Issue 1: You are not able to save the model in AAM Customer UI even though the limit of models has not been reached. Also, while saving the model, you are not getting any errors. When you click on the Save button, nothing happens.
Issue 2: You are unable to deactivate or delete the model in the AAM Customer UI. While deactivating or deleting, you are getting the error Access to this trait has been revoked. Please find the below screenshot.
Solution 1: Check all the traits used by the segments in the model. There might be a possibility that you would find a trait that is taken from Audience Marketplace, but a subscription for modeling is not enabled for the traits which you are using in your model. In this case, you would not be able to save the model. To save the model, remove all those traits or enable the subscription for modeling for these traits. Note that in case you want to enable the subscription for modeling, you might require to pay extra charges for that.
Solution 2: One of the possible ways to overcome this issue:
Check all the traits used by the segments in the model which you want to deactivate or delete. There might be a possibility that you would find a trait that is not available. Check the below screenshot:
Remove all those traits which are not available, then try to deactivate or delete the model. Now, you might be able to successfully deactivate or delete the model.
Note: When getting an error message in the UI, you may want to enable the Developer Tools when using Chrome and select the network tab, then try and replicate the above action again. The developer tools are likely to present more details, including the dependencies preventing you from completing your actions. This may help you understand the reason behind a UI error.
