Why (Vertex Product Code-VVTC) is generated in F4812 but is not passed to F4822??

Hi guys,

We are using Rental Management Module and we have some issues with the Tax Calculations,  we are using Vertex Q series but we found that the tax calculations are wrong,  Looks like set up in JDE Eone is correct, but just catch my attention that the Product Category code is being populated in F4812 but is not being populated in F4822, we are using report R54R300 to generate F4812 and R48121 To generate F4822.  Is there any reason why the (Vertex Product  Category Code) is not passed to F4822, because the Vertex is configured to use it
