What is the reason for this issue?
It takes at least 30 days to be able to use tags to filter views in Cost Explorer.
The company has not activated the user-defined tags for cost allocation.
The company has not created an AWS Cost and Usage Report.
The company has not created a usage budget in AWS Budgets.
Explanations:
It does not take at least 30 days to use tags for filtering in Cost Explorer. The issue is not related to a fixed waiting period of 30 days.
Tags must be specifically activated for cost allocation in the AWS Billing console. Without this activation, the tags will not be available for filtering in Cost Explorer.
A Cost and Usage Report is not required for using tags in Cost Explorer. Tags can be used for cost allocation without a report being created.
A usage budget in AWS Budgets is unrelated to the ability to filter by tags in Cost Explorer. Budgets are used for cost management and alerts, not for filtering.
I scheme that the answer is:
The company has not activated the user-defined tags for cost allocation.
I structure that the answer is:
The company has not activated the user-defined tags for cost allocation.
