When the end of the year arrives, it is usual to change the numbering of invoices and credits of purchases and sales in Dynamics NAV or Navision. Although this change is not strictly necessary to make it on January 1, it is true that most companies put these counters to 0 on this date. If this is the case of your company, in this article we indicate the steps to follow to do so.

For each one of the series of Sales invoice, Sales receipt, Invoice purchase and Purchase credit, we will create a new line with the numbering to be taken as of January 1 of the new year.

Steps to follow in Dynamics NAV

Access the Departments menu / Financial Management / Configuration / Administration / Nos. Series, and we position ourselves in the series that we want to modify and select Lines:

We created a new line with initial date 01-01-20xx keeping a correct order:

From this step, depending on the date of the document to be registered, the numbering corresponding to the date we have set on the date of work will be selected.

Remember that if you have activated the restriction of allowed registration dates, you may have to check them at the beginning of the new year.

If you have several users, you can define it for each user, from Administration / Application Configuration / Users / User Configuration:

If you do not have users, you can restrict the registration dates allowed from Departments / Financial Management / Administration:

Finally you can create a new exercise from Departments / Financial Management / Configuration / Accounting Periods:
