Shubham Aware Somehow we have encountered this issue for July too earlier but in 2025, facing issue with September. I am sure Appian should have some resolution going forward to fix it from root.

I will try the recommendations you have shared. Thanks for keeping an eye on this.

Got you! This issue is because of user locale.

User Level: Change user profile locale from en_GB (UK) to en_US (US) => affects only that user
Admin Level: Go to Admin Console -> Internationalization -> Change Primary Locale to en_US => applies to all users in the environment.

This locale problem is only for September month recommend you to make changes to code instead of environment level.
Below working example for all months

a!localVariables(
  local!date:"09/11/2025",
  local!formattedDate: text(local!date, "dd-MMM-yyyy"),
  if(
    isnull(local!date),
    null,
    substitute(
      local!formattedDate,
      "Sept",
      "Sep"
    )
  )
)

Can you check if under Settings->General you have locale set as English(United Kingdom). Looks like the Internationalisations settings are at play here causing this behaviour. I have it as United States and it returns output as 'Sep'

If for reasons, you cannot update the Locale to US then you can try and handle the September month like below. Give it a try!

if(
  month(ri!date) = 9,
  substitute(
    text(ri!date, "dd-mm-yyyy"),
    "-09-",
    "-Sep-"
  ),
  text(ri!date, "dd-mmm-yyyy")
)

You can simply use text to get the desired output, why make it complex with left(). For every date this will work for you by passing the expected output format in text().

text(ri!date,"dd-mmm-yyyy")

Could you try this once
Let me know if that works for you.

text(
  index(todate("09/09/2025", "MM/dd/yyyy"), 1),
  "dd-MMM-yyyy"
)

I am expecting incoming date in the format "09/09/2025" and output should be in dd-mmm-yyyy. For rest of the months the existing code is working fine. However, returning September as Sept.

Input - "09/09/2025"

Output - 09-Sep-2025

May i know what input and output you are expecting to help you better?

This is still not working. As the left function needs the number of characters to be extracted from the text which is still missing from the code. It is not giving any result.

Remove the 3 from the text() function. The text() function only needs:
The date value (ri!date)
The format string ("mmm")

if(
 rule!APN_isBlank(singlePV: ri!date),
  "",
  left(text(ri!date, "mmm"), ri!format)
)

The left() function with ri!format will handle truncating the month name to the desired length.

Harsha Sharma — Tue, 09 Sep 2025 10:08:06 GMT

if(
  rule!APN_isBlank(singlePV: ri!date),
  "",
  /*left(text(ri!date, "mmm",3), ri!format))*/
  left(text(ri!date,"mmm"), 3) 
)

text() needs two parameters (value, format), left() needs two parameters (text, num of chars). Your text() has 3 parameters which might be causing this. Try and work with the above code to resolve the issue.

When inserting code using this is recommended Insert->Code
