Items Errors while data entry

here is the attachment 

Have you tried these troubleshoots?

1. Run the Verify/Rebuild Data utility

2. Create a backup file, restore it with a new name and open the file.

Let me help you perform some troubleshooting steps and get those existing items to appear on the invoice, Ahmadi.

There are times when your company file is damaged, which leads to being unable to perform some tasks. To fix this, you can run the Verify and Rebuild Data utilities.

Before you get started, make sure to backup your company file. Then, follow these steps to scan your company file for errors or data damage.

To Verify Data:

1. Choose Window then Close All.
2. Choose File then Utilities. Select Verify Data.
3. If you see:
   • "QuickBooks detected no problems with your data," no further action is needed.
   • A specific error message, there may already be an article for it. Try searching for it in our QuickBooks Desktop support site for specific instructions.
   • "Your data has lost integrity," indicates there is data damage in the file.  Continue to the steps below to Rebuild Data to correct the problem. Go to File, then select Utilities.
4. Select Verify Data, then click OK to close all windows.
5. If you see “Your data has failed the integrity check” you need to rebuild your file. If there are no problems with your data, you’re done.

To Rebuild Data:

1. Choose File, Utilities then Rebuild Data.
2. You will receive a warning message to backup your company file, press OK.
3. Choose where you want to save your backup, then click OK at the bottom of the QuickBooks Desktop Backup window.
   • If a message asks if you want to replace another backup file, select NO. Enter a new name in the File name field and click Save.
   • If the backup fails, select Cancel at the Rebuild prompt and contact Payroll Support for additional assistance.
4. The Rebuild Data utility starts as soon as the backup is finished.
5. Click OK when you get the message "Rebuild has completed".

After running those utility tools, re-sorting the item list can also fix data damage on your company file. Please keep in mind that you'll need to close and re-open your company file after re-sorting a specific list.

Once done, you can ask the client to create again the invoice. If you get the same result, I recommend contacting our QuickBooks Live Team. They can have a screen-sharing session with you to take a closer look at your issue.

Let me know if you have any follow-up questions about the item not showing on the list. I'll be here if you need further assistance. Take care always.

Thank you for answering to my question, I try 1st opinion and I will try end option you recommended.
