/**

|
Sets the SKU value for subsequent calls to set or get PCD token values.
|
|
|
|
SetSku() sets the SKU Id to be used for subsequent calls to set or get PCD values.
|
|
SetSku() is normally called only once by the system.
|
|
|
|
For each item (token), the database can hold a single value that applies to all SKUs,
|
|
or multiple values, where each value is associated with a specific SKU Id. Items with multiple,
|
|
SKU-specific values are called SKU enabled.
|
|
|
|
The SKU Id of zero is reserved as a default. The valid SkuId range is 1 to 255.
|
|
For tokens that are not SKU enabled, the system ignores any set SKU Id and works with the
|
|
single value for that token. For SKU-enabled tokens, the system will use the SKU Id set by the
|
|
last call to SetSku(). If no SKU Id is set or the currently set SKU Id isn't valid for the specified token,
|
|
the system uses the default SKU Id. If the system attempts to use the default SKU Id and no value has been
|
|
set for that Id, the results are unpredictable.
|
|
|
|
@param SkuId The SKU value that will be used when the PCD service will retrieve and

set values associated with a PCD token.
