Specifying the Key in a schema file

[jerome_rajan]

How is the key specified in a schema file? I came across this topic but the solution doesn't help.
I keep getting an error - Unrecognized type-specific format properties: {Key}

Is this really possible?

In the post you mentioned, Ray Wurlod states:

As I mentioned earlier, this information is not obtained from the record schema.

Have a look at any table definition with a key column and look at the Layout Tab (Parallel-Type): there is no indication of a key there.

I recently read an interesting post here concerning RCP and update operations:
