Crm 2011 ile fetch xml kullanmak için ilk önce fetch xml i calısan javascript dosyamızı webresource lara eklememız lazım.Bu javascript dosyasını sayfanın altında bulabilirsiniz.
Asagıda kullanıcının takımlarına gore işlem yapan bir javascript fonksıyonu vardır.İlk once fetch xml yoluyla kullanıcının takımlarını alır daha sonra ıslemımızı yaparız.
Not=Eklediğimiz fetch xml i calsıtıran javascript dosyasını formumuza eklemek zorundayız.
