Currently, I'm working on the parent-child relationship on the lead object. So, we are restricting users to convert only master lead & then top 20 related leads will be converting as contacts to the same account.

And we want to update existing unwanted related leads to mark the status as not required & update other fields too.

public class RelatedContacts
    public Static List<Contact> Relatedcontacts = new List<Contact>();
    public static integer count=0;
    public Static List<Lead> OtherLeads = new List<Lead>();
    public static void LeadConvertion(Map<Id,Id> RelatedLeads) 
        List<Database.LeadConvert> converts = new List<Database.LeadConvert>();
        String convertedStatus = [SELECT MasterLabel FROM LeadStatus WHERE IsConverted = TRUE LIMIT 1].MasterLabel;
            for(Lead Ls:[Select id,Parent_Lead__c from lead where Parent_Lead__c=:RelatedLeads.keyset()])
                If(Ls.Parent_Lead__c <> null && count <20)
                    Database.LeadConvert lc = new Database.LeadConvert();
                    count =count+1;
                if(Ls.Parent_Lead__c <> null && count >=20)
                    //Lead lss=new lead();
                    Lead ll=new Lead(Id = Ls.Id);
                    //ll.Status='Not Visible';
            Update OtherLeads;
        Database.convertLead(converts, false);

My Problem is: when I try to convert a lead I'm getting this error.

5:28:05.55 (2030963109)|DML_END|[1738] 05:28:05.55 (2031063455)|EXCEPTION_THROWN|[1738]|System.DmlException: Update failed. First exception on row 0 with id 00Q0p000001FrJvEAK; first error: CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, UpdateTerritories: execution of AfterUpdate

  • It is lookup field to the lead object

Your issue is on this line:


Based on your comments, Parent_Lead__c is a lookup field which can contain only Id values and that you are trying to assign an empty string to it, which is resulting in the error.

If you are creating a new record out there, you don't need to assign anything to this field, you can simply leave it as is without the need of setting a value out there. If you are re-parenting then you can assign a null value to the field.

  • I have updated the code. But it's taking too much time to convert even I don't know whether it's working or not

  • @Pavantej That will classify as a different question based on the format of SFSE. You may like to open a new one with all the applicable details.The answer to the current question was to address the specific issue that you were having.
