As an alternative to mapping PI point names, you can specify the unique PointID of the source point in this attribute of the target point. The advantage of this approach is that the mapping remains valid if the source point is renamed. Due to a limitation of the PI API, if the source point name is longer than 80 characters, you must use this approach to mapping.

If the PI Data Archive version is earlier than 3.4.370.x or the PI API version is earlier than 1.6.0.2, and you want to use a maximum ExDesc length of 1023, you need to enable the PI SDK. See PI SDK options for information.
