I have a request to generate a tracker number when a new item is created to a list based on the below logic:

  1. The number format is "TN" + CurrentDate(ddMonYY format) + Counter. eg: TN18Oct2101
  2. The counter increments for that day for all tasks created. The counter will be reset on everyday. For eg: TN18Oct2101, TN18Oct2102,...Then TN19Oct2101

Can this be achieved through a calculated column?

Thanks Venkat

    This is achievable using calculated column only if you enter the "Counter" manually from list forms. Oct 19, 2021 at 4:25
  • This isn't possible from a calculated column as you cannot reference other rows (to know what the counter value should be). Best bet would be to solve this using Power Automate with a flow that runs on item creation and first does a query of entries with a Created date of today and uses the count of results to determine the counter value. However, depending on how fast items are being added there is the potential for a concurrency issue that may need to be accounted for. Oct 19, 2021 at 13:39

Please following steps:

1.Create a Single line of text column named "Counter"

enter image description here

2.Create the first Calculated column named "Current Date"

Formula:

=TEXT(TODAY(),"ddmmmyyyy")

enter image description here

3.Create the second Calculated column named "Tracker number"

Formula:

=CONCATENATE("TN",[Current Date],[Counter])

enter image description here

enter image description here

4.If you don’t want to show "Current Date" column, you can choose to hide it

  • Thanks. Can the counter column be a calculated column and it auto increments by itself on every record got added? Also the counter needs to be reset and starts from "1" on every day like i mentioned in my question 2.

  • Hi user2459457. The calculated column does not auto increments by itself, it is combined according to the value in the [Counter]. Note: The value in [Counter] is manually entered by me. Oct 20, 2021 at 8:38
