Sales trade agreement prices and discounts can only be specified per product dimensions + site + warehouse. In standard D365FO pricing, all inventory dimensions can be activated to be price relevant. This includes the generic inventory dimensions InventDimension1 to InventDimension12 (https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/inventory-dimensions).

We would like unified pricing to provide the same flexibility and allow us to specify prices/discounts per all inventory dimensions (including generic dimensions).

Regarding standard inventory dimension this might most typically be needed for batch and maybe serial numbers.

An example for generic dimensions: There are customers that use one of the generic inventory dimensions to distinguish stock by item condition (New, Used, Refurbished). For them, this dimension is pricing relevant.
