Which of the following prerequisites must be met for the system to check the shelf life of materials at goods receipt?

The correct answer is that all the prerequisites must be met for the system to effectively check the shelf life of materials during goods receipt.

For the shelf life expiration date check to function properly, it is essential that the activation is done at multiple levels. First, the shelf life expiration date check must specifically be activated for the movement type in Customizing. This ensures that the system knows to perform the necessary checks related to shelf life for specific movements associated with inventory management.

Additionally, the purchase order item must contain relevant data about the remaining shelf life. This information is critical as it informs the system of the actual shelf-life status of the materials being received, allowing for accurate evaluations and decisions during the goods receipt process.

Furthermore, activating the shelf life expiration date check for the plant in Customizing ensures that the rules for shelf life checks are uniformly applied across all materials in the relevant plant environment. Each of these conditions plays a key role in enabling a comprehensive and automated way to manage shelf life effectively.

In summary, all these components work together to facilitate the accurate tracking of shelf life at goods receipt, thus making it necessary for all the prerequisites to be satisfied for the system to perform the check successfully.
