Hello,

Have you try to define the output schema of tschemacompliancecheck ?

Laurent

Ok, and the output schema of the tUnite, is it defined and set as the same of inputs ?

Hi,

You will not be able to connect both input streams in your case since both input streams are part of same subjob and will create cyclic connection.

An option to avoid this is to write the interim data to a temp file and in the next subjob, read the data from all the temp files and do the union using tUnite component.

Regarding: "An option to avoid this is to write the interim data to a temp file and in the next subjob, read the data from all the temp files and do the union using tUnite component."

Yeah that doesn't work because you STILL can't union the flows. Plus the components are in a loop.
