FM error while saving posting for FB60

Question

Dear all,
i have implemented FM in ecc 6 ver ,while doing FB60 i got the below error.
FM account assignment SPML/DUMMY cannot be posted in posting ledger 9A
Message no. FMBS123
Diagnosis
The budget structure settings do not allow posting to the FM account assignment  SPML/DUMMY. The check of the budget structure ended with the return code 4.
The system recognizes the following return codes for the check of posting addresses:
u2022     Return code 1:
The check of posting addresses is switched on. However the FM account assignment SPML/DUMMY  is missing in the budget structure. Insert this account assignment in the budget structure for the posting ledger 9A.
u2022     Return code 2:
The check of posting addresses is switched off, but the validation of posting addresses does not allow posting on this address.  Check the implementation of the Business Add-In (BAdI) Validate Budget and Posting Addresses in BS.
u2022     Return code 3:
The FM account assignment SPML/DUMMY leads to a conflict when you define a grouping key within the context of the budget structure. Check the implementation of the Business Add-In (BAdI) Define Grouping Key.
u2022     Return code 4:
The derivation strategy used for deriving the budget address from the posting address derives an invalid budget address. You can use the program for displaying of budget structure settings to find out which derivation strategy is used. Check the Derivation Strategy for BudgetAddresses in Customizing. This error may also be caused by inconsistent customizing of active FM account assignment elements in BCS and FM. This can be checked in IMG activity Activate Account Assignment Elements in Budget Control System.
System Response
Processing stops.
Procedure
Check the budget structure settings according to the given return code.

Answer 1

Hi,
Two things:
a) FMDERIVE is relevant for both former and BCS models. It's a strategy which derives FM objects (not address) for postings of the document which have to be assigned to FM (basically, most of FI and LO documents).
b) Strategy for derivation of budget address is something different. Here, you can tell the system where you want your budget to be checked. For example, the posting goes to fund centre X (either by direct entry or via derivation strategy put in FMDERIVE), but the budget to be checked is on fund centre Y. This functionality could be also achieved with AVC controlling objects, but since you work with budget structure, it's more natural to do it there. If your posting and budget entries are on the same level, then you basically don't need the budget address derivation strategy at all.
