Item Type in Non Catalog Requisition page

Summary:

Hi,

On Request Non Catalog Items page , item type " Goods Billed by Quantity" by default is mapped to Line Type Goods. We have a custom line type with basis as Quantity and created a custom doc style exclusively with this custom line type and respective CPA type.

Now , when a non catalog requisition is raised with item type " Goods Billed by Quantity" , its not picking up the CPA and creating respecting PO with custom line type. Instead by default it is getting mapped to "Goods" line type. How do we sort this issue either at requisition page itself or during PO creation?
