I have a flow that creates a planner task when I create an new item on sharepoint, I would like another flow to register on this planner task some details when this item is deleted on shapoint.

Hi @Anonymous 

First of all you need to save the ID of SharePoint item in planner task.

I recommend to save the task in planner with Title =  ID - SharePoint Title.

Next you'll build your flow with "When a item is deleted", this action don't brings all item information, it's bring only ID and deletion information (How delete, when deleted and etc).

Your flow structure need to:

• List all planner tasks
• Use a condition to see if Task Title has the ID
  • I use the condition 

    first(split(items('Aplicar_a_cada')?['title'],','))

• Update Task details (to add how and when deleted)
• Update Task ( change status)

See the print bellow:

• Lets say your data is in ListA.
• Create a list called ListB with following fields Title, PlannerID
• When item is created in ListA use your existing planner creation flow to create an item in ListB set Title=ListA.ID and PlannerID to the PlannerTask created by your flow.

Then on your deleted item flow, query ListB where ID eq ListB.Title and then delete the PlannerTask by ID and also the list item.

Although you are storing a extra list of data, it is completely maintained by flow and you do not need to be restricted to what the title is called, and most likely your users will break your logic with the above method as they will rename things to make them more user friendly.
