Record Reservation

You can update and process operation and vessel records using multiple programs in the JD Edwards EnterpriseOne Blend Management system. To avoid simultaneous processing of the same vessel or operation, the system reserves (locks) records for processing by any other program. When you access and edit an operation record, the system reserves the record for that program. Additionally, the system reserves all vessels that are attached to the operation, as well as its downstream operations. These programs use record reservation:

• Operation Header (P31B69)

• Create/Edit Operation Detail (P31B87)

• Speed Operation Update (P31B96)

• Inventory by Vessel View (P31B81), if you create operations from the vessel list

• Search for Operations (P31B94)

• Search for Work Orders (P31B95)

• Speed Advanced Comment (P31B317B)

• Speed Results Entry - Blend Management (P31B98)

• Enter Global Admin Operations (R31B88)

Record reservation is also used for interoperability operations.

When another user attempts to access a reserved operation or vessel, the system issues an error message indicating that the operation or vessel is reserved. Users must wait until the system releases the records; however, any user can view the records.

If you reschedule operations by changing the planned date of an operation, you change the dependency chain. That means that revising an upstream operation may now affect different downstream operations and vessels. If a vessel in a downstream operation is already reserved from a different application, the system cannot process the record reservation and returns an error message.
