ABAP_DESCRIPTION
The columns of an internal table can be assigned to columns with different names in a different table in three different ways:

Constructor expression with component operator CORRESPONDING and mapping rule

Explicit assignment of the individual components behind a FOR expression of a table comprehension.

FOR expression with evaluation of a constructor expression with component operator for each line.
Each method provides the same results. The component operator is quicker than the table comprehension when there are more than approximately 10 iterations. Using the component operator for each line is always the slowest solution.
