We are facing the problem described in SAP Note 912369 and 644610.
The note specify that an rfc connection named FINBTR@<SID>CLNT<MANDT>
must be created.
This rfc connection must have a user/password saved to be used by SAP FIN transport tools.
Unfortunately it does not provide the user profiles that should be given
to the communication user associated to this rfc.
If you have faced this problem, could you please provide us the roles/profiles
that you have given to the communication user?
Thanks in advance.
