I want to share one problem which we faced when we upgraded to EHP2.
We came across a situation where we were not able to open SPRO in SAP CRM. Whenever we click on the IMG in Transaction Code ‘SPRO’ to maintain customizing settings then we were getting an Exception.
I want to share this because if someone facing the same problem then he will not have to worry about this.
We were using SAP GUI 7.10 version. That is why we are getting the exception because SAP GUI 7.10 do not support the SPRO in new EHP2 and higher versions.
So what we did to solve this is we simply upgrade our SAP GUI from SAP GUI 7.10 to SAP GUI 7.30 and the problem get resolved.
And now we are able to open SPRO in EHP2 version as well.
