How to check work items duplicates

[Anonymous]

Hi! This is my flow:

My flow works like this: 
1. I am create Work Item in Azure Boards;
2. Change "State" from New to Work 1;
3. Power Automate create child tasks.

Everything work fine, but i have one problem. When i edit my work item (First Step) this flow started automatically running and i have a lot of duplicates... How i can configure my flow so that duplicates are not created ?

Hi @Anonymous , 

Few things to consider:

1- You need to check if the current work item that has been updated already has an existing child task

2-If yes, then do terminate flow

3-If no, then create the child task 

I tested it and it worked for me so let me know if any further help needed

please follow these steps

1- create a new compose 

2-click on "input" then Expression and type Length 

3- switch to dynamics tap and add "value" , then hit ok

the compose should have this new expression length(outputs('Get_work_item_children')?['body/value'])

Could you also tell me how to filter duplicates by unique name? In your example, the task looks at whether there is an Epic, is it possible to configure the task to look at whether there is an Epic with a unique name, or just a unique name?
