Appian Certified Analyst (ACD201) — Question 1

You run a report on different employee transactions by using a View.
You encounter the following error: "a!queryEntity: An error occurred while retrieving the data."
What is the most likely root cause of this error?

Answer options

• A. The view doesn't have a column mapped as a primary key in its corresponding CDT.
• B. The view contains a large number of rows, requiring more time to fetch the data.
• C. The rule contains a missing syntax.

Correct answer: A

Explanation

The correct answer is A because a primary key is essential for uniquely identifying records in a View, and without it, data retrieval will fail. Option B is incorrect since although a large number of rows can slow down performance, it does not typically cause an error message like the one described. Option C is also incorrect because a missing syntax would result in a different type of error than the one mentioned.
