Problem: transactionid value -1

Hello

I'm using MII 12.2(.5)

In a transaction I use the transactionidstandard function for a variable assignement.

If I run the transaction using manual commmand (CTRL+F5) it works fine.

If I run the transaction using a scheduled job (System management->Scheduler), it returns always -1 value. The same issue if I run the transaction using both webservice and HTTP call.

The user used in all the calls is the same.

Do you have any idea about the issue?

Thank you a lot
