# What is the best way for us to respond to error codes when the problem may seem unclear? q

I've contacted SPS directly a few times about error codes that don't correlate to any obvious issue and they're usually unable to help or tell me. Is this something that needs to change on the business end from businesses sending an order, or is this something SPS should look into to clear up?

I have found the EDI viewer tool here https://ediviewer.ediacademy.com/Home/Upload to be invaluable. It's free to use (just have to create an account)
Download the offending errored text file from SPS Reporting, save it and upload it to this site.
Most times it will show you in red what is bad.
If not, then it is almost always a missing reference (REF*DP*01 Department number, but no dept number listed where REF*DP*02 should be, SKU listed, but no LIN*SK* listed, etc)
When in doubt, you can also try searching for "**" (Two asterisks) in the text file. There shouldn't ever be 2 in a row and if there is, something is missing.
