Hi, 

I have an established piece of code. What it is doing is writing, on save, from one record (week__c) in an object, and creating/updating a series of records in another one (PCM_Time_Record__c).

The only bugbear is that it is writing the other records as whoever is triggering the Apex. I need it to assign the written records as the owner of the source.

The code looks like this:

 List<PCM_Time_Record__c> insertBlocks = new List<PCM_Time_Record__c>
     {new PCM_Time_Record__c(Time_Block_Name__c='Monday AM1', Type__c=week.Monday_AM1__c,      Date__c=week.Week_Commencing__c, Weekly_Time__c = week.Id,RecordTypeId=recordTypeId, Duration_hours__c=hours, Proportion_Of_Day__c=0.25),

As you can see, it is doing a simple create.

I assumed it was as simple as adding another clause to the bracket that said OwnerID = week__c.OwnerID, but that is throwing up an "Expect ID error".

Here is the full trigger in case anyone needs it:

trigger createTimeBlocks on Week__c (after insert, after update) {
   
    //hours in the day, split into quarters
    decimal hours = 7.5/4;
    String recordTypeId = [Select Id from RecordType where Name = 'Time Block' and SobjectType = 'PCM_Time_Record__c' limit 1].id;
    PCM_Time_Record__c timeBlock;
        
    for (Week__c week : Trigger.new)
    {
     //For each week record being saved
     if(Trigger.isUpdate)
     {
        //If the Week record has been saved previously, then check for existing timeBlocks. These should also exist.
        List<PCM_Time_Record__c> timeBlocks = [select id from PCM_Time_Record__c where Weekly_Time__c = :week.Id];
        if(!timeBlocks.isEmpty())
        {
            delete timeBlocks;
        }   

     }
     //Create timeblocks.
     List<PCM_Time_Record__c> insertBlocks = new List<PCM_Time_Record__c>
        {new PCM_Time_Record__c(Time_Block_Name__c='Monday AM1', Type__c=week.Monday_AM1__c, Date__c=week.Week_Commencing__c, Weekly_Time__c = week.Id,RecordTypeId=recordTypeId, Duration_hours__c=hours, Proportion_Of_Day__c=0.25),
