I have removed the AutoCreateAccountsCaseSI trigger now as it was preventing other triggers from 'triggering'!

Effectivly, this is what i have:

1. Opportunity stage changed to 'Test Closed Won' - a new 'Service Agreement' is created.

trigger AutoCreateSA on Opportunity (after insert , before update)
{
    if(!StaticClass.flag)
    {
        List<Service_Agreement__c> listSA = new List<Service_Agreement__c>();
        
        for(Opportunity o : trigger.new)
        {
            if(Trigger.isUpdate)
            {
                if(o.StageName == 'Test Closed Won' && o.StageName != trigger.oldMap.get(o.Id).StageName)
                {
                  listSA.add(new Service_Agreement__c(
                  name = o.Name + ' - ' + o.Service_Type2__c,
                  Related_Account__c = o.accountid,
                  Related_Opportunity__c = o.id,
                  BD_Owner__c=o.OwnerId,
                  Primary_Contact__c = o.Primary_Opportunity_Contact__c
                  ));
                }
            }
            if(Trigger.isInsert)
            {
                if(o.StageName == 'Test Closed Won')
                {
                  listSA.add(new Service_Agreement__c(
                  name = o.Name + ' - ' + o.Service_Type2__c,
                  Related_Account__c = o.accountid,
                  Related_Opportunity__c = o.id,
                  BD_Owner__c=o.OwnerId,
                  Primary_Contact__c = o.Primary_Opportunity_Contact__c
                  ));
                }
            }
        }
    
        if(listSA.size() > 0)
        {
            insert listSA;
        }
        StaticClass.flag = true ;
    }
}

 2. Once this is created - a Service Implementation Record is created:

trigger AutoCreateSI on Service_Agreement__c (after insert)
{
    if(!StaticClass.flag)
    {
        List<Service_Implementation__c> listSA = new List<Service_Implementation__c>();
        
        for(Service_Agreement__c s : trigger.new)
        if(Trigger.isInsert)
            {
                if(s.Name != '' )
                {
                  listSA.add(new Service_Implementation__c(name = s.Name, Service_Agreements__c = s.id));
               }
            }
    
        if(listSA.size() > 0)
        {
            insert listSA;
        }
        StaticClass.flag = true ;
    }
    }

 I feel that this is perhaps the problem - as when Step 1 is triggered - i.e a Service Agreement is created - this is when I want the Case to also be created - however I gather that the record is read only as it is creating the the Service Implementation Record. This is what i have so far for this Case trigger:

trigger AutoCreateAccountsCaseSI on Service_Agreement__c (after insert)
{
    if(!StaticClass.flag)
    {
        List<Case> listC = new List<Case>();
        Id rtId = [select Id,name from RecordType where name='Accounts' and SObjectType='Case' limit 1].Id;
        
        for(Service_Agreement__c s : trigger.new)
        {
            if(Trigger.isUpdate)
            {
                if(s.Has_Account_Manager__c = TRUE)
                {
                  listC.add(new Case(
                  RecordTypeId = rtId,
                  OwnerId='00520000001S0lx',
                  Requested_By1__c=s.OwnerId,
                  AccountId=s.Related_Account__c,
                  Service_Agreement__c=s.Id,
                  Origin='Salesforce Process',
                  Type='New Account / Service Agreement',
                  Subject='Account Financial Approval',
                  Description='Please confirm reciept of required financial information and approval for service implementation'
                  ));
                }
            }
            if(Trigger.isInsert)
            {
                if(s.Has_Account_Manager__c = TRUE)
                {
                  listC.add(new Case(
                  RecordTypeId = rtId,
                  OwnerId='00520000001S0lx',
                  Requested_By1__c=s.OwnerId,
                  AccountId=s.Related_Account__c,
                  Service_Agreement__c=s.Id,
                  Origin='Salesforce Process',
                  Type='New Account / Service Agreement',
                  Subject='Account Financial Approval',
                  Description='Please confirm reciept of required financial information and approval for service implementation'
                  ));
                }
            }
    
        if(listC.size() < 1)
        {
            insert listC;
        }
        StaticClass.flag = true ;
    }
}
} 

So, i guess my question is - how do you get two triggers to fire after the service agreement is created?

Again, thanks in advance for your help.
