Katana uses inventory period closing to lock past inventory data, preventing changes that could affect financial reports or stock records. This ensures that previously reported numbers remain consistent between Katana and your accounting system.
Why are inventory periods closed
Prevents changes to past inventory quantities or values.
Avoids recalculations caused by Katana’s moving average cost method.
Keeps historical reports accurate and reconciled with accounting.
Open vs. closed inventory periods
Term | Definition |
Open period | The current month and the previous month. |
Closed period | All dates on or before the inventory closing date. No changes allowed to stock-affecting documents. |
Example:
If today is May 15,
Open period = May & April
Inventory closing date = March 31
On June 1, the closing date will advance to April 30.
Where to find the closing date
Go to Settings > Costing to view the current inventory closing date.
What’s locked in a closed inventory period
Once a period is closed, you cannot create, update, or delete documents that change inventory quantities or average costs for that period.
Affected areas:
Purchasing:
POs with a Received date in a closed period cannot be changed back to “Not Received” or have their date/extra costs edited.
You cannot select a closed period date when receiving items.
Sales:
SOs with a Picked date in a closed period cannot be reverted to “Not Shipped” or have their date changed.
You cannot select a closed period date for picking.
Manufacturing:
MOs with a Done date in a closed period cannot be changed.
A MO in an open period cannot have its date moved into a closed period.
Partially completed MOs cannot have their Completed date moved into a closed period.
Stock adjustments:
Adjustments with an Adjustment date in a closed period cannot be edited or moved into an open period.
Stock transfers:
Transfers with a Transfer date in a closed period cannot be changed.
You cannot select a closed period date for a transfer in an open period.
Manually changing the inventory closing date
You can move the closing date back up to 18 months from the current date.
Manual changes remain in effect until the next automatic monthly closing.
Moving the date forward won’t reopen a closed period.
Changes to past documents will trigger recalculations for all related stock items.
Important notes
Always consult your accountant before changing the inventory closing date.
Changes to previously closed periods can cause unwanted recalculations and inconsistencies.
Only adjust the closing date when you fully understand the accounting impact.
Result: Understanding how closed inventory periods work helps you protect historical data, maintain consistent financial records, and comply with accounting best practices.
