Hi SAP Forum Members

Just wanted to understand th cost DP91 concepts.....all the data for the expenses costs based are taken from the costs elements.

Can you please tell me with respect to CAT2 and PR05 transactions Time and expense postings

How is the Expense type determing the costs elements which in turn are determining the materials

2. The Time and expenses are posted to a WBS elements how is the diffrerent costs elements are dertermined for example air tickets other overheads for expenses.

3. When we have the costs in EK01 condition type in SD .....in this procedure do we do costs elements accounting what is the difference from the cost center accounting

4. Any details on the Billing requests editor?

Thanks a Lot !
