Create gl_interface record during AR transactions accounting

Hello,

I want to know what is the best way to insert some records in GL_INTERFACE when accounting some AR transactions ? AR transactions and new lines in GL interface are not in the same book. I think it's not possible to do this with SLA set up so I want to custom a package.

I know that I can use the package GL_IMPORT_HOOK_PKG for customizations.

Is there other package that I can modify in accounting process ?

Thanks,

Antoine
