Hi;

There is a setting in the Site/ Manufacturing  “Auto Build Tracked Structure” this will automatically assign the reserved components to the Shop Order Tracked  Structure Automatically. 

Prior to receiving the main part into inventory, if the Shop Order Tracked Structure does not reflect the actual situation then we can manually modify the Shop Order Tracked  structure by add or remove component functionality provided in the Shop Order Tracked Structure.

Alternatively possible to use Handle Structure By Barcode function for this purpose by selecting the required Node in the Shop Order Tracked Structure and Proceed.

After the item is received in to Inventory, it is possible to use Rename to a new part/ new Serial or Disconnect from Parent from Part Serial Page.

@mmoss If you detect that the as-built structure is incorrect after you have already received the products into stock, you can unreceive the product back to the shop order which will make the tracked structure editable as Dameenda explained above.

A multilevel repair shop order can also be used to modify (or rather create a new revision) the as-built structure.
