Error
An item has a blank sales account number (Expenses)
Applies to: ConnectWise Manage
How can this happen?
This happens when you have missing GL Account Mappings for either Internal or External Expenses.
Solution
You need to ensure you have the GL Account Mappings for both Expense Types: Internal and External Expenses. For the detailed instructions, refer to this KB Article: GL Mapping of Expense Types
Note
If the Expenses were created before your Mappings were created, then you can refresh the GL Entries via the Accounting Interface.
