Customer Salesperson update

For large import scenarios where I am updating records, I sometimes click the ‘commit’ box on the save line of the import scenario.  This will create an ‘ERP Transaction’ for each line in the import because it will save each line, then treat the next line like a brand new record, but helps when one of the records for the same customer fails.  That way, the ones that do succeed will update, then you can deal with only the failures in the end.  You would never want to do this with importing a one to many record, such as new bills with many lines per bill, for example.  This may not resolve your entire issue, but may make finding the ones that fail a little easier.
