Hello,
We generally use for WBS Ra key S0001 method 14 RRB (resource related billing).
Normally when you have costs in progress on WBS (not yet invoiced), the system calculate a wip at the
end of the fiscal period (KKAJ).
I you make an invoice (with DP90) for this costs at the next period, the system must cancel the previous wip and put the costs in the status COS ( cost of sales ).
Since we migrate from 4.5b to ECC6 we have big problems because invoices don't cancel the wip
anymore.
Can you help us?
