Do you receive service for essential machinery or equipment from a number of service providers? If so, you can manage and document it using the service module in SAP Business One.
The service module is enhanced to support the creation of service calls for vendors, assignment of equipment cards to vendors and allocate service contracts to vendors.
The service module reports are also adjusted to include data related to vendors and is available since SAP Business One 9.3, version for SAP HANA and SAP Business One 9.3.
