Creating a unique ID building off of the response ID.

Posted on by SLBMetrology

I'm trying to create a unique ID easily using the response ID. I want the numbers to go up by 1 each time a new entry is added to my List. I would like it in the format of 2021-1011, 2021-1012, etc.

The way I have it set up now gives me that except when it hits 2021-1099 the next one will jump to 2021-10100 instead of 2021-1100 like I would prefer it to do.

Is there an easy way to make that happen by adding a simple formula within this cell?? Below is the picture of the flow I have started.

Thank you in advance for your help.

Re: Creating a unique ID building off of the response ID.

@SLBMetrology I think you are using SharePoint list, so I would advise you to have a list which holds your counter value.
My list

My flow
When your flow gets trigger, first get the counter value and use counter as required
Increment the counter and update the counter value

I ran the flow, counter value after first run and keeps on increasing
add(int(outputs('Get_item')?['body/Title']),1) /* adds 1 to string value from Get list item action */
Keeping a track of the count and having the logic to get the current count and then update it in the flow is not the best approach.

Hope my idea helps.

Re: Creating a unique ID building off of the response ID.

Hello @SLBMetrology ,

I'd build the unique ID before the 'Create item' action in a variable and then use the variable instead.

Intialize a string variable

Add a condition to check if the 'Response Id' is less than 100

If it's less than 100, store 10[Response Id] into the variable

If it's more than 100, store 1[Response Id] into the variable

Use the variable in the 'Create item' action: formatDateTime(...)-[variable]

Re: Creating a unique ID building off of the response ID.

@tom_riha this is good solution as long as the response ID doesn't exceed 999.

And we would have to keep adding the conditions every time the response changes from 999 to 1000 and then again 9999 to 10000 and so on and handling this would bring a switch case or something which will check if response ID is less than 100 or greater than 100 but less then 1000 and so so, it will keep adding it up making it more and more complex for no reason.
