Hi @Kamil Janeczek,
I have some basic questions.
1. In a constellation, is it always recommended to create a new data model either in the implementation layer or organizational layer (e.g., Contact), or can we reuse an existing data model (e.g., PegaDATA-Contact) through inheritance? I haven't found any documentation references on this. What is the recommended approach for a greenfield application?
2. Also, should we build a new greenfield application on top of the Pega Common Data Model application, or as a standalone? What is suggested?
Thank you.

How to Add Read-Only Text to the UI or View in Constellation Without a Data Model
In traditional UI, we add a paragraph to the section. Similarly How can we achieve this in Constellation without using a data model?

@Arunkum@r Hi Arunkumar,
In Constellation I see Form views allow to override case instructions, likewise we used paragraph rules in UI-Kit to add additional information to a collect information step.
Field groups also allow this, so you might add your text to either of those. So, in a nutshell you can combine Form views (like to add top instructions) and then field groups to add more focused instructions.
Hope this helps.

Hi @Kamil Janeczek , Greetings. Hope you are well! I have a List being displayed with a single select, however i see the radio button selection is greyed out, i even tried with latest Search and Select but still the button is greyed out. I am on Pega 24.1.1. Please see below screenshots for reference.
Any suggestions?
Regards,
Bharat

@KOMARINA Hi, which button is greyed out, the radio buttons? It is not evident from the screenshot. Can you attach configuration of this field?

@Kamil JaneczekHi Kamil, Greetings. yes, the radio buttons are greyed out, last screen shot is of the view which has List and mode single-select.

@Kamil Janeczek No, Data Page just gets a response from a Connector and forms the list, not custom configuration to make it readonly

@KOMARINA The configuration of the Datapage can have something to do with this, Check if Allow Querying checkbox is checked in the Datapage.

@Kamil Janeczek hi Kamil, how to configure 'Search and Select" feature in Landing Page? Use case is to build custom search capability to query data from external system or simplified view.

@VenkatVVSearch and select pattern is available only for Data Reference field (so inside Case). For landing pages you can use promoted filters that are available on:
- List Views
- Insights

@Kamil Janeczek Hi Kamil - these are great standalone resources. The excellent Constellation Adoption mission (which I know you were a fundamental contributor to) is a more structured way to learn Constellation. It would be good for this audience to understand whether these articles are in addition to, fully covered or partly covered by the mission. I'll take another look at the SweetLife sample application and see if I can map these 101 articles back to specific parts of the learning journey provided by the mission.

@NiallThanks Niall. Those materials are meant to extend what we covered in Constellation Adoption mission. This is in response to many voice that SAs/LSAs need more practical and hands on experience.
I would advise everyone to go through Constellation Adoption mission and then search for additional guidance in Constellation 101 series.

@Kamil Janeczek I would like to ask one question regarding Converting Sales automation to constellation. Can you please guide me on this and one important question I have is, for sales automation migration from UI kit to Constellation, do we need to build the application from scratch in constellation like how we are doing for Smart Investigation or we just convert UI kit sales automation through pega modernization assistant. Please guide me on this. Thank you.

@Kamil Janeczek I would like to clarify one issue I am getting on one of our Constellation application. We have an insight on one of our data type and it's showing all the values correctly. However, while applying filter on one of our fields(Type-Text), it's showing error. During inspection, I found the payload which shows that it has error but I am not able to find what's wrong with that filter field. I have tried applying filter on some other text fields available on that Insight, all are working fine. I have attached the error details and also JSON Payload for the query.

@Kamil Janeczek Hi Kamil, this issue is resolved as we have modified the column type for the specific field. So, few months back this field was newly created with a type change. So it created a type mismatch between DB column type and the Pega property type. We have modified the column type to Varchar with the help of PegaCloud team and it's working fine now. Thanks a lot for responding.
