Hi, kindly seek your help.

In SA mission exercise

https://academy.pega.com/mission/system-architect/v4/exercise/in/29826

After I complete US-2006, everything is normal, customer info can be stored into Data Object as new record when Enroll is selected. (To simplify , in the Data transform "SaveNewCustomer",  only 3 fields are copied: FirstName, Username and Password, so in saved record only 3 fields have values)

However, as I tried, if I delete the read-only view "Collect customer information" in the "Verify new customer", as below red underlined

and then run the case again with Enroll selected, I found the record store in data object have all fields are null. After I add back the read-only field, then it turns to normal.

The CURRENT status of my exercise is the the read only view is deleted, in below picture, 1st record (empty) is added in current status, 2nd record (normal) was added before I delete the read only view.

Pls kindly help to check what caused this problem. Thanks.

2nd question is that (to see whether you have quick idea), some time before, when I just completed US-2002 in this exercise before continue remain tasks,  I found the customer info saved into Data Object have ALL fields have values as what I input, even  the Data transform "SaveNewCustomer" only copy 3 fields, it proves that, at that time, the saved record does not rely on the data transform to copy fields values. But later, now, when I complete US-2006, I found the saved record only have 3 fields have values, so it should the data transform take effect. Wonder what cause this, thanks.
