Changing Contract Line Items
Service coverage has important implications throughout the system, especially in call-tracking functions. When a call exists that references a contract, the system restricts changes to that line.
Example: Item 116, serial 12A is covered on a contract. A call is taken for this item. The contract coverage found by the system determines call defaults such as response time and next event date and time. An engineer responds to the call, and reports are opened in Call Activity Recording. Based on the contract limits, the system calculates coverage and generates an invoice.
If the system let you change the serial number on the line in Contract Maintenance, the coverage previously calculated would be invalid.
When a contract line is referenced by a call, you cannot:
• Change the line’s service type, item number, serial number, and reference number.
• Delete the line.
• Move the line start and end dates within the range defined by the earliest and latest call open dates referencing the call.
• Add new limits when open reports exist.
Before you can update a contract line referenced on a call, the calls referencing it must be closed and moved to history.
