Hi all - I'm having an issue uploading "historic" trial balances. Does anyone have experience with doing any work on uploading "historic" trial balances?

I tried finding a guide we used to have but could not. This link is fairly easy to follow http://blog.prolecto.com/2015/06/14/how-to-upload-a-netsuite-trial-balance/ The main part is to post balances as of the last day of the month and reverse for 1st day of the following month

Thanks Alex. My issue is mainly with retained earnings line getting double counted as I'm doing years of imports.
