Creatio 8.2.3.1351 – How to Configure Primary Key for Custom Entity

Hello everyone,

I am working with Creatio 8.2.3.1351 and facing an issue with configuring the primary key in a custom entity.

Details:

• Package: UsrTest_App
• Environment: Cloud demo
• Issue: By default, Creatio always uses the system “Id” (GUID) column as the primary key. I tried to set another column as the PK, but it did not work.

What I tried:

1. Created a custom entity in Configuration.
2. Added a new column, set it as unique and required.
3. Tried to configure it as primary key in entity settings.
4. Still, Creatio uses the default “Id” column.

My questions:

1. Is it possible to change the primary key of a custom entity in Creatio 8.2.3.1351?
2. If not, what is the recommended approach for implementing a custom unique identifier?

I have screenshots of the entity model and error message if needed.

Thanks in advance for your help!
