You can change documents that have already been posted. To do this, however, you must satisfy certain conditions imposed by the system. This is necessary to prevent any changes to documents that could result in the undesired manipulation of data, which would then make reconciliation impossible.

You can also define your own conditions in the form of company-specific rules for changing documents. We recommend that you use the standard rules.


You can change documents or change line items in an account. If you want to change the line items for an account, the account needs to be managed using line item display. The change rules apply to changing documents and also to changing line items.


The system prevents the data in certain fields of a posted document from being changed. This includes fields such as: Posting Amount, Account, Posting Key, Fiscal Year, and Tax Amount. Because they have updated certain account balances during posting, these fields cannot be changed.

The system prevents other fields from being changed in certain transactions. With the net procedure, for example, you cannot change the cash discount amount when you post the payment.

Whether or not you can change data in those fields which are modifiable still depends on the following factors:

        The document change rules defined by your system administrator

        Which other SAP applications, such as CO (Controlling) or MM (Materials Management), are installed

        How these other applications have been customized.

The system prevents some fields from being changed if you use certain applications. For example, you can no longer change the account assignment to a cost center if you use Cost Center Accounting.

All document changes are logged. This also applies to changes to sample and recurring entry original documents.


With sample and recurring entry documents, you can change additional account assignments at any time. The restrictions do not apply to these special documents.

You can display the changes to a document in the document overview.
