Hi Maheswaran,
May I know the purpose of including Billing Form in characteristics of DIP profile
If you use Billing Form (01) in service order, along with your DIP profile, you can achieve your requirement of having Quotation cost to Debit Memo Request
It is not necessary to create again DP90, unless you want to have actual cost in the Billing Request
Once you accept the Quotation created through DP80, Debit memo request is created with the Price copied from Quotation
I have never come across Item category determination error at service order, could you provide me Message no for further analysis
thanks
