See Run an ObjectScript Routine from Embedded Python^2024.1

Example:

USER>d $system.Python.Shell()

>>> iris.routine("fnString^IRISPython",14)
'Hello 14'

Hello @Vitaliy Serdtsev,

I executed the routine invocation commands in native python script.

Starting from 2024.1 IRIS Native disallows routine invocations. Please use class methods instead.

For reference, these changes can be identified as DP-422635 and DP-424156.

Thank you @Eduard Lebedyuk. Could you please paste the link of DP-422635 and DP-424156.that would be helpful.

I join the question @Ashok Kumar.

I did not find DP-422635 and DP-424156 among the published ones:

In addition, there are no warnings in the documentation that these methods are deprecated and no longer work: Calling Functions and Procedures from Python

I believe what you're looking at is the new, more fine-grained set of %Native_* resources you need to use native functions. Look for DP-423341 in the upgrade guide. It seems we failed to describe this requirement in the Native API documentation (or at least I didn't find it where I expected it), so we'll get that addressed.

I'd also recommend defaulting to the new, dynamic upgrade guide that makes it easier to filter on particular types of issues. This is now replacing the old, static pages that were more reliant on / vulnerable to manual curation. In fact you'll no longer find those static pages from the menu in the 2025.1 doc.
