Message Mapping buttons disabled
I have a problem when I want to map identical nodes within Message Mapping .
The problem is that the button "Map Selected Fields and Substructures if Names are identical" is disabled. Not only this button is disabled but all the buttons are disabled, I mean: 'Clear mapping', 'Data Flow Editor', 'Dependencies' and so on...
Obviusly, I'm working in edit mode.
The Xi is 3.0 and SP 20.
Why are these buttons disabled??
Thanks in advance.
all that counts is a correct solution to an issue.
