How can I set the output feature type name so that it consists of a constant part and a variable part, such as "Circle_205", where the number part could be different each time?

When using a fanout, this is easy to set, but without a fanout, I do not know how to do this, unfortunately.

Is there any reason you can't use a fanout? – Mark Ireland Sep 17 '12 at 15:53
Good question! No, there is not any special reason for that, but I was wondering how to do this without using fanout. – Z77 Sep 18 '12 at 8:04
But how to set prefix or suffix fanout to an attribute value? I tried @Value(att_name) but it is not correct! – Z77 Sep 19 '12 at 7:15
Did you see my second link? – blah238 Sep 19 '12 at 7:22
Yes, i tried, but it is different with FME2012 ?!:( – Z77 Sep 19 '12 at 7:23

You probably want to use a dynamic schema on your writer, e.g. set the feature type name to the attribute you create, for example, by concatenating the constant with the variable part.
