We have a custom import suitelet (and scheduled search) that is used to update custom transaction line fields on journals and expense reports after the monthly close. A user imports a CSV file, the scripts load the record, and then the custom fields are updated and the record is saved. This has worked mostly without error for nearly 2 years. Starting a few weeks ago, we are starting to get errors left and right. It seems line numbers are off (they are downloaded from a saved search of the data) for some transactions, we're getting "cannot make G/L impacting changes in closed period" error messages, which has never been a problem (the few users using this tool have the allow G/L changes permission needed), and then we're just getting random blank suitescript errors sometimes. We haven't been upgraded to the 2021.1 release so I can't even blame it on that. Any thoughts about what might have changed behind the scenes? It works for about 75% of our transactions we upload so I just can't wrap my head around why all of a sudden it's not working for some transactions that used to work.
