Hi,
I am using the Process Builder6.5sp2.
According to the user guide we can use the New Case from Template and apply the folder template ACL to child.
the option is as :
You can choose to have the all objects in the folder use the folder ACL by selecting Propagate ACL to Child Objects.
I am not able to view the option in my Process builder.
Please find the attachment containing the screen shot of New Case From Template properties.
Kindly suggest if any configuration need to be done.
