Pending Fulfillment Sales Orders do not show in the Open Sales Orders Report

Please consider the following steps:

 

1. Check if Invoice in Advance of Fulfillment preference is enabled under Setup > Accounting > Accounting Preferences > Order Management tab > Invoicing section.

 

2. If Invoice in Advance of Fulfillment is enabled, check the Related Records tab of the sales orders in question to confirm if invoices have been created for them. 

 

3. If the sales orders have been invoiced for the full amount, then the report result is correct since the Open Sales Orders report lists open customer orders that have not yet been billed.
