Edit SKU ID and Governed Product Attributes in WMS Product Master – Anchanto

Overview

Product Master protects a SKU’s key details while the SKU is in active warehouse operations. You can edit SKU ID and the governed product attributes while a SKU is Unassigned. These fields become read-only once the SKU is assigned to an active Inbound, Outbound, Stock Take or Order Processing activity. They unlock automatically once the operation is completed. The same rules apply in the Product Master UI, the API and Bulk Upload, so product data stays consistent from order creation through dispatch

Prerequisites for Success:

Requirement	Details
Access	Access to Product Master in WMS
Permissions	Attributes are editable as per existing user permissions
Configuration	None. The governance applies to all customers and can’t be turned on or off.

Governed Attributes at a Glance

Attribute	Editable when	Locked when	Unlocks when
SKU ID	SKU is Unassigned	SKU is assigned to an active operation	The operation is completed
UOM	SKU is Unassigned	SKU is in an active operation	Doesn’t unlock after GRN. UOM follows its existing GRN rule and stays locked after GRN, even when the operation finishes.
UPC/EAN	No active operational dependency	SKU is in an active operation	All applicable operations are completed
Price details	No active operational dependency	SKU is in an active operation	All applicable operations are completed
Dimensions and Weight	No active operational dependency	SKU is in an active operation	All applicable operations are completed

Operations That Lock Governed Attributes

Operation type	Stages covered
Inbound	Receiving, QC, Putaway
Outbound	Picking, Sorting, Packing, Dispatch
Stock Take	Active Stock Take activity
Order Processing	Active Order Processing activity

Step-by-Step Instructions

Create a SKU

Edit an Unassigned SKU

Step	Action
2	Go to Product Master → Open a SKU in the Unassigned stage → Update the SKU ID field if required and click Save → The SKU ID is updated. Once the SKU is assigned to an active Inbound, Outbound, Stock Take or Order Processing activity, SKU ID becomes read-only along with the other governed attributes.
3	Go to Product Master → Open a SKU that is Unassigned or has no active operational dependency → Edit the permitted product attributes and click Save → Changes are saved according to your existing user permissions.

View a SKU in an Active Operation

Step

Action

Go to Product Master → Open a SKU that is part of an active Inbound, Outbound, Stock Take or Order Processing activity → Governed attributes (SKU ID, UOM, UPC/EAN, Price details, Dimensions and Weight) appear as Read Only / Disabled, with the notification: “Product Update Restricted – This SKU is currently associated with an order undergoing warehouse processing. Product attributes cannot be modified until the applicable order processing is completed.”

Edit a SKU After Operations Are Complete

Step	Action
5	Go to Product Master → Reopen the SKU once all applicable operations are completed → Governed attributes are editable again, except UOM, which continues to follow its existing GRN rule.

Update Products Through the API or Bulk Upload

Step	Action
6	Go to the Product Create / Update API → Submit a request that changes SKU ID or another governed attribute → If the SKU is in an active operation, the request is rejected with an appropriate error.
7	Go to Product Master Bulk Upload → Upload your file → Each row is validated against the same rules. Rows for locked SKUs are rejected with a failure reason, and other valid rows are processed.

Important Notes & Limitations

Topic	What to know
Multiple active orders	If a SKU is linked to several orders, governed attributes stay locked while at least one applicable order is still in active processing.
Admin users	Operational restrictions apply to Admin users as well, unless explicitly configured otherwise.
Unknown operational status	If WMS can’t determine whether a SKU is in an active operation, the update is blocked and an appropriate error is returned.
Integrations	Product updates received from integrations are processed asynchronously and validated against the same rules.
Historical records	Product Master changes never modify historical order or transaction data.
Existing orders	Orders already in the system continue to process without any change in behaviour.
No on/off setting	This governance applies to every customer and can’t be enabled or disabled.
Not in scope	SKU ID generation logic, automatic creation of a new SKU to replace an ID change, marketplace-side SKU changes, and changes to the OMS product master.

Troubleshooting & Common Errors

If the system shows this error	Follow these steps to fix it
Product Update Restricted “This SKU is currently associated with an order undergoing warehouse processing. Product attributes cannot be modified until the applicable order processing is completed.”	Wait until all applicable Inbound, Outbound, Stock Take or Order Processing activities for the SKU are completed, then reopen the SKU and make your change. If the SKU is linked to several orders, every applicable order must finish processing first.
Governed fields are still disabled after operations finish (UOM only)	UOM follows its existing GRN rule and stays locked after GRN, even when the operation finishes.
API request rejected when changing a governed attribute	The SKU is in an active operation. Retry once all applicable operations are completed.
Bulk Upload row rejected with a failure reason	That row’s SKU is locked by an active operation. Other valid rows in the file are still processed. Re-upload the rejected rows once operations are completed.
