we are using BAPI_COSTACTPLN_POSTPRIMCOST for doing cost element planing for wbs elements. Now there also exists transaction RECOPLCST02 for doing cost element planing RE-FX objects, e.g. business entity. Now I want to do the planing also for these objects. How can I do this? BAPI_COSTACTPLN_POSTPRIMCOST only allows cost center, wbs and order for planing but no RE-FX objects.
