We have to charge our customers for consulting and the number of hours to be charged can vary depending on the project.
How can I create a material/service so that it has confirmations associated with it? Which material type should I use?
I do not want to use DIEN as it does not allow posting of confirmations.
Please help me out.
It sounds like you are trying to create Customer Service order in PM which allows you to create confirmations and then billing to your customers.
With Customer Service Order (PM order type SM02), you don't need to use material masters (just one reference material needs to be created for config). The confirmations are against labour.
Hope this helps.
