Data loading activity in v8


Hi Adobe Team,
I am using the Data Loading activity in Adobe Campaign Classic v8, which includes a column for studentid. Upon analyzing the data, I noticed that the studentid column contains blank values.
I have configured the following settings:
Allow Null: Set to "Always populated."
Error Processing: Set to "Ignore the value."
However, I observed that the entire row is being rejected instead of ignoring the blank value and processing the other column values. I am unable to understand how the error processing works, despite reviewing the Adobe documentation.
Could you please provide clarification on the following error processing options and how they function?
1. Ignore the value
2. Reject the line
3. Use a default value in case of error
4. Use a default value in case the value is not remapped
5. Reject the line when there is no remapping value
Thank you for your assistance.
