To enable the sync of workitems / stickies between ADO and piplanning.io you need to map:
piplanning.io Teams to ADO-Area paths
piplanning.io Iterations to ADO-Iteration paths
Mapping of teams to Area paths
Navigate to ALM Configuration
Edit the ADO connection you want to use
Navigate to the Team Mapping screen
On the team you want to map, click on "Add Area Path"
Enter the Area Path of this team in the input field
If you leave the textinput field (unfocus) it will check if the area-path is valid.
Multiple Area Paths
You can have multiple area-paths / team. This is useful if a team works in multiple value-streams (each Area-Path will than be a value stream)
Schema of Area-paths
You will need to include your root node into the path. Example: You have a ADO Project called "SAFe5.0". In that you will create the a path "Online Store". If you want to map to "Online Store", you will need to enter the whole path: "SAFe5.0\Online Store". Keep in mind that ADO uses backslashes "\" to structure the path.
