System Center Service Manager HTML email notification

When you are using  HTML template, now the formatting is stripped; cause a line break should be written as <br /> and not with the enter key on the keyboard.
The solution to this is to use <pre>

Just add to your incident description in html:
<pre>$Context/Property[Type='WorkItem!System.WorkItem']/Description$</pre>

System Center Service Manager delete the items and reset

After Installing new Service Manager server to delete test incidents, and reset IR number follow this instruction: 

Install the SMLets database on the SCSM server, 
open the Powershell  to removal of Incident events:

Import-Module SMLets
Get-SCSMObject -Class (Get-SCSMClass -Name System.WorkItem.Incident$) | Remove-SCSMObject -Force -Confirm

Login to the Service Manager database (SQL Server):

select * from AutoIncrementAvailableRange

Select MT.TypeName,MT.ManagedTypeId,MTP.ManagedTypePropertyName,MTP.ManagedTypePropertyID,AIAR.FirstAvailableValue

from ManagedType as MT, ManagedTypeProperty as MTP, AutoIncrementAvailableRange as AIAR

where MT.ManagedTypeId = AIAR.ManagedTypeId and MTP.ManagedTypePropertyId = AIAR.ManagedTypePropertyId

All project number, is according to the table in the last line of data coding, that is to say, if you want to make Incident ID digital restart from the beginning of 1, change:

update AutoIncrementAvailableRange

set FirstAvailableValue = 1 

where ManagedTypeId = 'F59821E2-0364-ED2C-19E3-752EFBB1ECE9' and ManagedTypePropertyId = '28B1C58F-AEFA-A449-7496-4805186BD94F'
