I think :
1) FF Budget : Following Fiscal budget ( Really is Budget in Fiscal Year +2 : In this case 2014)
2) External Procurement : Actual Cost entered in materials with Val category : 415
3) Internal Activity : Actual cost entered in materials with Val category 600
4) Miscella: Calculated : Actual Cost - External procurement - Internal Activity - Stock issue
5) Funds Reservation : reserves done in Founds ( not sure how it is calculated)
6) Residual orden Plan : I think this value are cost plan entered in orders ( maintenance, production..), they are only takn in account when order is in status Released,, not TECO or CLOSED.
I hope this can be useful,
