Incremental Number related to different variables

Hello all,


I am trying to use Power Automate to simplify an order processing. A customer can submit a request via Microsoft Forms and the corresponding data is stored in a list. See the process below. Up to this point everything works fine.




The short version of the list looks like this:


The title is generated from the request year, the country of destination and the test item. There are different country codes (e.g. UK, US. EGY...) and 5 different item categories (10, 20, 30, 40, 50)

As soon as a new item is added, an approval process should get started. I started the flow like this: 





If this request is now approved, the title already created should be given an incremental number. For the above example, the following should apply after approval: 2022-UK-10-0001.
If another request is now made for "UK-10", this should receive the number 2022-UK-10-0002. If then again a first request is made for "US-10", this shall receive the title 2022-US-10-0001 and so on. The numbering should therefore depend on the country of destination and the test item category.  Subsequently, a folder should be created in another library, which contains the updated title of the request.

If the request is rejected, the title remains the same and just a change of status is made. Hope the problem became clear. 


I have now tried many things and also searched some threads, but unfortunately I did not find a suitable solution. Maybe some of you Power Automate-Pros can help me out!


Many thanks in advance! 


Best regards

Here is the solution of @Pstork1 who send me a private message. Much appreciation for his help!


OK, your flow triggered by the creation of a new item is fine until you get to the Get Items.  The Get Items should look like this



That sorts and filters the output of the get items.  The concatenated value used in the filter is the following


that's the Title from the trigger (something like 2022-UK-10) with a - appended to it.  That will give you all the records that have already been changed for that category.  Like 2022-UK-10-100 or 2022-UK-10-100  but not 2022-UK-10.  Since they are sorted in descending order you need to get the number off the end of the first record in that list.

2) Next comes a condition to check whether any records were returned.  If the length of the array returned is 0 you can just append -001 to the Title of the item since its the first approved. If its greater than zero you need to get the number on the end of the first item and increment it by one.



So in the Yes side (>0) I used two compose statements to do the calculations. The first gets the first entry, gets the number off the end and increments it by one using this formula


This gets the title of the first item, splits it on the '-', gets the last entry from the split, converts it to an integer, and adds 1.

Now we take that number and add it to the end of the Item Title that we want to update.  We use formatNumber to make sure its in -001 format.


Then we just use the output of that Compose as the updated Title for the item.


And here is my result: 



Best regards
