The Period Closing Voucher (PCV) is the document you submit to close your books at the end of a financial period. When you submit it, ERPNext moves all your Profit & Loss balances into the closing account.



> Accounting > Accounts Settings 

In Accounting Settings, go to the following tab and field to enable Legacy Controller

>  Accounts Closing (tab) > Use legacy controller for Period Closing Voucher

If your company has a very large amount of General Ledger Entries, this closing process can take a long time and sometimes it gets stuck. This setting decides how ERPNext runs that closing process, so you can avoid the timeout.



##### **What happens when it is** enabled **(checkbox ticked) Legacy behaviour**

- The entire Period Closing Voucher is submitted in one single database transaction.
- Everything is processed together, in one go.
- This is the older, default way of doing things and works perfectly fine for small and medium sized general ledgers.
- If ledger entries are in large volumes, this single big operation can time-out and fail.
- For reverting balances, this approach only considers the main Account (ledger). It doesn’t split the reversal entries based on Accounting Dimensions tagged in the ledgers, hence makes the posting efficient.

##### **What happens when it is disabled (checkbox unticked) Batched behaviour**

- The closing is broken up into smaller batches.
- Each date in the closing period is processed as its own separate background job.
- Because the work is split into small pieces, the submission won't time out, no matter how large your ledger is.
- The processing runs in the background, so it can take a few minutes to complete, but it completes reliably.
- This honours reversing of ledger balances based on dimensional postings.



This is an opt-in feature. Most businesses can leave the box ticked (enabled). If you have a general ledger entries in the large volumes and PCV’s closing is taking much time, simply untick the box (disable it) to switch on the safer batched processing.
