What is a work area in ABAP?

A work area is a structure used specifically as a temporary holding spot for a single row while reading from or writing to an internal table (or a database table) — conceptually, it's "the current row you're looking at" during a loop or a single-row read.

DATA: ls_work_area TYPE kna1.

READ TABLE lt_customers INTO ls_work_area
  WITH KEY kunnr = '0000001234'.

WRITE: ls_work_area-name1.

Work areas are especially central to classical ABAP's LOOP ... INTO and READ TABLE ... INTO patterns, where each iteration copies one row of the internal table into the work area for processing. Modern ABAP syntax (using inline declarations like LOOP AT itab INTO DATA(ls_row)) still uses this same underlying concept, even when the work area variable is declared inline rather than upfront.
