We use IRDC since upgrade from TC 8.3 to 11.2. Siemens has configured it for us, so I do not have a lot of details for you. As far as I see you need two components:
1. An IRDC object with the "template". This is de dataset which will be copied from.
2. A rule in BMIDE which tells which template is used when creating which item.
Make sure that the IRDC object is released with a status with the text "release" in it.
I am sure the documentation tells you a lot more. I hope this helps you a bit.
