Reverse Document
Application component: Contract Accounts Receivable and Payable
App type: SAP GUI
Description:  A document posting or clearing of open items, and all postings that were created automatically this way may, depending on the circumstance, have to be reversed. Depending on the situation, you choose one of the following functions: Returns Reset Clearing Reversal of Documents (transaction FP08)  
Key features:  Reversing a Document Two reports are available: In the classic method, open business partner items are cleared by the reversal and clearing is cancelled by the reversal. The second method is restricted to the creation of offsetting items. Use this method particularly if the document to be reversed has already been archived and neither clearing nor clearing reset is therefore possible. Reversing a document has the following effect: Depending on the reversal method selected, the system clears all business partner items of the document or creates offsetting items with opposite +/- signs. In the reversal document, for every general ledger item, the system creates a corresponding item with the opposite +/- sign.  Reversing Payment Documents Reversing a payment document has the following effect: Depending on the selected reversal method, the system either resets the clearing data of the items originally paid or creates offsetting items for the clearing items within the reversal document. If clearing is reset, in the payment document the system creates one or more business partner items as replacement for clearing. These replacement items are cleared by the reversal document. The system logs the transaction in the clearing history, provided clearing is to be reset.  Before reversing a document, you can use the Cleared Items function to check whether you have entered the correct document number.If you reverse a payment document that was posted directly without clarification by using a dialog box when posting the reversal, you can decide whether you want to reverse the payment document or transfer to the clarification account. If the clarification case is created for a payment lot that has already been closed, the status changes again to Postprocessing Necessary. Reversing a Clarification Document or Partial Clarification Document When you reverse a clarification or partial clarification document for an incoming payment, a new clarification case for incoming payments is created automatically or the amount to be clarified is adjusted in an existing clarification case. Special Features for Documents with Cleared Items If you manually reverse a document that contains cleared items, an overview screen with all clearings appears. You cannot execute the reversal unless you reset these clearings. The overview screen displays the date and origin of the clearing documents and whether additional documents were cleared by this clearing. You can display the clearing documents or initiate the clearing reset via function keys. You can carry out the clearing individually online or carry out all clearing in the background. If you carry out clearing online, you can also partially reset clearing and thereby retain the distribution of the clearing amounts to the accounts. Special features for documents with repetition specifications If a document contains repetition items, you can reverse a specific repetition specification by specifying the posting date of the repetition specification to be reversed in the Repetition Date field. Alternatively, you can reverse all repetitions that are still open. Special Features for Reversing More Than One Document You can reverse all documents with the same reference document number or classification key (if this enhancement is active) together as a group. You can use a simulation to check whether documents that were selected on the basis of a reference number or classification key can be reversed. The system issues a list with the selected documents. In this list, error messages may indicate that individual documents cannot be reversed. Special Features for Reversing Archived Documents Archived documents usually have business partner items that are cleared (for example, paid invoices), or have cleared business partner items themselves (for example, payments). The only exception is documents that exclusively contain general ledger items. Since no data may be changed for an archived document, it is not possible to reset clearing as part of a reversal. Therefore, for archived documents, you have to select another form of reversal. When you reverse archived documents, the system therefore creates new business partner items in the reversal document. Example Reversal of an Archived InvoiceIn the reversal document, a business partner item with the opposite plus/minus sign is created for each business partner item of the invoice document. In this case, the reversal document is a credit memo posting for the full invoice amount.Reversal of an Archived PaymentIn the reversal document, business partner items with the same amount are created for paid receivable items. This is identical to the procedure for returns if new receivables are created derived from the payment. If a document that still contains open business partner items is reversed such that the system creates offsetting postings, account maintenance takes place automatically after the reversal; the open items of the document to be reversed are cleared against the open items of the reversal document. Caution When you reverse an archived document, you cannot trigger a workflow for confirming the reversal. Event 5502, which can be used to trigger such a workflow, is not processed in this case.Further restrictions are described in the documentation for the Reversal Method field on the initial screen of the reversal transaction.
