I'm trying to creare the settlement rule in a plant maintenance order, starting from a WBS element, using the BAPI_ALM_ORDER_MAINTAIN.
When I execute it, I receive the error:
"Cost element does not exist in controlling area".
In IT_SRULE I inserted the objnr of the order, the settlement type and the WBS element. I don't know what is the issue, If i try to close the order by IW32 transaction, with the same WBS, the settlement rule is created without problems and the order technical completed.
