Effect

A constructor expression with the component operator CORRESPONDING creates a result of a data type specified using type.

In the basic component, the components of a structured or tabular results are constructed from the components of a structured or tabular parameter struc or itab.

In the variant with lookup table, the components of an internal table itab and a lookup table lookup_tab are combined with a tabular result.

The following can be specified for type:

A structured type or a table type.

The # character as a symbol for the operand type. Can be specified only if the data type required in an operand position is unique and fully identifiable. The operand type must be a structure type or a table type. When a constructor expression is assigned to a field symbol or to a formal parameter with a generic table type, the operand type can only be determined at runtime.

The operator creates structures or internal tables with the specified data type. The components or columns of the result are filled using assignments of components of the parameters specified in the parentheses. The assignments are made using matching names or mapping relationships in a mapping rule.
