is it possible to change transaction code allocations after reconciliations

[CloverQ]

Hi @Mark1887 

Changing the allocation account in a reconciled transaction would make this transaction unreconciled, which in turn will throw the period it was reconciled in out of balance, and all the periods after that. You would need to undo reconciliation until the period it became out of balance, then redo bank reconciliation from then. 

Here is more details about fixing out of balance bank reconciliation, should you need.
