Modifying existing Product Partition trees

[CDG]

Hello there

I am using the python example to create Product Partition trees

Now

I want to update the tree, but I always get the error.

--

'trigger': None,

'errorString': 'AdGroupCriterionError.PRODUCT_PARTITION_ALREADY_EXISTS',

'ApiError.Type': 'AdGroupCriterionError',

'reason': 'PRODUCT_PARTITION_ALREADY_EXISTS'

---

help me to solve the problem, thanks.

Hi,

Based on the error, your request for creating a subdivision is failing because there is already an existing product partition. I would recommend that you first use the AdGroupCriterion.GetAdGroupCriterion method to see whether the partition already exists before trying to create one.

You may send to me your JSON logs, using the Reply privately to author option, should the issue persist.

Thanks and regards,

Do you still need help with this?  Here is some example in code from one of my python scripts

adgroup_criterion_service = client.GetService(
    'AdGroupCriterionService', version='v201809')

selector = {
  'fields':['ParentCriterionId'],
    'predicates':[
        {
            'field':'AdGroupId',
            'operator': 'EQUALS',
            'values': adgroup_id
        }
    ]
}
page = adgroup_criterion_service.get(selector)

parent = page['entries'][0]['criterion']

helper = ProductPartitionHelper(adgroup_id)
#root = helper.CreateSubdivision()

for pla in PLAList:
    new_product = {
        'xsi_type' : 'ProductOfferId',
        'value' : ''
    }
    new_product['value'] = pla
    #helper.CreateUnit(self,parent=parent, new_product, 200000)
    helper.CreateUnit(parent=parent,value=new_product,bid_amount=20000)

other_products = {
    'xsi_type': 'ProductOfferId',
}

#helper.CreateUnit(
#    root, other_products)

# Make the mutate request
result = adgroup_criterion_service.mutate(helper.GetOperations())

---

You need to use the adgroup_criterion_service get on the parentcriterionID to get the tree, then mutate the tree.  

I iterate through my list of Ids to add "for pla in PLAList" -- note you cannot add more than 5000~ in a single mutate -- and there are limits to how large the tree can be - if you exceed something like 12-13k it will give an exception.
--

Hope this helps you out - it took me a while to understand how to manipulate these.  The example only works for creating the tree, so it errors if you try to do it where one already exists.

hi Kevin,

Thank you for your answer.

,

I am currently able to create tree content and add it to the Google advertising product group through examples and your responses.

I want to ask is, is there any way to modify the created tree?

Hi,

Could you confirm if you are indeed using the old AdWords API? If yes, you will need to specify the ProductPartition's Id in the your AdGroupCriterionService.mutate() SET request and include the fields you wish to modify. In the event that you wish to ADD or REMOVE a node to a subdivision, you will then need to specify the parentCriterionId.

You can - but due to the nature of how product trees exist, you have to ensure every mutate results in a valid resulting tree, else the call will fail.

You can use a similar method to 'remove' product groups.

Note - due to a size limit, you may not be able to perform too many changes at a time else the calls will fail.  When I remove product groups, I submit mutate requests with each pass - unlike with the creation, where I submit many in a single mutate.
==

You can do bid arguments with the same style- using "SET" as Peter stated.

Hi everyone,

Thank you Kevin for the additional information. For bulk updates on your ProductPartitions, you can use the BatchJobService and you can refer to this section for the considerations in order to successfully execute your requests.
