Hello Pedro,

You can add a few equal phone numbers as the communication options. All you need is to choose the different types for them:

Hi Anhelina,

Thank you for the response.

The idea here is to use the same type. For example, we need to create multiple duplicated instances for "Mobile Phone", because later on we will be using these records for our business logic. The number might be the same, but we have other attributes that have unique keys. We want to change this rule so it can be applied to those attributes.

Best Regards,

Pedro Pinheiro

Give your code with a call setValidationConfig

But I think it's better case override  BaseCommunicationDetail and overriding addItem() 

And add your validator by analogy as there is added duplicate checking and number checking:

this.addColumnValidator("Number", newItem.validateField, newItem);
this.addColumnValidator("Number", newItem.checkCommunicationDuplicates, newItem);

Thanks Grigoriy, I got an idea.
