I have the table tbl_risco and tbl_tipo_de_risco in the Dataverse and they have a Many-To-Many relationship.

I'm on the Risk screen (tbl_risco) and I need to bring in a Choice function what is in the tbl_tipo_de_risco .

The card is as follows:

The field looks like this:

I've already tried to put some paths in the Choice field for testing and nothing worked, it gives the following message:

Translation from pt-br to en: "The specified column is read-only and cannot be modified"In the images above I left with the initial configuration for new tests.

Hi @Akash17

This seems to be the path I have to follow, but it's still complicated.

In the documentation it says:

"These functions never create or delete a record. They only link or unlink two records that already exist."

On the tbl_risco screen I want to be able to select what is in a Choice that would come from tbl_tipo_de_risco and then click on the Save button. Is the documentation already stating that this is not possible or did I understand it wrong?
