Hi,
Are those vouchers created manually (M function group) or generated by the system?

the vouchers were created by system.

if possible, we need to delete them.

Hi Nagah,

if they are systemwise created a deletion will most probably imbalance one of the subledgers.

From my perspective the most practical way to solve this is:

1. Open old Period(s)
2. Post the voucher(s)
3. Create manual voucher(s) to reverse the impact from the posted voucher(s) in the old period(s)
4. Create manual voucher(s) for the impact from the posted voucher(s) in the old period(s)  in the an actual period that can be used for posting.
5. Investigate the postings and impact caused by the voucher(s) in the actual period

Kind regards

Ralph

when I was trying to open the financial period, system raised error (financial year is blocked in the main calendar).

You can reopen closed accounting year, if required (option in accounting year heder)
