Resolving *SRVPGM for ext stored proc

I have an external stored procedure around a RPGLE service program. The
stored proc does not specify a library for the service program. For some
reason, source control promotes the stored proc to 2 libraries. The
service program only exists in 1 of those libraries.

The .NET caller uses System naming. The library list contains both of the
libraries where the stored proc resides. It finds and executes the stored
proc in the highest library in the *LIBL. Then it assumes the service
program is in the same library, rather than using *LIBL. Since the
service program doesn't exist in that library, it fails (the service
program is in the other library).

How can I get it to use *LIBL to resolve the service program?


Thanks
