Symptom
The "Purchasing Document" and "Profit Center" information are not displayed when using "Manage Supplier Line Items" app.
Environment
SAP S/4HANA Cloud Public Edition
Cause
For a supplier line item, which is displayed in "Manage Supplier Line Items" app, can represent an invoice for multiple purchase orders (one [invoice line item] to many [purchase orders] relationship).
So this cannot be displayed in one line item list report. The app can only display fields with one-one relation.
Therefore, for a specific supplier line item it may have two or more purchase orders and the same for other fields like cost centers, profit centers and etc.
Resolution
For "Purchasing Document" field, click the "Journal Entry" number in the "Manage Supplier Line Items" app and select "Display Process Flow - Account Payable".
For "Profit Center" field, there is a work-around by using the app "Display Line Items in General Ledger".
