It's to define dynamically an internal table, the variable DY_TABLE is a generic DATA:

DATA: DY_TABLE TYPE REF TO DATA.

So u can't direclty work on it, but it needs to use a field-symbol:

FIELD-SYMBOLS: <DYN_TABLE> TYPE TABLE.

ASSIGN DY_TABLE->*  TO <DYN_TABLE>.

Now the table <DYN_TABLE> is without headerline, so it needs to use a workarea to read it:

DATA: DY_LINE TYPE REF TO DATA.
FIELD-SYMBOLS: <DYN_WA> TYPE ANY.

* Create a workare for <DYN_TABLE>
CREATE DATA DY_LINE LIKE LINE OF <DYN_TABLE>.
ASSIGN DY_LINE->* <DYN_WA>.

It can do the same thing while looping <DYN_TABLE>

LOOP AT <DYN_TABLE> ASSIGNING <DYN_WA>.
ENDLOOP.
