Hi Paulo,
Yes you understand correctly but there is more below
and I checked as you suggested, but WBS was optional in the field status group.
On further testing of settlement, This is getting weird:
a) I tested while having only cost on the WBS (CE Cat. "1") (Dr. or Cr. Balance). In all cases, the receiver G/L must be without cost element. If the receiver has a cost element, the system asks for cost object "which is not provided by settlement" --> That's OK
b) I tested while having only revenue on the WBS (CE Cat. "11") (Dr. or Cr. Balance). Same behavior as point a) which is OK too
c) I tested while having both revenue and cost on the WBS (CE Cat. "11&1"). The system demands that the receiver G/L must have a cost element. If I provide a receiver G/L that has a cost element (regardless of its category), the system demands I assign a cost object "which is not provided by settlement".
The result of point c) = No settlement can be executed due to errors.
d) I tried to separate things using source structure (one for cost and one for revenue). Settlement only works if the receiver G/L of revenue source has a cost element. And the receiver G/L of cost source has no cost element. And not the other way around.
The system assigns the WBS to the revenue receiver G/L account !!
The system doesn't do the same to the cost receiver G/L account.
Accordingly, revenues settled from the project are reported right back to the WBS element ! this also doubles the revenue after settlement in the "Hierarchical Reports" while keeping the revenue to the same amount in the "By Cost Element Reports" only changes the carrying cost element.
Help!
