One account data is missed (Quick Start) system manager -- multi-accounts

Hello,

Warm Greetings !

Based on the above details, it seems you are trying to use "Quick Setup" feature of Systems Manager, where one of the account information is missing which is part of your Organization.

However, after reviewing the details around the account used to create this post, I can see that there is only 1 account in this Organization and no member accounts are present. Hence, based on this,

• either the accounts have been removed from your Organization which is the reason they are not shown
  OR
• else you have opened this post from a different Organization than the one being used in above use-case.

If the post is opened from an account which is part of different Organization, I will not be able to review your resources as we as AWS Support Engineers do not have access to Cross account resources as per the Security best practices.

So, in order to confirm if all the accounts are shown, I would request you to first login into your Management account of Organization (i.e. the account used to create the Organization) and confirm the accounts which are shown as part of this Organization in the Organization console.

This will confirm what accounts are part of your Organization and ideally all of them should be shown in the configuration page.
