| | 51 | Sets the SKU value for subsequent calls to set or get PCD token values.\r |
| | 52 | \r |
| | 53 | SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values. \r |
| | 54 | SetSku() is normally called only once by the system.\r |
| | 55 | \r |
| | 56 | For each item (token), the database can hold a single value that applies to all SKUs, \r |
| | 57 | or multiple values, where each value is associated with a specific SKU Id. Items with multiple, \r |
| | 58 | SKU-specific values are called SKU enabled. \r |
| | 59 | \r |
| | 60 | The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255. \r |
| | 61 | For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the \r |
| | 62 | single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the \r |
| | 63 | last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token, \r |
| | 64 | the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been \r |
| | 65 | set for that Id, the results are unpredictable.\r |
