Specifying the packages used to generate an allocation matrix (SysML)
By default, a new Allocation Matrix searches for allocated items in the Package that owns the Allocation Matrix. You can specify which Packages to search for allocated items or alternatively search the whole model.
To specify the packages used to generate an allocation matrix:
1. Right-click the Allocation Matrix, and select Links > Analyzed Packages.
2. For each Package you want to use to generate the Allocation Matrix:
a. In the Link Items pane, select the Package.
b. Click the Link button.
If you want to use all Packages in the model, click the Unlink All button.
* 
Generating an Allocation Matrix for all items in a model may take some time.
3. Click OK.
