why i can not change the fillter in my custom reports

Hi there, Waleed.

I can show you the steps on how to change the filter in your custom reports.

Here's how:

1. Sign in to your QuickBooks Online account.
2. On the left side of your screen, click Reports.
3. Select the custom report you want to change or create a new one.
4. On the right side of your screen, choose Filters.
   Note: Some reports don’t include filter options, but you can use the ⚙ icon to adjust the settings.
5. Adjust the filters to suit your needs, like choosing specific accounts, customers, vendors, or types of transactions.
6. Then, click Save As.
