The REBZG field in SAP is used to reference the original document for a subsequent transaction, such as a clearing document or a payment. The field can contain several different values, each with its own meaning. The following are the possible values for the REBZG field in SAP:
Document number: When a subsequent transaction, such as a clearing document, is created to reference a specific original document, the REBZG field will contain the document number of the original document. This value indicates that the subsequent transaction is related to a specific document and is used for audit trail purposes.
'V': When a subsequent transaction is not referencing a specific original document, such as in the case of a down payment or a write-off, the REBZG field will contain the value 'V'. This value indicates that the subsequent transaction is not related to a specific document and is used to identify transactions that do not have a specific reference.
'A': When an accounting document is reversed, the system will create a reversal document with the REBZG field containing the value 'A'. This value indicates that the reversal document is related to the original document and is used for audit trail purposes.
'C': When a payment is made against an outstanding invoice, the system will create a payment document with the REBZG field containing the value 'C'. This value indicates that the payment document is related to the original invoice and is used for audit trail purposes.
Blank: If the REBZG field is blank, it indicates that the subsequent transaction is not referencing any specific original document.
In summary, the REBZG field in SAP can contain several different values, each with its own meaning. These values are used to identify the relationship between subsequent transactions and the original documents they reference, and are important for audit trail purposes.
