Changing Documents

Users can change documents that they have already posted. However, based on different rules, users may only be able to change certain fields.
The following fields can be changed in a document:
- Document header
Reference number and document header text
- Line items
For example: Assignment field, Text field, and Payment Terms
Note
The amount, posting key, account, or any other fields that affect the reconciliation of a posting cannot be changed.
As users make changes to documents, SAP S/4HANA logs the following information:
- The field that was changed
- The new and old values
- The user who made the change
- The time and date of the change
Document Change Rules

You can use the following criteria to differentiate between document change rules:
- Account type
The account type allows users to define rules for customer, vendor, and general ledger accounts.
- Transaction class
The transaction class is only used for the special general ledger transactions, such as bills of exchange and down payments.
- Company code
If the company code is left blank, the change rule applies to every company code in the client.
You can change a field under the following conditions:
- The posting period is still open.
- The line item is not yet cleared.
- The line item is either a debit in a customer account or a credit in a vendor account.
- The document is not a credit memo for an invoice.
- The document is not a credit memo from a down payment.
You can use report RFBABL00 to display the document changes for all documents.
This report provides the following selection options for documents that have changed:
- Company code
- Document numbers
- Fiscal year
- Change date
- User name of the person making the change
