We had in our system, a number of tax codes created to conform with the VAT 2010 directives (for services). It seems they had been incorrectly set up with EU code "2", at the time of creation. There are postings happening to these tax codes from the required date. However, now we realize that this tax code is not picked in the EC Sales List report, as the EU codes are set as "2", even though we check the "select service" check box in the EC Sales List report.
Going through some of the SAP OSS notes, it appeared to me that the EU code for these should have been "4", to get picked in the report.
My concern is that if we change the EU code from "2" to "4" in the existing tax code set up would it impact the document posted in the past and also after the change will the previous documents posted with these tax codes be reported in the EC Sales List.
Kindly advise on the same.
