Hi @Raviyaramati-1837 ,

Welcome to Microsoft Q&A forum and thanks for posting your query.

One way to achieve this requirement is by utilizing "Add additional columns during copy" feature as explained in this stackoverflow thread - [Transfer the output of 'Set Variable' activity into a json file Azure Data Factory

After your append variable activity, have a subsequent Copy activity and define a column and pass the value of append variable as described in stackoverflow thread.

Hope this info helps. Do let us know if you have further query.

Hello @KranthiPakala-MSFT

i have gone through stack overflow thread earlier as well, but no luck , as it say point dataset to json , but to create dataset we need linked service point connection ,

1) where should we place or point dataset link service to point to

2) if we tried placing source adls link service and created json dataset , but this seems like we to place output of variable to json (sink) , but source , json seems invalid

can you suggest if there is any other way , other than this

Regards

Ravi

Hi @Raviyaramati-1837 ,

Thanks for your response and apologies for the delayed reply.

1) where should we place or point dataset link service to point to

You will have to create a linked service pointing to the sink data store where you would want to write the sink data (csv/json based on the requirement).

2) if we tried placing source adls link service and created json dataset , but this seems like we to place output of variable to json (sink) , but source , json seems invalid - Sorry I didn't get this ask here, could you please elaborate a bit so that we can better assist on this?

Thank you
