Reporting - Data for each row

Hello There,

I am trying to build a report where I have to add special character for each line of the table if its out of spec. The specs are located on different table :


In the picture above, * in round highlight indicates that the value id out of spec but instead of * customer wants to see < or > which I could do with keychain expression. However, I am stuck on getting both row values of spec table

Let say, the spec table data_key is Specification and column is ml_min. How do I get value of detail row 1 and row 2 of that column ?

I have tried - Specification.ml_min[1] which of course didn’t work.

Any idea would be appreciated

Got it :
