This template provides a simple means of copying one object to another. Enter a source and destination object. The source will be copied to the destination object any time the source object's value is updated (by a client read rule for example).

Delete will remove the rule number shown in the "Showing" box. Insert will insert a new rule before the rule number shown, and is used for placing rules between existing rules. It is not necessary to use Insert to add rules to the bottom of the list or to define any rule presently having zero for a source object.

Entering zero as a source object effectively deletes the rule even though it will still appear in the list until deleted. Unused rules at the end of the list will always show zero as the source object. If you wish to prevent these from being displayed, reduce the number of rules enabled.

The number of rules enabled simply limits the scope of rule review so that you do not have to review a lot of unused rules.

A note about multiple copy rules from a single source: Each object is allowed to propagate only once to avoid redundant transmission of data. Therefore, to copy the same source to more than one destination, copy the objectss in sequence. In other words, rather than copy A to B and A to C, you should copy A to B, then B to C.
