Salesforce 認定 Platform 基礎資格の受験準備 Salesforce オブジェクトをカスタマイズする レコードページをカスタマイズする で[Customer Account Page (カスタマー取引先ページ)] が [Customer Account (カスタマー取引先)] レコードタイプに対して有効化しても、有効化していない判定になってしまう。どのように対応したらよいか。

Hello @Under Dog

This error means the Customer Account Page isn't assigned to the Customer Account record type. To fix it: 

1. Go to Setup → type Lightning App Builder in Quick Find → click Lightning App Builder. 

2. Click Edit next to Customer Account Page. 

3. Click Activation (top right) → open the App, Record Type, and Profile tab → click Assign to Apps, Record Types, and Profiles. 

4. Select the app the challenge asks for (e.g. Sales) → Next → choose Desktop (or as instructed) → Next. 

5. Select the Customer Account record type → Next. 

6. Select the profiles the challenge asks for (e.g. System Administrator) → Next → Save. 

Also check that the Customer Account record type exists on Account, is Active, and is available to your profile (Setup → Object Manager → Account → Record Types). Then check the challenge again.
