ab SAP-Release 755: Hilfsklasse lcl_salv_helper mit Nutzung des Interfaces if_salv_table_display_adapter
* ab SAP-Release 755 (funktioniert ab SAP-Release 758 nicht mehr)
* SALV-Table: Hilfsklasse zur Ermittlung der Referenz auf ALV-Table (cl_gui_alv_grid) einer SALV-Table (cl_salv_table)
* ab SAP-Release 755 hat die Klasse CL_SALV_FULLSCREEN_ADAPTER keine Funktion get_grid( ) mehr
* somit muss das Coding ab SAP-Release 755 geändert werden
