# Product Monitoring Features
P4W system provides tools to monitor and record every action concerning the products whether it is initial product creation, editing, receiving, moving, etc.
## Changes
This section represents full log of the product starting from its creation date and finishing with the latest edit. Changes only reflect product details and not warehouse operation with said product (e.g., receiving, picking, shipping, etc.)
Events column represent the log of every modification that was made to the product. 'Details' sections shows exactly the nature of the event, user who is responsible for the new log entry and the exact timestamp, as shown above. Finally, 'Changes' table list what exactly has been added/edited in the product.
{% hint style="info" %}
Notice: Only updated changes will be reflected in the event table. Changes are not saved automatically.
{% endhint %}
## Notes
This tool allow users to create notes concerning the chosen product. To create new note for the product click 'Notes...' link from the product page and chose 'New note' option in the bottom right corner of the new widow.

{% hint style="info" %}

Finally, notes can be deleted by clicking 'Remove' button from 'Action column'.
