Which command or action is necessary to track revenues in SAP S/4HANA?

To track revenues effectively in SAP S/4HANA, setting up an internal order is key. Internal orders are used for tracking costs and revenues associated with specific projects, activities, or events within an organization. They allow for detailed tracking and reporting, which can help in understanding the financial performance of different initiatives.

By utilizing internal orders, organizations can assign revenues directly to these orders when they occur, thus providing insights into profitability and financial management. This is essential for businesses that need to analyze the performance of various projects or cost centers thoroughly. Additionally, internal orders can be linked to budgets and can have planned versus actual comparisons, aiding in effective financial oversight.

While the other options, such as using a production order, monitoring operating expenses, or creating a depreciation run, are elements of financial and operational management, they do not specifically address the direct tracking of revenues. Production orders focus primarily on tracking production costs; monitoring operating expenses relates to overall expense management without specific revenue tracking; and creating a depreciation run is related to asset management, which does not involve revenue tracking directly. Thus, internal orders are the most relevant and effective option for tracking revenues within SAP S/4HANA.
