How do I use more than one USAGE_TYPE_GROUP value in GetUsageForecastRequest API?

[kakjzi]

When I try to use more than one USAGE_TYPE_GROUP in the GetUsageForecastRequest API, the following error occurs.

Error occurred: Unable to identify the usage unit. Provide USAGE_TYPE/USAGE_TYPE_GROUP filter selections that contain matching units (e.g. hours). (Service: AWSCostExplorer; Status Code: 400; Error Code: UnresolvableUsageUnitException; Request ID: 33248fb8-986e-4358-af0c-49adef64b2da; Proxy: null)

My code :

    public void foreCastTest(String billingAccount) throws IOException {

        AWSCostExplorer costExplorer = AWSCostExplorerClientBuilder.standard()
                                                                   .withCredentials(AWSCredentialsUtil.getCreds(billingAccount))
                                                                   .build();

        GetUsageForecastRequest request = new GetUsageForecastRequest()
                .withTimePeriod(new DateInterval().withStart("2023-05-03")
                                                  .withEnd("2023-09-01"))
                .withGranularity(Granularity.DAILY)
                .withMetric(Metric.USAGE_QUANTITY)
                .withFilter(new Expression()
                                    .withDimensions(new DimensionValues().withKey(Dimension.USAGE_TYPE_GROUP)
                                                                     .withValues("EC2: Running Hours", "S3: Storage - Standard")));

        try {
            GetUsageForecastResult result = costExplorer.getUsageForecast(request);
            System.out.println("Usage Forecast: " + result.getForecastResultsByTime());
        } catch (Exception e) {
            System.err.println("Error occurred: " + e.getMessage());
        }
    }

I'm using aws-java-sdk 1.11.807, and my code looks like this.
And It works fine when I specify only one USAGE_TYPE_GROUP.
If I'm missing something or doing something wrong, please help.

In addition, the official documentation for GetUsageForecast (https://docs.aws.amazon.com/aws-cost-management/latest/APIReference/API_GetUsageForecast.html) says that the Filter option is not required. However, when I test it on my local PC (version 1.11.807), the following error occurs.

Error occurred: Unable to identify the usage unit. Provide USAGE_TYPE/USAGE_TYPE_GROUP filter selections that contain matching units (e.g. hours). (Service: AWSCostExplorer; Status Code: 400; Error Code: UnresolvableUsageUnitException; Request ID: 33248fb8-986e-4358-af0c-49adef64b2da; Proxy: null)

Is this issue caused by the difference between the sdk version on my local PC and the official AWS documentation description?

Hello @kakjzi,

Thank you for submitting your question.

Can you try removing the spaces adjacent to the hyphen for the filter value "S3: Storage - Standard"?
.withValues("EC2: Running Hours", "S3: Storage-Standard")

The hyphenated spaces seems to be an issue when having multiple USAGE_TYPE_GROUP values.

I am checking with the Cost Explorer service team for their further investigation on this issue. Also, I have asked the team regarding the documentation that states Filter isn't a required parameter but then we encounter a similar exception when it isn't passed.

Regards,
Chaitanya

@bhoradc I did what you suggested and it works fine. Thanks.👍

And let me know if you get an answer to the "similar exception thrown when Filter is not a required parameter but is not passed" question

@bhoradc Hi,

I was wondering if anyone had an answer to my question about a similar exception being thrown if Filter is not a required parameter but is not passed?
