ABAP_DESCRIPTION The inline declarations of the first two SELECT statements create the same internal tables. The row type of the internal tables is a structure with the two substructures scarr and spfli that each have the columns of the two joined DDIC database tables as components. The substructures are resolved in a table comprehension in the output. The inline declaration of the third SELECT statement creates an internal table with a non-nested row structure. The components of the row are determined directly using the columns specified in the SELECT list.
