# SYS\$1LOAD\$1HISTORY
Gunakan SYS\$1LOAD\$1HISTORY untuk melihat rincian perintah COPY. Setiap baris mewakili perintah COPY dengan akumulasi statistik untuk beberapa bidang. Ini berisi perintah COPY yang berjalan dan selesai.
SYS\$1LOAD\$1HISTORY dapat dilihat oleh semua pengguna. Pengguna super dapat melihat semua baris; pengguna biasa hanya dapat melihat data mereka sendiri. Untuk informasi selengkapnya, lihat [Visibilitas data dalam tabel dan tampilan sistem](cm_chap_system-tables.md#c_visibility-of-data).
