Simple Fix can be
Create a combined filed with "All the reason fields" (It is nothing but string concatenation of all the fields into one field)
drag the field in your summary
Hope this will solve the issue.
Thanks & Regards
Some Order will have multiple reason codes, concatenating them will make it unreadable.
There has to be a new line for each reason code as show in the sample image.
use pivot on "All the reason fields"
which will make data as you require then you can drag the pivot values to your summary.
if your not able to do this , please share the twbx. where i can help you in achieving it
Thanks a lot Pranjala.
I was trying to enable this in the front end using variables, will wait for more answers if any.
