I have lookup relationship between 2 objects.if i delete the parent record i don't want to delete the child record also .how can i do this??In my case Assigment is parent object and and time card is child object.
In Lookup Relationship, if Parent record is deleted child record never get deleted. Instead to achieve this, we have to write the Apex Trigger on Parent object to delete child record if Parent record is deleted.
Whatever you asked is the default functionality of lookup relationship. You need not make any changes.
If you want opposite child record also need to be deleted then let me know I will share the Apex Trigger to do so.
Since i cant locate an edit option in lookup field as it is part of managed package.So limited scope of editing.
