For every range-type item you can specify inter-item dependencies using the Dependencies tab of the work item editor.
You can link items together using the following link types:
|How it works|
|Includes / is included in||If an item A includes item B it means that item B is included in the scope of item A. Portfoleon will check that timeline of item B is within the boundaries of the timeline of item A. _Includes / is included_ in is different from _Parent / child_ dependency in the following ways:One item can be included in many items, while an item can only have one parent.There’s no total effort rollup with _Includes / is included in_, while with _Parent / child_ all totals are rolled up to the root parent.|
|Predecessor / successor||The predecessor must finish before the successor starts.|
|Starts before / starts after||Item A must start before Item B may start.|
|Finishes before / finishes after||Item A must end before Item B may end.|
