Pullout Parameters control the validation of operator vehicle logon. myAvail always validates both the Operator ID and the vehicle ID. However, there are additional pullout parameters that can ensure the operator is logging on to the correct run on the correct vehicle. The following describes those parameters and the grid defines how they interact:

Enable Operator Validation - True means Operator ID must match between Log on and Pullout rows.
Enable Operator Logon with No Assignment - True Overrides Enable Operator Validation if the operator ID in the Pullout row is NULL.
- If Enable Operator Validation is false, then this parameter is ignored.
Enable Vehicle Validation - True means Vehicle ID must match between Log on and Pullout rows.
Enable Vehicle Logon with No Assignment - True Overrides Enable Vehicle Validation if the operator ID in the Pullout row is NULL.
- If Enable Vehicle Validation is false, then this parameter is ignored.

Possible Parameter Combinations

Case #	Operator Validation	Vehicle Validation	Operator Update with No Assignment	Vehicle Update with No Assignment	Result
Case 1	FALSE	FALSE	FALSE	FALSE	The pullout row is selected by Block and Run and it takes the first pullout row it finds that is not already logged in. All valid runs have a pullout row.
Case 2	FALSE	FALSE	FALSE	TRUE	Enable Vehicle Logon with No Assignment ignored. Same as Case 1.
Case 3	FALSE	FALSE	TRUE	FALSE	Enable Operator Logon with No Assignment ignored. Same as Case 1.
Case 4	FALSE	FALSE	TRUE	TRUE	Enable Operator Logon with No Assignment and Enable Vehicle Logon With No Assignment ignored. Same as Case 1.
Case 5	FALSE	TRUE	FALSE	FALSE	The Vehicle ID of the logon must match a pullout row to be validated. The Operator ID is not checked.
Case 6	FALSE	TRUE	FALSE	TRUE	The Vehicle ID of the logon must match a pullout row or be NULL to be updated. The Operator ID is not checked.
Case 7	FALSE	TRUE	TRUE	FALSE	Enable Operator Logon with No Assignment ignored. Same as Case 5.
Case 8	FALSE	TRUE	TRUE	TRUE	Enable Operator Logon with No Assignment ignored. Same as Case 6.
Case 9	TRUE	FALSE	FALSE	FALSE	The Operator ID of the logon must match a pullout row to be validated. The vehicle ID is not checked.
Case 10	TRUE	FALSE	FALSE	TRUE	Enable Vehicle Logon with No Assignment ignored. Same as Case 9.
Case 11	TRUE	FALSE	TRUE	FALSE	The Operator ID of the logon must match a pullout row or be NULL to be updated. The vehicle ID is not checked.
Case 12	TRUE	FALSE	TRUE	TRUE	Enable Vehicle Logon with No Assignment ignored. Same as Case 11.
Case 13	TRUE	TRUE	FALSE	FALSE	The Operator ID and Vehicle ID of the logon must match a pullout row to be validated.
Case 14	TRUE	TRUE	FALSE	TRUE	The logon Operator ID must match a pullout row and Vehicle ID of the logon must match the pullout row or be NULL to validate.
Case 15	TRUE	TRUE	TRUE	FALSE	The Operator ID of the logon must match a pullout row or be NULL and the logon Vehicle ID must match the pullout row to be updated.
Case 16	TRUE	TRUE	TRUE	TRUE	The Operator ID and Vehicle ID of the logon must match a pullout row or be NULL to be validated.
