Creating and Updating Service Calls 
You can create an initial service call or update a service call to record tasks, meetings, notes, or expenses related to the call, or to enter a solution to the service problem.
Note
You can also use the Business Partner Master Data window to display the service calls recorded for a customer. Find the relevant customer and choose Related Service Calls.
Typically a customer who contacts you for service already has a service contract with your company for an item or group of items, or the item is covered by a warranty. Additionally, you have created customer equipment cards for the items for which the customer is requesting service. However, you can create a service call without a contract or warranty, although you will get a warning message when you save the service call.
You can create a service call only for serial number items with an Active or Loaned status. You get an error message for serial number items with one of the following statuses:
Returned
Terminated
In repair lab
