Hi Duy,
By GCP do you mean the
Google Cloud Project? If yes, then for example if the user / email address used to generate the GCP and the credentials, has
access to the MCC where all your client accounts belong to, then you should be able to access all of them.
That said, if your user / email address only has access to a select number of client accounts, then you may only be able to generate reports for those accounts where the said user was given access to, and not all the accounts under the MCC's hierarchy.
As for generating reports, if you are using the
search (see this
guide) requests / methods, then these are subject to your
access level's daily operation limit.
Best regards,
