Maybe we are unique in having a field that is very long, but having the ability to manually change the width of columns in the ETL would be fantastic.
We have different combinations of materials that can go into our goods, all depending on what has been ordered. In order to make this happen and price things appropriately, we end up with the 3-digit codes per material stacked up, to show the entire BOM.
This means that we at times have 300+ character long data fields (I didn't set it up, promise) that makes the ETL tab of a Data Reader SUPER inefficient to use.
