Creates a work area that is compatible with a database table in the INTO clause and reads the first rows (rows) of the database table into this work area using a SELECT loop. Since the data reference row is typed generically, access to the work area can only take place using the field symbol <fs>.

The method CHECK_TABLE_NAME_STR of the class CL_ABAP_DYN_PRG checks whether the database table specified exists and can be used.
