Which of the following statements about the cancellation of delivery documents are correct?

The statement regarding the cancellation document correctly highlights the automatic execution of the corresponding posting in Financial Accounting upon saving the cancellation document. This admission reflects the integrated nature of SAP systems, where actions taken in one module often trigger automatic updates in connected modules. For instance, when a billing document is canceled, the relevant financial impacts must also be reversed to maintain accurate accounting records. By automating these postings, SAP ensures data consistency and streamlines the accounting process, reducing the likelihood of errors that could arise from manual intervention.

In the context of the other statements, while they may contain accurate assertions about various aspects of delivery document cancellations, they do not capture the direct impact and integration level that is emphasized in the correct statement. For example, the inability to reverse a billing document created in a collective billing run addresses a specific limitation without influencing financial postings. Similarly, resetting the billing status of related documents and the ability to change pricing conditions during the cancellation process, while relevant, do not directly connect to the execution of financial postings—making those statements less pertinent in showcasing the process's holistic nature.
