In Fallout 4, there are a variety of junk items you can pick up, all of which give you scrap. This scrap is a critical resource in Sim Settlements 2, since it's used to build, upgrade, and maintain your plots.
Resources are stored in each individual settlement's Virtual Storage. As your settlers build, upgrade, and maintain plots and other assets within the settlement, they will pull resources from the Virtual Storage network.
With the release of Sim Settlements 3.0.0, an additional type of resources was added for Outposts called Supplies. Supplies include Ammo, Armor, Chems and Weapons that you can pick up and donate to the War Chest at the War Planner's Desk in your Outposts or at the City Planner's Desk in your Settlements.
¶ Resource Use Priority
The current use priority is:
If you are currently within a settlement's borders and the Virtual Storage doesn't have enough resources for the settlement to build/upgrade something, it will then pull from the Workshop storage, or the scrap in your inventory, to fill the gap.
If you aren't currently in the settlement and the Virtual Storage network doesn't have enough resources for the settlement to build or upgrade something, that task will not be completed. Additionally, if you aren't currently in the settlement and the Virtual Storage network doesn't have enough resources for the settlement to pay maintenance costs for an asset, that asset will break as though it were damaged in a settlement attack.

¶ Levels of Resource Complexity
There are three levels of complexity associated with scap in Sim Settlements 2:
Each level of complexity requires you to manage more specific types of scrap, increasing the difficulty of resource management as you go down the list.
At this level of complexity, all you need to manage is how much Scrap or Supplies of any type you have in your Virtual Storage. This is the easiest level of difficulty for resource management in Sim Settlements 2, and is recommended if you want a more hands-off settlement experience.
At this level of resource difficulty, you will need to manage how much Scrap you have in each of the 4 Scrap Categories and how many Supplies you have in each of the 4 Supplies Categories.
This is the hardest level of difficulty for resource management in Sim Settlements 2.
At this level of complexity, the 4 Scrap Categories are futher divided into 32 Scrap Components (shown below). You will need to manage how much of each individual component you have available in Virtual Storage for your settlement.
At this level of complexity, the 4 Supplies Categories are futher divided into 14 Supplies Components (shown below). You will need to manage how much of each individual component you have available in Virtual Storage for your settlement.
