Multi Drop Down Validation

Question

Hi Friends, 
 Please look at the screenshot. There is a two rows. In that two rows should validate when the two rows are equal. So what i am planning in the "Department" section. When i used "Corporate" in the dropdown then it should not come in the second row. Please share your thoughts.

a!localVariables(
 local!savedValueIndex,
 local!firstDropdownSavedValue,
 local!secondDropdownSavedValue,
 local!choiceLabels1: {
 "Corporate",
 "Engineer",
 },
 local!choiceValues1: { 1, 2 },
 local!choiceLabels2: {
 "Corporate",
 "Engineer",
 },
 local!choiceValues2: { 1, 2},
 {
 a!dropdownField(
 label: "Dropdown",
 labelPosition: "ABOVE",
 placeholder: "--- Select a Value ---",
 choiceLabels: local!choiceLabels1,
 choiceValues: local!choiceValues1,
 value: local!firstDropdownSavedValue,
 saveInto: {
 a!save(local!savedValueIndex, index(local!choiceValues1, save!value, null)),
 a!save(local!firstDropdownSavedValue, save!value)
 },
 searchDisplay: "AUTO",
 validations: {}
 ),
 a!dropdownField(
 label: "Dropdown",
 labelPosition: "ABOVE",
 placeholder: "--- Select a Value ---",
 choiceLabels: if(
 a!isNullOrEmpty(local!savedValueIndex),
 local!choiceLabels2,
 remove(local!choiceLabels2, local!savedValueIndex)
 ),
 choiceValues: if(
 a!isNullOrEmpty(local!savedValueIndex),
 local!choiceValues2,
 remove(local!choiceValues2, local!savedValueIndex)
 ),
 saveInto: {
 a!save(local!secondDropdownSavedValue, save!value)
 },
 searchDisplay: "AUTO",
 validations: {},
 value: local!secondDropdownSavedValue
 )
 }
) 
 
 Please refer the code to figure out the logic to conditionally manage the choice labels and values.

Hi there, 
 You can add a validation when a single value has been selected more than once. You can use wherecontains function and use it on the CDT/Dict field. If it returns more than one item, then you could show a validation.
