In order to comply with a set of VAT tributary requirements I need to make the lines on the Item Requirement form on a Project to be Sales Tax inclusive, this works perfectly on Purchase Orders related to projects, for some reason the Sales Order do not.

We've contacted Microsoft and their answer was a simple "we just didn't get to it, now is too late and no there is no hoftix" so I summon you AX professionals to see if you have been presented with this issue and if you manage to fix it what did you do?
