Fnd_request.submit_request with multiple language request

Question

Hey all,
Looking for some advice on submitting multiple requests via plsql fnd_request.submit_request, or something along those lines.
Long story short, I would like to submit the concurrent request Invoice Print New Invoices from a plsql scirpt "code unit".
When running that request from the applications, it first runs the parent request "Multiple Language" which in turn spawns the child request "Invoice Print New Invoices", which is the request thas uses the parameters entered in the parameters form interface.
_Any suggestions on how to mimic this functionality via a plsql scirpt "code unit"?_
Thanks,
Hayden

There is no such thing as PL/SQL scripts.. as PL/SQL is not a scripting language. It is formal structured procedural language with object orientation features.
It's a mistake to think of any structured procedural language as a mere scripting language.
Your requirement is unclear. What do you mean with "+in turn spawns the child request+"?
PL/SQL "+code units+" consists of packages, procedures and functions - or can be an anonymous block submitted from a client (this is typically used to call packages/functions/procedures).
It's a standard feature of structured procedural languages to have code units and have these calling one another - e.g. package calling a procedure which calls a function which calls a procedure.
If you are inferring some form of multi-processing or threading, then there are a number of ways this can be implemented in PL/SQL. By default PL/SQL does not support threads given the process architecture of process that executes the PL run-time engine. However, PL code can make use of Oracle's Parallel Query facility by using parallelised pipelined table functions. PL code can use something similar to the Unix "+fork()+"'ing model by starting "child processes" as DBMS_JOB processes. IPC (Inter Process Communication) between PL processes can be done using Oracle Messaging. Semaphores can be implemented via the DBMS_LOCK API. Etc.
There's a host of features that PL provide.. (including transparent integration with the SQL engine). Scripting language? Don't think so. Unless you decide to treat it as one in which case you are not leveraging any of the many powerful and flexible features that PL/SQL provides.
