I hope this discussion helps anyone else who gets the following error:
"user xxxxx has no access authorization for for computer yyyyy"
A lot of posts about this error have talked about adding entries to the table SAPFTP_SERVERS and the fact that they were missing entries in it. If you're not familiar with this table, it was recently added by SAP as a "service" to prevent people from using SAPFTP to send files to places amd you could legitimately run into this issue if someone hasn't fully maintained the table IF you are using that table.
BEFORE YOU GO THE ROUTE OF CHECKING THE TABLE, DO THE FOLLOWING:
The one thing you will want to do is to make sure is that the the username, password, and host info are absolutely correct. If any one of them is incorrect, SAP returns the above error instead of telling you something more specific like "username/password combination for the specified site is incorrect". I spent days and an OSS note about this only to find out that my password was wrong because someone else modified it and I wasn't aware that they had done that.
So what SAP is now doing as a result of all the changes to implement table SAPFTP_SERVERS is returning a very generic error message for just about any connection error and it most likely has nothing to do with the table SAPFTP_SERVERS if there aren't any entries in it.
