What does it do? A constructor expression with the component operator CORRESPONDING creates a result of a data type specified using dtype.
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 to form a tabular result.
The RAP-specific variants are used for creating structures or internal tables with type mapping in ABAP in the context of RAP. RAP requires BDEF derived types for the communication of RAP BO providers and RAP BO consumers. When including non-BDEF-derived types (ntype), the variants are responsible for matching them to the input ( in_d_type) and output BDEF derived types. The following can be specified for dtype:
