TABLES parameters are obsolete!

What causes this issue?

TABLES parameters are table parameters. Table parameters are obsolete
CHANGING parameters that are typed as internal standard tables with a
header line. If an internal table without a header line or a table body
is passed as an actual parameter to such a formal parameter, an empty
header line is generated in the function module. If an internal table
with a header line is used as an actual parameter, both the table body
and the header line are passed to the function module. In the case of
formal parameters defined with TABLES, no value transmission is
possible.
Formal parameters defined with TABLES can be replaced by formal
parameters defined with CHANGING. A local work area can be created in
the function module for the internal table using the addition LIKE LINE
OF itab of the DATA statement in the function module.
