2.1 Logon ke sistem SAP Netweaver Setelah anda selesai menginstal sistem SAP Netweaver (kalau belum, anda bisa langsung loncat ke BAB 12) dan membuat

system entry di saplogon (SAPGUI), coba anda logon dengan memilih system entry yg sudah anda buat dan lakukan double

click di mouse anda untuk menjalankannya, lihat gambar 2-1 dibawah ini.

Gambar 2-1 SAP Logon

Di screen berikutnya anda harus memasukkan Client, User-ID dan Password. Untuk Sistem SAP Netweaver test drive yg kita

gunakan sudah disediakan user account BCUSER dan password = minisap, masukkan data ini dan tekan tombol Enter di

keyboard anda (gambar 2-2), kalau logon berhasil maka pada screen berikutnya SAP Netweaver test drive siap digunakan.

2.2 ABAP Repository dan Object Navigator ABAP repository adalah kumpulan obyek-obyek komponen ABAP didalam database, obyek-obyek tersebut adalah: Table,

data element, program, function group, function module, class, dan lain-lain. SAP mengatur database berdasasarkan satu

field didalam database yang bernama CLIENT. Data untuk business object didalam aplikasi SAP seperti material master, cost
