Accounts reassignments during commitment carryforward

Question

We had change in organizational structure and now need functional restructuring during year change operations.
We want to make account reassignments with the carryover.
If in the Customizing of Funds Management I have defined that commitment carryforward and budget carryover are possible.
Account assignment change is allowed during the commitment carryforward of purchase orders.
Strategy for Reassignment with relationships of the u201Coldu201D to the u201Cnewu201D account assignment is made.
And now I ran FMJ2 to do purchase order carryforward.
But it appears to have ignored the assignment change, and ignored any subsequent activity applied to the new assignment.
Assignment stay as it was.
Has anybody else enountered this? Can anybody tell me what may be causing this, and how to fix it?
Thank you.

Eli, thank you very much!))
Now derivation strategy for reassingnment works! But it works wrong - I don't understand where I made a mistake.
Let me describe my derivation for reassignment.
I have 4 steps. In first three I initialyze:
1. Initialization of commetment item - Derivation performed successfully. Value before:1, Value after: (blank)          
2. Initialization of Fund - Derivation performed successfully.  Value before:3, Value after: (blank)     
3. Initialization of Fund center - Derivation performed successfully.  Value before:7, Value after: (blank)     
4. Derivation rule, with simple rule value, for example: 1/3/7(source fields)=1/3/1(target fields) -  Derivation not performed. Reason:source field contains no value.
And now I have 2 mistake messages in FMJ2:
The value BLANK/SPACE is not valid; acct assgmt element Funds Center (strategy for reassignment) - Message no. FMCF803
The value BLANK/SPACE is not valid; acct assgmt element Commitment Item (strategy for reassignment) Message no. FMCF803
