Fonksiyonel ve teknik danışmanların projelerde en sıkıntılı konularından biri de tablolar arasındaki join konusudur. Aşağıdaki kod yapısnı SE38 işlem kodundan aktif hale getirip birden fazla alan adını girip ortak tablolarını bulabilirsiniz.
Bu çözüm sadece tablolar için geçerlidir.
Seçim ekranına bulmak istediğimiz alanları yazıyoruz.
Çalıştır dediğimizde ALV olarak ortak alanların olduğu tablolar sıralanıyor.
