Every year, it's time for the turn of the year in SAP Business One. Everything you do only once a year is of course little practiced. That's why we've put together a small series on year-end closing in SAP Business One. Without claiming to be complete, it should be a little support for the rare routine year-end closing in SAP Business One.

1. posting periods at the turn of the year in SAP Business One
Please remember to start the new financial year (i.e. new Posting periods) in good time.
You can find the booking periods in:
Administration → System initialization → Posting periods

SAP Business One posting periodsNote: please remember to set the due date of the new periods in the future, depending on your payment terms beyond the new year. Otherwise, SAP Business One will not be able to determine net due dates of invoices beyond the current year. In new versions of SAP Business One, you can use the "create new periods with due date until next fiscal year" option for this purpose:

SAP Business One "New Period...If your version of SAP Business One does not include this feature yet, please enter the "Due date by" manually when creating new periods - see further steps.

2. blocking posting periods in SAP Business One
To avoid misunderstandings:
There is no month-end closing run or similar in SAP Business One.
There is a period-end closing, but it is performed purely at the fiscal year change for the year-end closing.
As mentioned, there are no month-end closing transactions in SAP B1 and they are not necessary, so you should definitely refrain from using them, ending balances of the accounts at the end of the month as a carryover to the new month! The balances are presented automatically.
Nevertheless, it may be necessary to make adjustment postings at the end of the month for the (flat-rate) stock value correction or other corrections. However, these are normal journal entries that must be created manually if necessary.
At the latest with the printout of the monthly income statement However, you should „close off“ the system so that no employee can subsequently book anything into this closed month without your knowledge.
And that's exactly what every posting period (= month) the two fields "active" and "blocked"
- Call via "Administration >System initialization >all settings >Posting period> orange arrow of the desired period".
- Assign the required status to the posting period:
„Unlocked“- all users can book all types of transactions and documents in this period according to their permissions. This status is assigned to new booking periods by default.
„Unblocked except sale“– all users can book all types of transactions and documents, with the exception of documents in the Sales module, in this period according to their authorisations. Assign this status after the period has expired if there are still purchase documents, such as late incoming invoices, and other transactions open that need to be booked for this period.
„Period-end closing“- only users with full period-end closing authorisation can post all types of transactions and documents in this period. Assign periods this status when the period has ended, all late transactions have been posted and only the annual closing process remains.
„Locked“– in this period, neither documents nor transactions can be posted. Assign this status to the period after all adjustments have been posted and the financial closing process for this period is complete.
