I've got the steps for fixing data damage on your QuickBooks Desktop (QBDT) company file, FelixM.

For possible data issues, you can follow the solutions below to fix it:

First Solution: Repair your company file using the Rebuild Data tool

1. Go to the File menu, then Utilities. Select Rebuild Data.
2. On the QuickBooks Information window, select OK. Follow the onscreen steps to save a backup.
3. Let the tool repair your file. It may take some time. QuickBooks may seem stuck, but as long as you can move your mouse, then it's working.
4. When the tool finishes, select OK.
5. Go to the File menu, then Utilities. Select Verify Data.
6. Let the tool check your file for data issues.

If QuickBooks doesn't find any problems, hit OK. You can keep using your company file.

If QuickBooks finds an issue with your company file, select Rebuild Now.

Second Solution: Use the QuickBooks File Doctor to fix your company file if you still have data issues.

Third Solution: Manually repair your company file by rebuilding your data

You can find the errors you can fix from the Verify Results window. Make sure to back up your company file.

To manually fix data errors:

1. Go to the File menu, then Utilities. Select Verify Data.
2. Let the tool check your file for data issues.
3. From the Verify Results screen, click Expand All to see the errors.
