F-48 — Post Vendor Down Payment
F-48 is used to post an outgoing vendor down payment using the configured special G/L transaction. It is most useful when an approved supplier advance is paid manually or as part of an integrated procurement down-payment process. Start with the exact organizational keys, business document and date, then reconcile the resulting SAP document or status before changing master data or configuration.

Purpose
post an outgoing vendor down payment using the configured special G/L transaction. Treat F-48 as one step in an end-to-end process. Values shown or posted here are usually driven by master data, organization, dates and preceding documents, so an accurate diagnosis starts by preserving those inputs rather than changing the symptom screen first.
When it is used
F-48 is typically used when an approved supplier advance is paid manually or as part of an integrated procurement down-payment process. It is also valuable in project and regression testing because it provides a repeatable business state. In production, use the narrowest document or organizational selection that answers the question and capture the before-state before any posting, clearing or configuration change.
How to use it in practice
- Confirm payment approval and bank/payment details.
- Enter vendor, amount, dates and special G/L indicator.
- Reference the purchase order or request where the process requires it.
- Simulate to verify bank and vendor special G/L posting.
- Post and verify the vendor open item.
Key data objects
These are the fields and business objects that most often explain the result in F-48. Record them in support evidence so the next person can reproduce the same outcome.
- vendor/company code — verify the exact value, validity/date context and relationship to the source document.
- bank account — verify the exact value, validity/date context and relationship to the source document.
- special G/L indicator — verify the exact value, validity/date context and relationship to the source document.
- amount — verify the exact value, validity/date context and relationship to the source document.
- PO/down-payment request reference — verify the exact value, validity/date context and relationship to the source document.
How to prove it in the data
Use document flow and chronology. Start from the source business event, inspect the F-48 document or master data, then follow the resulting accounting, purchasing or asset document and reconcile amount, quantity, account assignment and status. A correct proof uses the same company code or plant, business date, document keys and currency/unit context at every step.
ECC vs S/4HANA
SAP documentation explicitly references F-48 for vendor down payments in S/4HANA payment integration. Where S/4HANA offers a Fiori successor or a changed data model, the classic transaction can still be valuable for support, but the strategic process and clean-core guidance should govern new implementations.
Common pitfalls and how to diagnose them
- Paying the wrong vendor or without approved advance terms. Reconcile the exact business document and date before applying a workaround.
- Using a normal vendor posting instead of special G/L. Reconcile the exact business document and date before applying a workaround.
- Ignoring withholding/local tax handling where applicable. Reconcile the exact business document and date before applying a workaround.
Whose problem this is
Primary ownership is the Finance/Controlling team, with adjacent teams involved when the evidence crosses into Asset Accounting, Project System, tax, Basis, Security or integration. Escalate with document numbers, organization, dates, expected result, actual result and checks already completed.
