How to Remove a Step from an Operating System Deployment Group

 

Updated: November 1, 2013

Applies To: System Center 2012 Configuration Manager, System Center 2012 Configuration Manager SP1, System Center 2012 R2 Configuration Manager

In System Center 2012 R2 Configuration Manager, you delete a step (an action or a group) from an operating system deployment task sequence group by deleting the step from the group's list of task sequence steps.

To remove a step from a group

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Get the SMS_TaskSequenceGroup object that you want to add the step to. For more information, see How to Create an Operating System Deployment Task Sequence Group.

  3. Remove the action from the SMS_TaskSequenceGroup.Steps array property.

Example

The following example method removes an action from a task sequence group.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

Sub RemoveActionFromGroup(taskSequenceGroup, actionName)

    Dim i

    If taskSequenceGroup.SystemProperties_("__CLASS")<>"SMS_TaskSequence_Group" Then
        wscript.echo "Not a group"
        return
    End If

        Dim newArray
        Dim actionStep

        newArray = Array(taskSequenceGroup.Steps)
        ReDim newArray(UBound(taskSequenceGroup.Steps))

        i=0
        for each  actionStep in taskSequenceGroup.Steps
            If actionStep.Name = actionName and _
              actionStep.SystemProperties_("__SUPERCLASS") = "SMS_TaskSequence_Action" Then
                 ReDim preserve newArray(UBound(newArray)-1) ' shrink the Array
            else
               wscript.echo actionStep.Name
               Set newArray(i)=actionStep ' copy it
               i=i+1
            End If   

         Next

         taskSequenceGroup.Steps=newArray

 End Sub
public void RemoveActionFromGroup(
    IResultObject taskSequenceGroup, 
    string actionName)
{
    try
    {
        if (taskSequenceGroup["__CLASS"].StringValue != "SMS_TaskSequence_Group")
        {
            throw new System.InvalidOperationException("Not a group");
        }

        List<IResultObject> groupSteps = taskSequenceGroup.GetArrayItems("Steps");
        IResultObject actionFound = null;
        foreach (IResultObject actionStep in groupSteps)
        {
            if (actionStep["Name"].StringValue == actionName && actionStep["__SUPERCLASS"].StringValue == "SMS_TaskSequence_Action")
            {
                actionFound = actionStep;
                break;
            }
        }

        groupSteps.Remove(actionFound);
        taskSequenceGroup.SetArrayItems("Steps", groupSteps);
    }
    catch (SmsException e)
    {
        Console.WriteLine("Failed to remove action: " + e.Message);
        throw;
    }
}

The example method has the following parameters:
