Hi,

The instruction provided in the original post by Gianluca should work also in your case, when multiple adapters are involved.
Please consider that point 3., "Develop the custom Adapter Set", actually provides the possibility of developing many adapters, to be precise, each Adapter Set can contain only one Metadata Adapter but many Data Adapters.

Please could you explain better what you mean by " grouped adapters"? Could you also a little expand an the steps you followed?

Regards,
Giuseppe
