how to write a trigger to prevent a profile from deleting a change request

Hello Guys
am new to Apex code. I would like a trigger to prevent members of a profile from deleting  a change. I have come up with this code but i get an error. Could you help me refine it.
trigger RestrictDelete on BMCServiceDesk__Change_Request__c (before delete) {

String ProfileId = UserInfo.getProfileId();  
for (Change_Request a : Trigger.old)      
            
IF(ProfileId!='profileid'))
{
     a.addError('You cannot delete this record!');
     
            }
}

HI Jackline,
Try with below code it wil help !!
  
trigger RestrictDelete on BMCServiceDesk__Change_Request__c (before delete) {
	String profileName=[SELECT id,Name FROM Profile WHERE Id =:UserInfo.getProfileId()].Name ;  
	for (Change_Request a : Trigger.old){      
		If(profileName=='Your ProfileName')){
			a.addError('You cannot delete this record!');
		}
    }
}
if you want you can store the profile name in a custom lable .
String profileNameDynamic=System.Label.LabelName;
If(profileName==profileNameDynamic)

Let me know if it helps !!
Thanks
Manoj

Jackline,

Can I ask why a trigger is needed for this instead of just removing the delete privlege at the Profile-level (admin task)? If the limitation is that you cannot edit the standard Profile provided by BMC, then I would recommend cloning the Profile in question to create a custom version of the standard Profile and use the custom version for all users needing the access instead writing code to address this need. Hope this helps.

Thanks,
David

@David removing the delete privilege also removes the modify all permission which I want to maintain. I want the users in the profile to be able to do everything else except delete the changes.

@Jackline makes sense. Unfortunately code may be your only option and in that case, Manoj's code above looks like it should work.

@Jackline Another discussion I was just participating in has some more code that I know works to prevent deletion of Accounts, so perhaps it will help if Manoj's solution doesn't work. See https://developer.salesforce.com/forums/ForumsMain?id=906F0000000MH1YIAW
