Just to add one more thing. In case you can choose from a large amount of items, it is not a good idea to load all into memory and pass them into the suggest function. In this case you should implement a dynamic query from DB inside the suggest function.

That did the trick! Thank you! With a little tweak it worked great. Had to add touniformstring() in the wherecontains() but other than that, it is working as expected.

Thanks Peter, st07, and sandeepd. :-)

Here's the final code:

a!pickerFieldCustom(
    label: "Select Faculty Advisor",
    labelPosition: "ABOVE",
    instructions: "Search for Faculty Advisor by name or employee Id",
    placeholder: "Enter names here",
    maxSelections: 1,
    suggestFunction: rule!ADA_LookupAdvisorsFilter(
      filter: _,
      labels: local!data.name,
      identifiers: local!data.emplid
    ),
    selectedLabels: a!forEach(
      items: local!selection,
        expression:
      index(local!data.name, 
        wherecontains(
          fv!item,
          touniformstring(local!data.emplid)
        )
      )
    ),
    saveInto: local!selection,
    value: local!selection
)

Hey , please add .data at the end of your query entity (line 25) ADA_lookupadvisors so that it gives you data in dictionary type format ( excluding startIndex, totalcount , batchsize etc) . Alternatively , In the interface, you can define the local variable like this : local!data : rule! ADA_lookupadvisors().data. You can try any of the above two methods. That should work.

Hi Peter,

First off, love you training videos. They are very helpful. Keep up the good work!

I think I'm close but seems that I'm not quite there yet. Seems to be a problem in the selectedLabels, specifically the forEach expression. I'll attach some screenshots. Maybe you guys can spot something I'm overlooking.

The easiest way to set this up with data from a database is to create a query that returns all of the data from your CDT. Then, just replace the "labels" list with your description and the "abbreviations" list with your id. Keep in mind you might need to also change some of the data types for your supporting rule (for instance, the "identifiers" rule input should be an integer instead of text). If you do this correctly, your final expression could look something like this:

a!localVariables(
  local!selection,
  local!data: rule!GetAllReferenceData(),
  a!pickerFieldCustom(
    label: "Label",
    instructions: "Value saved: " & local!selection,
    maxSelections: 1,
    suggestFunction: rule!ucArrayPickerFilter(
      filter:_ , 
      labels: local!data.desc, 
      identifiers: local!data.id
    ),
    selectedLabels: a!forEach(
      items: local!selection,
      expression: index(local!data.desc, wherecontains(fv!item, local!data.id))
    ),
    value: local!selection,
    saveInto: local!selection
  )
)

htmoore,

Below code may help you.

a!pickerFieldCustom(
label: "Select Data"
placeholder: "Type Min 3 characters",
labelPosition: "JUSTIFIED",
required: true(),
maxselections: 1,
suggestFunction: ##Write Expression rule to get ID & Desc Data from Data base# Use index function to get data index. Also, in Query entity Filter use operator: "includes" ##
selectedLabels: index(
rule!getDetailsByID(
Id_int: local!selectedId
),
"Desc",
null
), #Here get details from table by passing Id #
value: local!selectedId,
saveInto: {
local!selectedId,
)

Thanks,
Sandeep
