Hi,
I assumed you are using VPN connection right?
In your scenario that is normal since the GUI of SAP B1 is not built for type of connection compare
to SAP ERP GUI.
The only SAP supported type of remote connection is either Terminal Server or Citrix.
In our own scenario we are using Terminal Server and we are very satisfied. We have used
this between to different cities. This is also prevents data corruption cause by intermittent
internet connection.
Hoping you will be convinced of using Terminal Server or Citrix.
By the way, a quick question, why are you hesitant to use RDC or Citrix?
For overview, if your remote requirement is just simple and basic you may use Terminal Server.
The implementation of this is very fast and simple also, what you need is only a license.
If complex and advance features connection requirement connection use Citrix.
For better understanding you may search from the site for the difference of the two.
Thanks.
Regards,
Clint
