AspDotNetStorefront doesn't enforce a unique constraint on SKUs or part numbers, so we don't use those as qualifiers for determining a unique product or variant. You could modify WSI to use these (if you have source code...would be a fairly simple modification), or you could simply use a query/sql node instead. For example, if you want to update variant 26 that has the SKUSuffix value of 10GALMP you could use this
Code:
<AspDotNetStorefrontImport Verbose="false">
<Transaction>
<Query>
<SQL>
<![CDATA[
update dbo.ProductVariant set Inventory=100,Price='200.25' where SKUSuffix='10GALMP'
]]
</SQL>
</Query>
</Transaction>
</AspDotNetStorefrontImport>
