Final answer:
Before posting a parked document, typically editable fields include the Document date, Posting key, and Document type. The Company code is generally not editable once the document is initially parked. The flexibility in editing depends on system configuration and user permissions.
Step-by-step explanation:
Before posting a parked document in financial or accounting systems such as SAP, you can edit various fields. The fields that you are typically able to edit include:
Document date the date on which the document was created or entered into the system.
Document type - Classifies accounting documents and determines the account types that can be posted to (e.g., invoice, credit memo, payment, etc.).
However, the Company code is generally not editable as it defines the company or subsidiary within a corporation and is usually set when the document is initially parked. It's important to note that the ability to edit these fields may vary depending on the system's configuration and the permissions of the user.
