Hi Everyone,I am seeing something strage,I am trying to create a master detail relationship between two abjects the child object has existing data,so i tried 2 ways1. created a lookup field,populated data in the records then tried to change the field type as master detail ,but no luck,then 2. i have deleted all the records of the object on which i am trying to create a master detail relationship and tried to create a new master detail field but either ways i am seeing the error "you can not create M D on existing data,i wonder where is the existing data when i have deleted all the records myself that too 1st i have deleted records in one object and then in both the objectsi have successfully M-D relationship lot of times but dont know why i am unable to do this now.NOTE: i am not sure if this helps for your reference or not, i have only one standard name field and 1 custom lookup field on the object on which i was trying to create a M-D relationship,however later on i even tried after deleting all the records and that lookup field too and then tried creating a new M-D field because the object no more having any data but no use in all the ways i am seiing same error
