Got ORA-06550 and PLS-00306 when running a package in Oracle concurrent process

Hello there,

We are on Oracle DB 19C and Oracle 12.2.4. TOAD version 15.1.

I created a very simple package for AP interface in TOAD and I could compile it and execute it without any problem. I also saw the lines in AP interface tables, created by executing this package in TOAD and I could create AP invoices from the lines by running AP invoice import.

However, when I created a concurrent process in Oracle Apps by using this package, I got ORA-06550 and PLS-00306 errors when I ran it in Oracle. This is the first time for me to run into this error and I have been using this way to create the concurrent processes many times.
