Let me point out some information why the Transactions by Account report only shows some of the class assigned to some of the transactions, Risa K.

Generally, this depends on how the Class is assigned and what type of report you've pulled up. Every transaction (with the exception of journal entries) is separated into a header and a detail portion. When classes are assigned, they get attached to the detailed portion of transactions. They do not get associated with the header accounts.

Also, if the account being reported is a header type of account, the class data does not get saved with the header. Bank accounts, loan accounts, and all header types of accounts cannot be linked to a class on the reports.

You'll want to run the Customer Balance Detail Report and filter it by Class. To do this, you can follow the steps below:

1. Click Reports at the top menu bar. 
2. On the drop-down list, click Customers & Receivables and choose Customer Balance Detail. 
3. Click Customize Report.
4. From Filters, search Class.  
5. Click the drop-down arrow from Class and choose the specific company you want to show in the report. 

    

6. Press OK.

The type of transaction information pulled into a report depends on the type of report. For example:

• Reports that are reporting income and expense account information, pull information from the detail of transactions.
• Reports that are reporting asset, liability, and equity account information, pull information from the header portions of transactions.
