Error Log?

Hi Support,

Suppose if a scheduler runs and tried to pull the data from different server but due to some issue or incompatibility data in those CSV/Spreadsheets, Some Rows may not be inserted or based on the configuration the NULL value will be set to those respective columns.

Do we have any error log system where i can identify these rows and columns which are error prone and not imported successfully? Do we have this provision if so how do i access it ?

And do we have rollback and retry options available for the data import from external servers?

Looking forward to hear from you. Appreciate your help.
