Configuration for using DP90 transaction

Hi All,

I want to use the DP90 transaction for creating resource related billing requests. I want to know what configurations i need to make for this.

I have searched and found some points:

1. Assign WBS element for the sales order item in Account Assignment Tab.

2. Define DIP profile for the sales order item in Sales B tab.

3. System Settings for Resource-related Billing - Billing - SAP Library

Is there any other settings or configuration i need to make to use resource related billing.

Thanks in advance,

regards,

NarsiReddy.
