FM BCS FMDERIVE

Hi All,

We have a problem with account derivation strategy. I have configured fmderive as below. I think my configuration is not correct. Because i am getting an error in F-02. What sould I change in fmderive???

(  Account assignment change with document creation (See long text)!  Message no. FMUP127  )

Procedure

    Use transaction FMDERIVE to change the derivation of the FM account

    assignment so that, as early as the RWIN-event CHECK (which occurs

    before document creation in all components), the correct account

    assignments can be derived and it is subsequently no longer necessary to

    overwrite them. The error occurred in the line item 0000000001 for the

    G/L account 7700101001. The account assignment(s) FUND_CENTER are

    affected by this.

My rules are : Assignment : Derivation from cost center to fund center

source field : COST_CENTER  target field : FUND_CENTER

under condition tab,  name : COST_CENTER operator : <>   value : blank

Assignment : Derivation fund center for non existent line items

under definition tab : constant  : dummy   and target field : FUND_CENTER

condition tab : name : COST_CENTER   Operator : =  value : blank

Table Lookup   :  Duplication from GL account to commitment item

for SKB1, source fields are  company code and account number

for target field, skb1 - FIPOS - commitment item

Derivation Rule  :  Derivation fund center

source field : cost_center and target field : fund_center

condition tab : cost_center = blank

and rule values as below

cost center        fund center

SOL000001        SOLMM00001

SOL000002        SOLMM00002

Derivation Rule  :  Derivation commitment item

source field : account_number and target field : commitment_item

condition tab : account_number    =    blank

and rule values as below

G/L Account number        Commitment Item

7700101001                    7700101001

7700101002                    7700101002

Can anyone help me??

Thank you very much
