-
Whether the form is empty or populated, performing a Drill screen rule call on any eligible field causes all preceding keynbrs to be included in the call.
-
If preceding fields are empty, the keynbrs corresponding to those fields are included in the call as parameters with no values.
-
If preceding fields are populated, the keynbrs corresponding to those fields are included in the call as parameters. The values of each of the keynbr parameters included in the call is the value of the field to which each keynbr belongs.
-
If following fields are empty, the keynbrs corresponding to those fields are not included in the call.
-
If following fields are populated, the keynbrs corresponding to those fields are included in the call as parameters. The value of each of the keynbr parameters included in the call is the value of the field to which each keynbr belongs.
