Message Mapping Deletion Error

Hi Experts,

I am having a problem deleting a message mapping in ESR. Also, I cannot save modifications I made in the message mapping.

Everytime I try to delete the object it displays the following error.

Error While Executing Delete...

while trying to invoke the method com.tssap.dtr.pvc.versionmg.IVersion.getState()

of an object loaded from local variable 'version'

STACKTRACE:

com.sap.aii.utilxi.swing.framework.ExecuteException: while trying to invoke the method com.tssap.dtr.pvc.versionmg.IVersion.getState() of an object loaded from local variable 'version'

Please help

Regards,

Paolo
