Hi All,

I have a requirement, where I need to find the duplicate contact from dynamics and need to send the list of duplicate contacts to user.

All I have done, through the logic like first I have sort the output of list rows and then comparing(email column) second row to first and third to second and fourth to third and so on. So like this I got Unique and Duplicate contacts list.

But issue is that, Like I need to the all duplicate itmes inside the duplicate list but here it is giving one item in unique list and rest of the duplicate item in duplicate list.

for example: Array=[A,A,A,B,B,C,C,D,E] then it is giving

Unique Array=[A,B,C,D,E]

Duplicate Array=[A,A,B,C]

But It should be

Duplicate Array =[A,A,A,B,B,C,C]

Unique Array=[D,E]

Can someone please suggest me a way to achieve this ?

How to Eliminate duplicate items using power automate ?

Hi Partner,

You can just use two nested 'List rows' steps to achieve the purpose.

Please refer to the following steps:

1.List rows:

Note: click “Settings”, activate “Pagination” and set the “Threshold” to the maximum allowed value of 100,000. If you don’t take this step, your Flow will only check 512 records by default and probably won’t catch all of your duplicates.

2.Variabe to store the number of return contacts

3.Condition:

4.Update 'isduplicate' flag of the contact:

Then you can use this flag to specify records are duplicate or unique.
