Hello, I'm a beginner. How can I write my files into external database?

Is it correct?

Thank you!!

REPORT Z_AA.

tables: ZAATEST.

parameters: x type i.

data: workarea1 like ZAATEST.

data: table1 like table of workarea1 with header line.

workarea1-x = x.

append workarea1 to table1.

write: / workarea1-x.
