What access method allows you to read data from an internal table at a specified index?

The access method that allows you to read data from an internal table at a specified index is referred to as READ TABLE. This command is specifically designed for accessing rows in an internal table by providing the index of the desired entry.

When using READ TABLE, you can directly specify which row you want to retrieve based on its numeric index. This makes it a precise and efficient method for accessing data stored within an internal table when you know the position of the data you want to read. The ability to specify an index directly is critical for scenarios where the order of entries is important, and you wish to access elements quickly without needing to iterate over the entire table.

In contrast, LOOP AT is used for iterating over all entries in an internal table, which does not provide direct access to a specific index. SORT is employed to arrange the data in a specific order but does not facilitate reading data directly from an index. Lastly, COLLECT is utilized for aggregating data in a transparent table, but it does not serve the purpose of accessing specific entries at an index.

Thus, READ TABLE stands out as the correct choice due to its functionality tailored for direct access at a specified index within an internal table.
