Hi,

Is there any reason behind not using transformers inside LOOP?? any performance reason?

Thanks

This is a common misperception caused by an ill-worded error message.

There is no problem with using transformers inside a loop. What you can’t do is try to pass a list (an array) to a transformer that expects a single variable–and this is true whether the transformer is in a loop or not.

The Developer User’s Guide covers this in the section named “Transformers and Array Variables.”
