hi
if u have created ur own doc type without referring to std doc type then u have to carry out all customising related to doc type define/assign,item catg define/assign,sched lincat define/assign.in spro.
if u have created referring to sap std doc type with copy all data then system by default does all these .
In other words
Check if the combination of your sales order type and item category type exist.
In customizing you need to set up which item category types can be linked to the sales order types.
