username and passwords etc. I decided to put in a .dtsConfig file, and have it update the values of the variables in the data flow task. So, one of my SSIS Packages in this solution is called ECBDailyRates.dtsx. It contains one control flow, which is a data flow task. The data flow task is a script task which does some XPATH on an XML file, and then provides outputs to an OLE DB Destination, which in turn puts the data into a table in SQL. That much worked before I put in the dtsConfig file. There are a few variables declared inside the data flow task, such as; PricesXMLUriDaily, String ProxyAddress, String ProxyAddressPort, Int32 etc. etc. These are now being updated from the dtsConfig, which is below. It was my understanding that SSIS would run through the config, and update any of the variables as required, and then run my data tasks. However when SSIS runs my script task, none of the variables have been populated, and so it falls over... as it were :) <?xml version="1.0"?> <DTSConfiguration> <DTSConfigurationHeading> <DTSConfigurationFileInfo GeneratedBy="...." GeneratedFromPackageName="dim_Institution" GeneratedFromPackageID="

Can't make parameterized query work in data flow task


I have an OLE DB source in a data flow task.  The connection is pointing to a SQL Server 2008 instance.  My SQL works fine when I click the preview button.  Now I need to make it parameterized by adding a question mark in my where clause.  After doing so & clicking the Parameters button, I get the error described in this post .  When I try to do what's described therein to correct the problem (click the "build query" button), I get the error "The PIVOT SQL construct or statement is not supported."

I can't make this query an expression; it's simply too complex to maintain that way (besides, just pasting it into an expression builder window and trying to evaluate as is doesn't work - can't evaluate).

So the question is, how do I parameterize a query?  And why does SQL here work so radically differently from SQL in an execute SQL task?

Writing XML data from URL to Object in SSIS Script Task

I have this URL where there is XML data. I have to extract that data from URL and dump it into DW table. I am using SSIS Script Task for that.

This is how the data looks like:
<cname>United Arab Emirates Dirhams</cname>
<cname>Afghanistan Afghanis</cname>
<cname>Albania Leke</cname>

This is the code i'm using to load it into some Object type or something. But i dont know how to do that.

public void Main()
   String URLString = "http://www.xe.com/dfs/datafeed2.cgi?beeline";
   XmlDocument doc = new XmlDocument();
   XmlTextReader reader = new XmlTextReader(URLString);

Collect data from a User - Validation Bug




I use the action "Collect data from a User". I add a new field of the type Choice, the next step I write two choices:




and configure it:


Default value is blank
  Display as: Radio Buttons
  uncheck Allow Fill-in choices
  uncheck Allow blank values


Click Finich button


When the task is created I need to choose among Approved or Rejected, however if it be not chosen any alternative the validation doesn't work.


If I have a field text the validation works perfectly.


Is there a bug in validation form when the field is a "Choice type" ?


Please help-me.
