| | 33 | SetSku() is normally called only once by the system.\r |
| | 34 | \r |
| | 35 | For each item (token), the database can hold a single value that applies to all SKUs, \r |
| | 36 | or multiple values, where each value is associated with a specific SKU Id. Items with multiple, \r |
| | 37 | SKU-specific values are called SKU enabled. \r |
| | 38 | \r |
| | 39 | The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. \r |
| | 40 | For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the \r |
| | 41 | single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the \r |
| | 42 | last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token, \r |
