Hi Arnaud
Thanks for the response. I tried your suggestion but the issue still exists.
What confuses me is
1. the projects and transactions that were recently created [in the last 5-6 Months] are working fine and are able to call other transactions.
2. If I create new transactions and call them , they are also executing fine.
3. Only the older ones are failing. I even tried changing the names and executing that also failed.
Not sure if there is a naming compatibility issue between 12.0 and 12.2 or some special characters that were accepeted in 12.0 and not supported in 12.2. ButI have noit read about that that anwhere.
