While Stephen's try isn't bad, official SAP terminology is "cross-*" instead of "inter*":

anwendungsübergreifend = cross-application
auftragsübergreifend = cross-order
belegübergreifend = cross-document
bereichsübergreifend = cross-functional
buchungskreisübergreifend = cross-company code

Also, the SAP Style Guide suggests moving the adjective "standard" to the front of the phrase whenever the talk is of "{some adjective} Standard{somethings}.

All together, it makes for "standard cross-module processes"
