1. Storage type for inbound attachments is always first searched for in the company-dependent Inbound configuration - based on company ID and ERP object ID and/or file type.
2. If the attachment’s company, object type and file type won’t match any pattern found in the configuration, customizing will be searched for in the default Inbound configuration - based on ERP object ID and/or file type.
3. If no relevant entry is found, it will be searched for in the company-dependent General attachment configuration - based on company ID.
4. If not found, a storage type would be taken from the default General attachment configuration.
