Updating Customer or Supplier Records
Use Blocked Customer Maintenance (2.23.4) and Blocked Supplier Maintenance (2.23.7) to assign a blocked code to customers and suppliers. Each customer or supplier can be assigned only one blocked code.
Once a customer or supplier is assigned a blocked code, the transactions identified by the code cannot be created for that customer or supplier.
Blocked Customer Maintenance (2.23.4) illustrates Blocked Customer Maintenance. Blocked Supplier Maintenance is exactly the same.

Blocked Customer Maintenance (2.23.4)
You can remove this restriction by deleting the relevant record from Blocked Customer Maintenance (2.23.4) or Blocked Supplier Maintenance (2.23.7).
Blocked Customer Report (2.23.5) and Blocked Supplier Report (2.23.8; 2.23.32 for enhanced .NET UI version) list blocked customers and suppliers and provide details of their blocked transactions. You can display information for a single blocked customer or supplier, or for a range of customers or suppliers.
