Review all error messages below to correct your data.
Apex trigger SyncField caused an unexpected exception, contact your administrator: SyncField: data changed by trigger for field Owner ID: id value of incorrect type: a0b0k000000sivZAAQ
  
trigger SyncField on Object2__c (before insert, before update) {
  for(Object2__c ao:Trigger.new)                                    
    if(Trigger.isInsert)                                             
      ao.OwnerId = ao.object1__c;                                   
    else                                                            
      if(ao.OwnerId != Trigger.oldMap.get(ao.id).OwnerId)         
        ao.object1__c= ao.OwnerId;                                 
      else

Hi,

I think you are requirement is a bit not clear because if you want to the change the owner of the parent based on child's owner (WRONG).
Explanation : The owner field of the parent gets updated for every child creation, Which directly states that the owner field value depends on the newest child owner's value.

Is your requirement is this for sure. Then try the following code.
Trigger SyncField on Object2__c (after insert, after update) {
   List<Object1__c> oaList = new List<Object1__c>();
   if(Trigger.isAfter && (Trigger.isInsert || Trigger.isUpdate)) {
       for(Object2__c o : Trigger.new) {
          Object1__c oa = new Object1__c(Id = o.ParentFieldApiName);
           oa.OnwerId = o.OwnerId;
           oaList.add(oa);
       }
          update oaList;
  }
}

You saying that you wanted to update child's record owner based on parents record owner field ?
 Then the code would be :
Trigger SyncField on Object2__c (before  insert, before update) {
   Set<Id> parentId = new Set<Id>();
   List<Object1__c> oList = new List<Object1__c>();
   if(Trigger.isBefore && (Trigger.isInsert || Trigger.isUpdate)) {
       for(Object2__c o : Trigger.new) {
           parentId.add(o.ParentFieldApiName);
        }
       Object1__c parentVal = [select ownerId from Object1__c where id = : parentId];
       for(Object2__c o : Trigger.new) {
          o.ownerId = parentVal.ownerId;
          oList.add(o);
       }
       update oList;
       }
}

After using I am getting error Error: Compile Error: No such column 'ownerId' on entity 'Purchase_Order__c'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names. at line 8 column 38 *Trigger SyncField on Invoice_Dispatch_details__c (before insert, before update) { Set parentId = new Set(); List oList = new List(); if(Trigger.isBefore && (Trigger.isInsert || Trigger.isUpdate)) { for(Invoice_Dispatch_details__c o : Trigger.new) { parentId.add(o.ParentFieldApiName); } Purchase_Order__c parentVal = [select id,ownerId from Purchase_Order__c where id = : parentId]; for(Invoice_Dispatch_details__c o : Trigger.new) { o.ownerId = parentVal.ownerId; oList.add(o); } update oList; }} *

Hi,

Please use owner.Id, instead of ownerId. It will work.
