Hi, 

Sorry, but not at that point for the automatically created vouchers such as the purchasing transfer voucher type 0.   Typically, the voucher creation would have failed during the transfer due to the period being closed.  Typically the user group period would have been closed and the transfer failed.  At that time, a modify date applied could set the appropriate voucher date.  This happens before your at that that point where the voucher was created. 

To help - in the future, it would be helpful; to have different user groups for operations and finance, and then ensure the transfer is done as an operations user so that when you close the period for operations, the transfer would fail.  You would then decide to transfer again using a finance user where the period is still open or do the modify date applied.  In any case, we want to find the issue earlier. 

Sorry, 

Wish I had the magic button. 

Best regards, 

Thomas
