Two-Way Validation

When a new operation is added to an existing harvest, the system performs a two-way validation. The first validation compares the new operation to existing operations. The system verifies, for each withholding type that has a check in the validation check box on the new operation, that the operation dates do not overlap with the withholding periods for the existing operations.

The second validation compares existing operations to the new operation. The system verifies, for each withholding type that has a check in the validation check box for the existing operation, that the operation dates do not overlap with the holding periods for the new operations.

This diagram shows three existing operations, and the validation that occurs based on the validation check box being selected and the withholding days being defined in a new operation:

In the above example, a new operation is added that has the validation check box selected for prior and subsequent activities. The system validates against the existing operation, Operation 2, because it has withholding days entered for subsequent activities. The system also validates against existing operations that have prior withholding days entered. In this example, none of the operations have prior withholding days.

Next, the system validates the existing operations that have any validation check boxes selected. For Operation 1, the reentry validation check box is selected. The system validates against the new operation because the reentry withholding days is set to two.
