Which of the following is NOT an aggregation type defined in the BDC component?

The aggregation type that is NOT defined in the BDC component is the median. In the context of data aggregation in SAP, the BDC (Batch Data Communication) component supports specific methods such as sum, maximum, and average. These methods are commonly used to calculate summary statistics from a dataset, allowing users to analyze data effectively.

The sum provides the total of all values, the maximum identifies the highest value, and the average determines the central tendency of the values. However, the median, which is the middle value in a data set when arranged in order, is not included as a standard aggregation type in the BDC component. The absence of the median indicates that the BDC is designed primarily to support simpler aggregation methods that are more frequently used in transactional processing and reporting tasks within SAP systems.
