How to ignore create output file when no data from metadata

I have question about UniversalDataWriter, I would like to ignore create output file If I transform metadata is null.

For example in the attach file. At Reformat, I use ‘if’ condition inside details is:- if the answer is true it will be out in port 1, if fault it will be out for all port.
If in case of answer is true and return out in port 1, the Clover generate output file for all files, that is I do not want. So how I ignore out put file in port 0. Do you have any suggestion?

Thanks,
Jean.

Hi, Jean,

Thank you for your question. We do not have such functionality yet. But I find it useful so I suggested it to our developers.
See https://bug.javlin.eu/browse/CL-2734 for more details.

Best regards,

Hi Imriska,
