Product is a Read/Write Variant property that describes the product involved with this batch object. Changes to this property are stored on the Server as well as in the in-memory representation of the object.
The object placeholder is an object expression that evaluates to an object in the Applies To list.
This property can be a string or numeric VARIANT. It can also be set to a PIModule. This allows you to use PIModule's to store product information.
The Product may be left blank, but if it is a string, it must follow these rules:
1. No control characters are allowed; such as linefeeds or tabs
2. The following characters are not allowed:
* ' ? | ` "
NOTE: If you store a PIModule in this property with PI 3.3SR1, searching for batches by specifying a mask for this property will fail. This will be fixed in a future release of the PI Server.
