Thanks for confirming - Vimal's solution was optimal for you I believe since you can't make use of the 19.2 style paging grid yet.

What version of Appian are you currently using? If you have 19.2+, it would be far easier to get your grid working by using the modern paging grid component, as it works a lot more easily for certain things (like your case) than the legacy version which you're using.

Got you. Your grid line item is based on the OMCAppointmentInfo.

The below expression should help you:

a!foreach(items: index(local!datasubset.data.OMCAppointmentInfo,
expression: joinarray(index(index(fv!item, "AppointeeTM", ""), "FullName", ""), ", "))

Tried but returns error

Interface Definition: Expression evaluation error at function a!gridField [line 110]: A grid component [label=“My Active Milestone Schedules - CO”] has an invalid value for “columns” and “value”. All “data” arrays must not contain more items than the specified “batchSize”, but “batchSize” was 20 and the largest column data array had 22 items.

Hi Meena,

Try index(index(local!datasubset.data.OMCAppointmentInfo,"AppointeeTM",{}),"FullName",{}) ?

It seems like in your expression you are indexing AppointeeTM twice which would return empty value.
