This idea is an extension of splitting of Fixed Assets Functionality.
My current employer has a business process where IT team can create a Purchase Requisition of Fixed Assets, which is approved by Procurement Team.
However it is additional task for Procurement right now to edit the already Approved Purchase Order line to add Fixed Assets Functionality in PO line. And then to split the lines as they are acquiring multiple Fixed Assets and want to create multiple Fixed Assets Lines in Fixed Assets Module.
In this case Fixed Assets Functionality is associated during the time of Purchase Requisitions Creation as well as the Fixed Assets are split in Lines which same can be carried forward to Purchase Order Lines.
Fixed Assets are created in the system either during the time of Product Receipt or Invoice which will not change anything in the Fixed Assets Module.
