For Each Item flow logic how to get the consolidated output

[Jamsheer1]

while creating a record I need to get related list of records and perform a REST action for each record . I'm using this flow and its working fine however I've no idea how we can get the final output to a variable.

Basically each REST response will return an unique reference and I wanted to update the concatenate value of response to a field in the table.

I tried this before and only got the value of the last element in the loop as a "concatenated value".

It seems like I would have to input the concatenated value from the previous loop as an input to the concatenation step. How do I get the output parameter the concatenation script as an input parameter so the values will be concatenated?

When I tried this before I was unable to use the 'sumoutput' in the Update Record step and I was only able to get the last iteration record. 

Whats the content of your script to concatenate value action?

Hi Jamsheer,

I believe this is addressed in Quebec with the introduction of the flow variables, More details here - https://developer.servicenow.com/blog.do?p=/post/quebec-fd-whats-new/

You can store the values in flow variables without updating in records and use it finally. 

Thanks

• Create a flow variable 'response'.
• Add new step under rest inside for each loop to set the flow variables.
• Select the flow variable created and use below script inside it,
  
  fd_data.flow_var.response += fd_data._2.1_REST_CALL + '&&&';

  return fd_data.flow_var.response;
  NOTE : fd_data._2.1_REST_CALL have to be checked with your flow and &&& is used as separator for multiple responses.
