How to Add a Step to an Operating System Deployment Group

Article
10/04/2022

You add a step (an action or a group) to an operating system deployment task sequence group, in Configuration Manager, by adding the step to the SMS_TaskSequenceGroup.Steps array property.

To add a step to a task sequence group

Set up a connection to the SMS Provider. For more information, see SMS Provider fundamentals.
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.
Create the task sequence step. For an example of creating an action step, see How to Add an Operating System Deployment Task Sequence Action.
Add the step to the SMS_TaskSequenceGroup.Steps array property.
Reorder the step within the array property as necessary. For more information, see How to Re-order an Operating System Deployment Task Sequence

Example

The following example method adds a command-line action to a task sequence group.

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

Sub AddStepToGroup(taskSequenceStep, group)     

    Dim steps   

    ' If needed, create a new steps array.  
    If IsNull(group.Steps) Then  
        steps = Array(taskSequenceStep)  
        group.Steps=steps  
    Else  
        ' Resize the existing steps and add step.  
        steps= Array(group.Steps)  
        ReDim steps (UBound (group.Steps)+1)   
        group.Steps(UBound(steps))=taskSequenceStep   
    End if   

End Sub

public void AddStepToGroup(  
    WqlConnectionManager connection,   
    IResultObject taskSequence,   
    string groupName)  
{  
    try  
    {  
        // Get the group.  
        List<IResultObject> steps = taskSequence.GetArrayItems("Steps"); // Array of SMS_TaskSequence_Steps.  

        foreach (IResultObject ro in steps)  
        {  
            if (ro["Name"].StringValue == groupName && ro["__CLASS"].StringValue == "SMS_TaskSequence_Group")  
            {  
                IResultObject action = connection.CreateEmbeddedObjectInstance("SMS_TaskSequence_RunCommandLineAction");  
                action["CommandLine"].StringValue = @"C:\donowtingroup.bat";  
                action["Name"].StringValue = "Action in group " + groupName;  
                action["Description"].StringValue = "Action in a group";  
                action["Enabled"].BooleanValue = true;  
                action["ContinueOnError"].BooleanValue = false;  

                // Add the step to the task sequence.  
                List<IResultObject> array = ro.GetArrayItems("Steps");  

                array.Add(action);  

                ro.SetArrayItems("Steps", array);  
                taskSequence.SetArrayItems("Steps", steps);  
                break;  
            }  
        }  
    }  
    catch (SmsException e)  
    {  
        Console.WriteLine("Failed to create Task Sequence: " + e.Message);  
        throw;  
    }  
}

The example method has the following parameters:

Parameter	Type	Description
`connection`	- Managed: `WqlConnectionManager` - VBScript: SWbemServices	A valid connection to the SMS Provider.
`taskSequence` `taskSequenceStep`	- Managed: `IResultObject` - VBScript: SWbemObject	- A valid task sequence (SMS_TaskSequence) that contains the group.
`groupName` `group`	- Managed: `String` - VBScript: `String`	The name of the group that the command-line action is added to. This is obtained from the `SMS_TaskSequenceGroup.Name` property.
