Obsolescence Control

Open: Stock Control > Stock Maintenance > Obsolescence Control

The Obsolescence Control screen provides a central location for managing stock items that are either planned for obsolescence or already obsolete.
This feature helps users identify, review, and replace obsolete stock items across Bills of Materials and Works Orders, while ensuring MRP behaves correctly when planning around obsolete components.

The Obsolescence Control screen contains two tabs:

Planned Obsolete Items

Displays all stock items marked as obsolete with a planned obsolescence date in the future.

Columns include:

Code – The stock item code.
Name – The stock item description.
Obsolescence Date – The planned date on which the item will become obsolete.
Superseded By – The replacement stock item, if defined.

Obsolete Items

Displays all stock items marked as obsolete with either:

An obsolescence date in the past, or
No planned obsolescence date specified.

This tab helps users identify items that are already considered obsolete and should no longer be used for planning or production.

Available Actions

Both tabs include the following actions:

Replace Component
Opens a Replace Component screen that substitutes the selected obsolete item with its superseding item across:
- BOM Components – Replaces the obsolete component on all BOMs (active versions only).
- Works Order Components – Replaces the obsolete component on live or entered works orders, following the same logic as the Component Tools – Replace Component screen.
View Item
Opens the stock item record in read-only mode for review.
Amend Item
Opens the stock item record for editing, allowing users to update or correct obsolescence details.
Stock Profile
Opens the stock profile enquiry window for the selected item.

MRP

When MRP runs, it analyses stock items marked as obsolete and behaves differently depending on the item’s obsolescence status.

Items Obsolete in the Future

When an item has a future obsolescence date:

MRP considers existing available stock and replenishments valid up until the obsolescence date.
After that date:
- If a Superseded By item is defined, MRP automatically switches future demand and replenishment to that replacement item.
- If no superseding item exists, MRP continues to forecast demand for the obsolete item but prevents users from actioning any recommendations beyond the obsolescence date.

Note: This may leave stock of the obsolete item in the system that can no longer be consumed. This is expected behaviour, as obsolete stock should not be used once the effective date has passed.

If all stock and replenishments are consumed before the obsolescence date:

MRP switches demand and replenishment to the Superseded By item (if defined)

If no replacement is defined, MRP continues planning for the obsolete item but stops recommendations from being actioned past the obsolescence date.

Items Obsolete in the Past

When an item’s obsolescence date is in the past:

If a Superseded By item is defined, all MRP demand for the obsolete item automatically transfers to the replacement item.
If no replacement is defined:
- MRP still raises a recommendation for the obsolete item, but users are prevented from actioning these recommendations.

This ensures that obsolete items are never inadvertently ordered or produced while preserving visibility of legacy demand that cannot be fulfilled.
