Multiple emails for Single output

Hi Team,

I am creating a data request for fetching zero price sales lines and creating message request for sending the output by email .

But when i run the orchestration i am getting 90 emails for 90 lines of output .Is there anyway i get single email with all the 90 lines having Zero prices.

I tried with following message text :

"Data Requests" : [ {

    "Data Browser - F4211 [Sales Order Detail File]" : [ {Order Number : ${Order Number},

Company         : ${Company},

Line Number   :  ${Line Number},

Order Type     :  ${Order Type}]}]
