If you create a custom function to export data in XML format based on codeuntis 1605 or 1610 and try using the same configuration in SaaS you are not able to. If you try debuging the code there are lines pointing to Scope(OnPrem) i understand it is not usable in SaaS environments however the code units mentioned above are configured the same way and are working.
