BC returns error when trying to create a subscription to an endpoint based on table "BOM Component"

Hi guys,

I have created a custom API based on "BOM Component" table and when I try to create a webhook (subscription) within an external service I receive the following error:

This is the definition of the Api page:

I have other API Pages published in the same enviroment, based on other tables a everithing work ok, except this one.

Any ideas?

    Not sure, but here you have DataAccessIntent = ReadOnly. Never tested if subscriptions work on the reas-only replica. Can you test without this?

    Thanks for your reply Stefano,

    I have performed the test that you have told me. I have removed the DataAccesIntent = ReadOnly property and it keeps returning the same error.

    On the other hand, I confirm that the subscription works with other models and with the DataAccesIntent = ReadOnly property.

    I have done the test on the Production version and a clean Sandbox in the latest version (17.5.22499.22680).

    Hi again, 

    I've been talking to Microsoft Support and It seems that you can't create API subscription with a composite primary key. 
    In this case, It was using the primary key of the "BOM Component" table, which is: "Parent Item No.", "Line No.".

The solution was simple, just add the SystemId field to the page and set it as OdataKeyFields.

    True. Missed that in your code, sorry.
