3392706 - Business partner missing in Journal Entry Voucher screen

Business Partner missing in Journal Entry Voucher screen.

SAP Business ByDesign

1. Go to Customer Invoicing Work Center -> Sales Transactions View.
2. In the dropdown, select "All transactions" and search for Transaction ABC.
3. Click on the number ID and go to View All -> Document Flow tab.
4. Go to the Journal Entry on the Sales Transactions.
   In Sales Transaction ABC, you will see that the business partner is shown on the screen, but in Sales Transaction ID XYZ, there's no business partner displayed.

(ABC/XYZ refers to the ID of the Sales Transactions)

In a POS (Point-of-Sales) Transaction, if Supplier is not available or is not affiliated, no partner company should be provided and will not be populated in Journal Entry. Also, if the debtor (customer) is not available or not affiliated, no Partner Company should be provided and will not be populated in Journal entry.
Also, In order to derive partner companies for postings to the Sales Ledger, ByDesign uses either the customer maintained in the Customer Project or the customer from the Sales Order. If the Business Partner maintained in both of those documents is not classified as a Partner Company, no Partner Company ID will be derived for the relevant line of the Journal Entry. 

This is a standard system behavior.
