To click the Transfer button without choosing a customer

Scenario: 

In the Sales module, if a user doesn't choose a customer, they won't be able to use the "Transfer" and "Partial Transfer" functions 

After select customer, the transfer function will be available.

Is there a setting which allow to use the transfer button without select the customer first?  

Solution 

Maintenance > System Options > Sales > Compulsory select customer to transfer document (Advisable to enable to have a better performance)

By default, this option is ticked. Thus, you need to select the customer first then only able to select “Transfer Button”

To click the Transfer button without choosing a customer, you can uncheck this setting.

Note: If you have a lot of transactions to transfer, the system might slow down.
