Final answer:
SAP personnel typically do not need to report a surname change if they are not changing their surname upon marriage, but reporting marital status change may still be a best practice for accurate records.
Step-by-step explanation:
Whether or not SAP personnel who marry and choose to keep their surnames need to report the change could depend on the company's internal policies or the legal requirements of the jurisdiction in which they operate. Generally, there may not be a need to report a surname change if the surname is not being altered. However, it is best practice to report any significant personal changes to the human resources department of a company, including marital status, even if the surname remains the same. This helps ensure that personal records are up to date, which can be important for tax purposes, benefits, emergency contacts, and employment documentation.
