Creating (or Editing) an Object From a Template Programmatically

@Scott - the most common case for that error message happens when you are applying a template which has an action log entry defined in it. That doesnt work because each action log entry has a unique ID. If that ID is used once for a particular incident then it will fail the next time you try to add an action log entry to a different incident with the same action log entry ID.

Travis, how do you use this to apply an Incident template to an existing Incident object or type projection, I always get an error

Microsoft.EnterpriseManagement.Common.DiscoveryDataLifetimeDependencyException: A discovery data item was rejected because the item is already bound to another Membership relationship.

I am adding a 'WorkItemAssignedToUser' to the incident type projection and commiting it

I then try to apply the template (which has some fields changed on it such as the urgency etc) and get this error

Any ideas

Thanks

Seems to me I'm somewhere near

New-SCSMObject with Service Request Template — Fri, 23 Dec 2011 09:57:59 GMT

Travis,

How to perform this with powershell with Service Requests?

I'm trying to put different Ids for TemplateId in New-SCSMObject. Still didn't succeeded.

=====script 1=====

$sr_class = get-scsmclass -name System.WorkItem.ServiceRequest$

$sr_prior = Get-SCSMEnumeration -Name ServiceRequestPriorityEnum.Medium

$sr_urg = Get-SCSMEnumeration -Name ServiceRequestUrgencyEnum.Medium

$title = "TEST SR Title"

$templ_id = Get-SCSMObjecttemplate | ? { $_.displayname -match "<blah-blah-blah>" }

New-SCSMOBject -Class $sr_class -PropertyHashtable `

(@{`

Title = $title; `

Urgency = $sr_urg; `

Priority = $sr_prior `

}) -Template $templ_id

=====script 1=====

gives an error

=====out 1=====

New-SCSMObject : Only a template targeted at a class can be applied to a single object.

At D:\work\test2.ps1:21 char:15

+ New-SCSMOBject <<<< -Class $sr_class -PropertyHashtable `

+ CategoryInfo : NotSpecified: (:) [New-SCSMObject], InvalidOperationException

+ FullyQualifiedErrorId : System.InvalidOperationException,SMLets.NewSMObjectCommand

=====out 1=====

And this one doesn't apply the template

=====script 2=====

$sr_class = get-scsmclass -name System.WorkItem.ServiceRequest$

$sr_prior = Get-SCSMEnumeration -Name ServiceRequestPriorityEnum.Medium

$sr_urg = Get-SCSMEnumeration -Name ServiceRequestUrgencyEnum.Medium

$title = "TEST SR Title"

$templ_id = (Get-SCSMObjecttemplate | ? { $_.displayname -match "<blah-blah-blah>" }).id.tostring()

New-SCSMOBject -Class $sr_class -PropertyHashtable `

(@{`

Title = $title; `

Urgency = $sr_urg; `

Priority = $sr_prior; `

TemplateId = $templ_id `

})

Hi Travis,

I'm trying to apply a Change Request template that contains activities. I notice that the activities that get created after applying the template don't have the correct prefixes. Do I need to iterate through all the related items and make sure they have their prefixes set?

Thanks!

@Rob - No problem. Hang in there. Check out this blog post:

blogs.technet.com/.../using-the-sdk-to-create-and-edit-objects-and-relationships-using-type-projections.aspx

Especially example #5.

@Travis - thanks for bearing with me. I think the problem here is my luck of understanding in this particular area. I don't know how to create a new incident (or other class) using an emop instead of a cemo, if you have a blog example perhaps you could point me at it?

I've gotten around it for now by hard-coding the required values into the code.

If you have a cemo and you want to apply a template to it you need to have a template which has a class as the TypeID instead of TypeProjection for the TypeID.

Rather than use a cemo can you use an emop as above?

@Travis - thanks - I don't really understand how to apply that (to my cemo), I'll do some more research...

@Rob - Sorry I forgot for some reason we dont have a CreatableEnterpriseManagementObjectProjection class. You just need to do it like the example above:

//This is how you apply a template to a new object projection you want to create:

EnterpriseManagementObjectProjection emop = new EnterpriseManagementObjectProjection(emg, mpt);

emop.Overwrite();
