India localization allows using either cost price or transfer price when transferring goods between warehouses. Transfer price can be specified in released product. If product dimensions are used, transfer prices must be specified separately for each product dimension combination.

There is also data entity which can be used to import transfer prices, however this data entity doesn't support product dimensions as primary index of staging table is too restrictive. One item can exist only once in import job. Workaround is that transfer prices must be split to different Excel sheets, one sheet per released product and product dimension. Each combination must be imported with separate import job. If one item has 10 different product dimensions, then 10 different import jobs are needed.

My proposal is to change primary index of staging table to contain also product dimensions.
