No Shipping Methods available on Sales Transactions even if they were created under Lists > Accounting > Shipping Items

There are instances where the Customer (Lists > Relationship > Customers) does not have the same subsidiary as the Shipping Items (Lists > Accounting > Shipping Items).

 

Simply make changes to the subsidiary on Shipping Items (Lists > Accounting > Shipping Items). As soon as the customer selected has the same subsidiary as the shipping item, it will show up on the shipping method field under sales transaction.
