Balance Explanation Loads incremental or get overwritten everytime data is loaded ?

Summary

Balance Explaination Loads

Content

We are planning to use the  importPreMappedTransactions  epmautomate command to load balance explanations. 

My question is, do we run the extract every day and just load new incremental data ? Or do we load full months data and everytime it gets loaded it will replace the last load?

 

Thanks,
