Not sure about that! But thanks.
For starters I worked from this document
http://https://www.consolut.com/fileadmin/Medien/PDF/SAP_PrintDoku/en/CAINTUS/CAINTUS.PDF
And the relevant SAP Library docs for sales tax. There was some config setting up that needed to take place and also some program code to load the jurisdiction codes and other data needed. That is pretty general and was on a 4.6 system I think so likely much, or at least some has changed since then.
Once I worked out what to change in config it seemed to go pretty well. But... 8 years can sure fill in some bumps I'm sure we hit on the way.
I can give you a general out line of the config steps, but again they would be specific to our modules so not sure if it would be helpful or not.
