How to prevent users from loading dynamic member to the system when using data load rule

Hello everyone,

We have a data load rule to import data from a file to PBCS.

In this file, we have the Account parent level, which is set up as a dynamic member in the system.

However, when we run the data load rule, the system does not show any error to warn us that the file has a dynamic member.

When I check the log file, it only shows that there were some rows rejected.

My question is:

Do I need to set up anything to ensure that the system will inform us when our file has a dynamic member?
