Product group creation using java api doesn't work

[Sandip Mukherjee]

Hi Adwords Team,

I am trying to create Product group inside an adgroup using Java Api ProductPartitionTree.

In below sample, I try to create partition based on brand value.

AdWordsServicesInterface adWordsServices = AdWordsServices.getInstance();

            AdWordsSession adWordsSession = adwordsClientUtil.buildAdWordsSession("accountId");

            adWordsSession.setPartialFailure(false);

            ProductPartitionTree productPartitionTree =

                    ProductPartitionTree.createAdGroupTree(adWordsServices, adWordsSession, adGroupId);

            ProductPartitionNode rootNode = productPartitionTree.getRoot();

            rootNode = rootNode.asSubdivision();

            rootNode.

                    addChild(ProductDimensions.createBrand("brand_value"))

                    .asBiddableUnit();

            rootNode.addChild(ProductDimensions.createBrand(null))

                    .asExcludedUnit();

            List<AdGroupCriterionOperation> mutateOperations = productPartitionTree.getMutateOperations();

            AdGroupCriterionServiceInterface adGroupCriterionService

                    = adwordsClientUtil.getAdGroupCriterionService("accountId");

            AdGroupCriterionReturnValue adGroupCriterionResult =

                    adGroupCriterionService.mutate(

                            mutateOperations.toArray(new AdGroupCriterionOperation[0]));

But I get Below error for all mutate operation and the product group creation fails.

CAMPAIGN_TYPE_NOT_COMPATIBLE_WITH_PARTIAL_FAILURE

Can anyone from API team help on this please?

Thanks
