Symptom
I'm using ECC6.0 IDES server, I got the error message "No RFC connection is defined for SAP Global Trade Services" while save an Good Receipt
(MM module).
Solution
Global Trade Services (GTS) is SAP's foreign trade application, which is usually run on a system of its own. There are various user exits
that can be implemented to send currently processed documents to GTS, have them checked -- for example for exports to sanctioned party lists
--, and receive the document status.
I guess your system has one of these implemented but is not customized correctly, i. e. the RFC target is not properly configured, probably
because you do not have a GTS system. One solution would be to deactivate the user exit.
actually you are getting this error because of activating sap golbal trade services.
You have to deactivate that one.
For that use below path.
