How to combine example set in IO Object Collection

hmhsing · May 2017

I couldn't combine the example set shown in each IO Object Collection from Loop Attributes. I tried using Loop Collection, Remember and Recall operators, but not worked. The process XML is attached, hope someone can help me with this. Thanks.

Thanks for your help. Since I used two loops (loop values and then loop attributes in the subprocess), I need two loop collections (one with join, the other with append inside the loop) to combine all the example set together. It finally works, thanks again.
