Mapping Templates

Hi guys,

I'm trying to use a mapping template, but the option "Show Suitable Templates" doesn't appear available when I try to apply my template. I'm doing the following: I have one mapping template based on the same DT’s that I'm using in my message mapping and I mark the element source as well the element target, right-click on the element target and the option "Show Suitable Templates" is showed in grey... Do I miss something?

Note: XI 3.0 SP12

Thanks in advance,

Ricardo.
