This field specifies the accounting date to assign to the generated documents, considering following exceptions:
- the documents generated during the first posting stage of a payment are always generated at payment date.
- The documents generated during the bank posting for a payment associated with a transaction with open item date management are always generated at payment due date.
- if there is no date assigned, the posting date is taken from the "Accounting date" formula of the automatic journal associated with the transaction for the current posting stage.
